"Awesome program you have!"
"Tony, I looked at Insight Live today more carefully. It is quite an accomplishment! Congrats to you! "
"I personally think that collaborations with the greatest expert in the sector makes me richer in knowledge and it will allow me to discover the fantastic secrets of ceramic."
"You are a real gem, your work really help me a lot."
"First, I want to thank you for all the help we got from Digital Fire; thank you very much for this huge work and to share it like that."
"The program is brilliant and I am thoroughly enjoying it!"
"First I want to thank you for the service you're providing the ceramics community at large."
"Looking at your website, I have no doubts that there is no other person that would be so dedicated to the subject as you. It is a fact that you have a truly unique knowledge of how things are done, the materials and chemistry being used in such processes. Frankly, I do not complement people and their work easily but you are one of a kind person with some divine dedication to the technology. There are very few people like you and that is a fact. I just spoke with several so-called ceramics, frits and glazes experts and I have to say that they had somewhat limited knowledge while you cover incredibly wide spectrum of all affairs involved in to working with all those great materials. "
"I have everything hand written in my notes from my glaze void, but obviously, is not searchable. It's great what you've done."
"You are brilliant .. You have provided so much info that is great. I have been a full time potter for 44 years and am still learning. Thank you so much for your generosity in sending this very pertinent information to me. It certainly has me thinking I should sign on to Digital Fire. Thanks again."
"I am a high school senior AP ceramics student investigating glaze chemistry and rheology. I spend a great deal of my free time browsing the digitalfire reference library, and would have never developed the passion I have for ceramics chemistry had I not come across it."
"Your site is amazing and your videos too. Such an inspiration."
"First i'd love to thank you for all the info you provide on digitalfire. it is an absolutely amazing resource and the way that you explain glaze chemistry/reactions has really helped expand my practice...I crave understanding and wisdom."
"I'd just like to say that I love Digital Fire and I'm on here pretty much everyday. It has been soo helpful. Even though I am still leaning and exploring what I can do with the program it has been a huge help, and I believe it will be for years to come. I'm such a fan of your glaze software and tell all them members here .. what a tremendous asset it is to my practice. "
"I keep telling people that I just found the best ceramic website on the internet. Paid for an account on insight live."
"I love your software and I really appreciate you being there when I need help. Keep on being amazing. I am still enjoying insight every day. You were right - having it in the cloud is a huge advantage."
"Digitalfire is just jaw-droppingly awesome. Thanks for all your hard work."
"Thank you so much for the fantastic info and knowledge you provide for us potters on your page!"
"I am learning so much from your website, even after 33 years in business as a ceramic producer."
"In the 4 decades or so of my academic career, glaze chemistry was one of my favourite subjects, though it was too 'scientific' for most students! Your Insight-Live programme is really super! Thanks once again for all you are doing to keep the discipline alive and kicking."
"I have used the digital fire database for years and am beyond grateful for your work."
"I am a long time fan. I bought your downloadable book long ago and still refer to it frequently. Has bunches of my notes in it too. It expanded my college training with glaze chem. Appreciate you."
"Thank you for this web site. Really thank you. I live in fear that it will disappear one day, so don’t ever delete it please!"
"I just want to thank you for this most interesting and informative article. I just did a general search for the compatibility of a stoneware glaze on porcelain, and your page came up! Wow! what a mine of information and just what I needed as I was also looking for a slip recipe for my students."
"I have not been potting for nearly 20 years. Your website is an oracle. Thank you."
"I am doing pottery now for abut 40 years and nowhere else I could find such an extensive, complete, to the point collection of information than in Digitalfire!"
"Your site is great! It is so good to have your site as I venture into making my food-safe glazes. I live in São Paulo, Brazil, so the raw materials here naturally can be very different from the ones in most of the books and websites, as we don't have much of that available here. So your site is the only that I have found so far that is really helpful if you want to start from scratch, so thank you! Its like my dream as a potter to make beautiful, lasting and safe ware so your website and insight-live are invaluable sources of information for me. I am so glad to be able to work with this! I really admire your work and tell my students about your website. Here in Brazil, studio ceramics is not a very developed area. Many people don not even know/care about being precise and knowledgable about safety with glazes. So your website is like an oasis in the tropical desert."
"I'm a professional potter from Western Australia with a 30 year career - self taught. I came across Digitalfire when researching raw materials - an incredible resource you've put together!"
"Thank you so much for this wonderful resource you have created! I have found all of the information in the Digital Fire database as well as Insight to be incredibly helpful tools in the ceramic world."
"WOW, WOW, WHAT GREAT INFO! thankyou! I am going to pass your site on to someone i know who is more keen on the science of glazes, than the potting, unlike me... she will love your test works and pics Wow! Thanks again. "
"As many other users on the web, I want to congratulate you for your amazing digital fire website. "
"It’s been now a couple of weeks that I learn everyday with you and your amazing project. I find your way of tackling experiments clear, practical and smart. I wish more quality content like yours was available on all of my interest topics! "
"Thank you for your incredible library of information. I have a background in QA (Six Sigma) and Biology so I genuinely appreciate the information you've made easily accessible."
"Thanks for the great application. I have removed GB from many of my recipes and I love learning so much about my glazes instead of just "going wonder how that glaze works". Your resource is invaluable. I will be a lifetime member."
"Your site is a fantastic resource, I recommend it to everyone."
"This is really cool. Thanks for sending this to my email."
"I'd like to say that I am so thankful for all the work you have done by creating and hosting Digitalfire. It has been an unparalleled resource for me as I learn more and more about glaze chemistry. I really enjoy your articles and photo comments and I'm just fascinated by the well of knowledge that seems to spring forth from them. "
"I join others (I'm sure) in thanking Tony for the incredible resource that is the digital fire library, and for the insight glaze calculation software and now website. Not a week goes by when I don't use all three of them and usually quite extensively."
"Thank you again for the amazing website and wealth of information!!! InsightLive is proving to be an incredible asset as well!!!"
"Thanks! I look forward to seeing your posts. I have read and printed many things you have posted over many years. Have learned a lot from you."
"Thanks so much this info is so great!!"
"Yet again, you provide a quick answer not easily found elsewhere (a bowl was befuddling me with wall cracks that never made it to any edges.)"
"I teach glaze technology at ... the information that you display on your this website is absolutely fundamental for my teaching."
"Thanks Tony for your excellent stuff. I am learning a lot. Its of complete knowledge at ease. God bless you !!! "
"I'm a brand new "student" of glazes and clay bodies, and I have used your site as an incredible complete information source. Thanks for that. "
"I spent most of yesterday playing with the “new” (to me) version of insight on line. I love it, it is faster and eventually easier to use. And by the way, thank you for creating and maintaining the enormous data base of ceramic materials and making it available for anyone to use. What a wonderful gift to all of us interested in ceramics."
"Thank you very much for your website, as a amateur Potter I find it an incredibly useful source of information about all kinds of things pottery related and when I'm trying to make glazes for example I will often refer to your website for guidance."
"I am a big fan of your work. I want to thank you for being there when I have needed and hopefully I will be able to carry on without much input from you. I will be renewing my subsrciption soon and I extol the virtues of the program (and now the Cloud version) to everyone that will listen."
"I wanted you to know that, you have a fantastic program. Every serious potter should use it. And it would be a good starting curriculum for high school and college to learn from. Thanks for, I would imagine, many hours in developing time. Kudos sir. I hope, by God's good will that I will be able to enjoy it for any years to come."
"Your site, I think, is the best source of information on ceramics that I have found. I have always wanted to know how things work rather than just doing it because someone said so. Your site gives reasons why and how to apply what you have learned! I've learned much from you and now I am enrolled in chemistry classes to better understand what you present on your site. Thank your for the Digital Fire Website and the Insight-live Site."
"A big thank you for sharing your vast knowledge through this site. I have spent many an hour scouring your articles and learning. Your depth of understanding of so many different aspects of ceramics often exceeds what is available in many books."
"Please continue this brilliant service!"
"Hey Tony, just like to say thanks for your fantastic site as it has been the best reference guide for my helper and I."
"I love insight BTW. I have been showing everyone at Alfred how easy it is to do UMF while comparing two recipes next to each other. The up and down toggles make it easy to understand cause and effect. They are also impressed how easily i can switch between my computer and smartphone and maintain all my work and recipes. BTW I just love insight. It has changed my experience and knowledge of glazes drastically. "
"It's very impressive work you do. Thanks you for providing it."
"Thank you for your time, and I am totally excited that I woke up to an email from Tony Hansen (I’m a big fan)"
"I am a production potter and I have been using your website for information, and I have made many improvements from articles posted on this site."
"Thanks Tony. You are offering a very valuable service to the potters."
"Your site is the most useful of them all for material info. and more. Thank you."
"Love the email I got today about the clear glaze because I have an account! Thank you for all you do. These emails are a great idea."
"I write to appreciate your good works by way of the articles you made available on the net .. Thanks a million for your good work. From Nigeria."
"Thank you for the amazing information. I couldn’t find an online ceramics class that I could take to learn about clay and glaze chemistry, so I am thankful that I found this. Is there a way I can donate to support the site?"
"I have to say as the subject says i am completely blown away by the amount of valuable information I have just taken in over around 4 hours or reading through your vast content and watching your videos on youtube! I am now a big fan and will for sure sign up with an insight live account as soon as I can!"
"Thanks for doing the timeline. I’ve told you before but it never hurts to say it again, this is great stuff and I get so much info from your posts. Extremely valuable!"
"I read your articles for years, and it really helped me to better understand ceramics."
"I have mostly used store bought glazes and fooled around some with stains. I have never approached anything scientifically. Your website seems wonderful. Seems that I could spend a few years with what you have shared. I will start with one of the base recipes and let the fun begin."
"First of all I want to say that your website is just incredible. So many great information and tips!"
"I would like to honour my commitment to the great work you do. It is an invaluable resource!"
"Love the post (about leaching in glazes). I am the bad guy on Facebook ceramic because I always bring up this subject. So sad."
"Having explored and taken lots of advice from your site, I just wanted to say what a brilliant and informative site it is."
"Extremely useful resource Digital Fire. By the way your writing style is truly unique and is easily understandable even though of technical nature. "
"Your site is a crucially important one, and I'm happy to help you, even in small ways. "
"I want to thank you for creating all that extensive and wonderful material in Digital Fire and Insight Live. I have started with the process of creating my own glazes a little bit more than a year ago, process that I found exciting and challenging and thanks to your websites it has been a lot easier!"
"When it comes to new technology, I'm still thrilled with the chainsaw as apposed to an ax. I really do like glaze testing. You see a recipe in a book but it doesn't do you a lot of good until you can see it on a tile."
"I have done production pottery at cone 10 and 5 for 40 years, but during almost of full year of downtime due to COVID, I am exploring low fire terra cotta. Digital fire is an amazing resource. Thank you so much."
"Tony, you're a gentleman and a scholar. Thanks for the information. I'm a self-taught potter living in Hansville, WA. could not have done it without your scientific approach and papers. "
"BTW, thanks for creating such a great site."
"THIS IS FRIGGIN' AMAZING! YAY! NOW I NEED GLAZE MATERIALS! WOOT! I'm blown away by your site. I'm totally going to geek out on this I can tell. Item #1 on my agenda is to stop being at everyone else's mercy for glazes."
"I would like to thank you, I have looked through books and books and books, and here you are with so much fantastic information about what to do with the free clay that we can find outside. Even just saying that the clay has to be dry when you put it in water, what an eye opener. I am so amazed how well this works. "
"Hello Mr. Hansen. Your digitalfire.com site is AMAZING! I use it considerably. Thank you so much for all the information you offer! I tell all my students and friends in clay to come here to learn. "
"Tony - thank you so much! The information that you directed me is better than I could have imagined. I it has helped me learn more about how to drive a glaze formula design toward outcome objectives."
"And I want to add - you are doing a magnificent job with your webpage. Just unbelievable amount of work and information you put there. I have learned a lot from your webpage. Thank you. "
"I'm accepting the challenge. First: find/develop a good base recipe. One for clear and one for celadon. Then add the colors. And play with "surface." Experiment. Keep impeccable notes. Change one variable at a time. Yada, yada."
"Thanks for this and for the incredibly useful information on your sites."
"First off, I want to thank you for building Digitalfire. It is an incredibly valuable ceramic resource."
"Thank you for your very informative website - it is a real help to one who has spent 40 years potting."
"I simply want to let you know that the digitalfire reference library is a treasure. Every time I look it up I learn something new, and I have a hard time to tear myself away. I have a number of books on my shelf, but if I had to choose just one reference source, it would be digitalfire. There is an enormous amount of work behind all the entries in the library. For me, it has enriched my practice and helped me advance in a way that cannot be measured."
"Just read your page and I am awestruck!"
"You have no clue how much this site has inspired and helped me develop my love for ceramics and chemistry."
"Absolutely love the insight-live web app."
"You have done more for the advancement of ceramic knowledge than anyone I can think of. Thanks again! The information you provide and the work you have done is invaluable. I can't tell you how many problems I have solved because of insight and the reference library! Thanks again for all of the help you have provided."
"Many thanks for your time and trouble, re the information cone 6. You are a wealth of generosity and help to the home Potter. "
"This article was very interesting and prompted me to write to thank you for the fantastic resources of DigitalFire and Insight-Live. I'm a fairly new potter---both to the craft and glaze chemistry---and your scientific approach is an absolute treat compared to vague advice often trafficked outside of industry. Furthermore, Insight is a wonderfully powerful tool which has defined how I approach testing and analysis of clay and glazes. It's incredibly refreshing to have information usually buried under the expense and jargon of industry journals and textbooks freely available."
"How amazing it is to have personal contact on such an amazing technical site and I can’t express my gratitude for your generous spirit. "
"I discovered your website after trial and failure for 35 years. WOW ! The questions you have answered for me and the knowledge are immeasurable To think I am going to get past the Science and onto the Art makes me near giddy. Your site is amazing. My college age kids are going to be dazzled I did this. Every single college ceramic studio should know about your site. I want to tell them! "
"Thank you very much for creating these examples and explanations. I am getting a much better understanding for why Frits are so much better. Now that I am digging into InSight-Live and manipulating the chemistry, this documentation is the main place where I can find the facts and suggestions that help clear up my questions. Thank you for creating such a very practical and wonderful upgrade . The interface is so nice and even forgiving. Thank You Very Much,"
"I just wanted to say, thank you! I’m relatively new to pottery, taking a mostly self-taught approach and I’m at the stage where glazing is in my mind. I don’t want to be (and can’t see myself ever) buying glazes from commercial suppliers. I want to learn my craft with glaze as much as I do with my clay preparation and pottery making. I’ve seen “the dragon” and been uninspired by so much of what I find online and to be honest, in many glaze books. It seems more popular to try and present a mass of glaze possibilities than to offer a learning experience beyond being told a glaze needs a melter, a refractory and a glass-maker. Enough to offer a very basic understanding, but nothing upon which to build the understanding that will allow some degree of mastery (or at least influence) of your glaze making. I am so pleased to have found digitalfire.com. You’ve shown me exactly how to approach and understand glazing, giving me the foundation for approach I sought. I was thinking of base glazes and what you’ve shown me about working on from those is fantastic and exactly what I was looking for. To have a reliable base glaze to modify and develop to meet different needs; to understand how to shift a melting point or adjust the surface gloss; to come to know how the mechanisms in a glaze and understanding them gives me the route to creating glazes that realize my intentions - wow! I can’t thank you enough. Rather than having to form a dumb reliance on a book of recipe cards and a bunch of website bookmarks (which I wasn’t wanting to go for) you’ve given me the foundation for a lifelong development and understanding of the glazes I will make, that will become “my” glazes. You have really opened my mind to the whole subject and it doesn’t seem to be a problem that I’m no scientist or chemist. You’ve shared your knowledge in a way that is completely approachable and remarkably easy to understand for someone without any kind of science/chemistry background. "
"Awesome site...you do great work!"
"I work at a small, but rapidly growing custom slip-cast studio. The first few years were a learning curve gauntlet that, in retrospect, I am surprised we exited intact. This preface is to give a sense of how in debt I am to your research and hard work. I have had to learn as I go along, and the information you provide at digitalfire.com has been indispensable, and, quite frankly, an excellent cover for my ignorance on countless occasions! It is also the only source of information about many ceramics topics that I feel I can trust, knowing that it has been backed up with careful consideration and testing. Thank you again."
"Hey Tony, thanks so much for developing such a useful software. I have come to digital fire for countless questions I have had with clay and glazes."
"I am a computer/tech guy and was drawn to your info because it is systematic, detailed and comprehensive. I started pottery and wheel throwing January 2018 on my 59th bday. I am ecstatic! "
"I want to first tell you that your site is amazing. i love the approach, the attitude, and the incredible information. the fact taht you share so much of your information to the public is truly wonderful. I recenly fell in love with ceramics and set up a home studio."
"I have longed admired your website, and everything you've contributed to better understanding ceramic technology."
"I'm glad I was of some small service. Your whole venture is a marvel. All the best as we go forward."
"As a side note: most of the students did access your information in their presentations. I found it interesting that your work is becoming foundational."
"THANKS. I WOULD BE LOST WITH OUT YOUR WEB SITE AND INSIGHT SOFTWARE."
"Learning ceramics has been a long process full of tests, frustration but at the end full satisfaction once we learn more every day... Thank you for your website, I use it for constant reference"
"Love Insight-live. Have been using it a few months and now that I know my way around a bit, I have come to rely on it. Love having a web based program, since I bounce between Windows on several machines and also a Chromebook."
"Anyway I thank you for your efforts in putting together this wealth of ceramic science in this accessible manner. "
"I am a long time admirer of your ceramics data base and teach at ... University."
"I have learned alot from you."
"I think the work you do with glaze chemistry is invaluable and amazing. And unique to the industry."
"Insight live is great...!"
"I've really appreciated using your insight-live.com software."
"I am a ceramic manufacturing manager, and before this position, I had no training on ceramics. I was taught our recipes, but none of it was explained. The dragon ran amok. After reading through your articles and descriptions, I feel I have learned so much about my own products, and I have a foundation for changing, improving, and troubleshooting my materials issues that I wouldn't have had otherwise. They taught us in engineering school that we all stand on the shoulders of giants, because we all get to use knowledge and tools at a moment's notice that took others years to develop. Thank you for sharing all that you have, so the rest of us can stand on your shoulders to do our work that much better."
"I am eternally indebted to you for all that you have done to advance the technical abilities of non-industrial pottery! I love using Insight."
"I have been following your Site and posts continually and gained a greater understanding. Thank you for that. It is so exciting to have a positive outcome from your glazes rather then the bought glazes. ... All good and exciting. My pottery clients are excited and have recognized the difference. There is nothing better than to pass on the best work possible to those who love the pots. So much work and testing, but well worth it. Thank you so much. "
"I have really been enjoying using insight."
"My glazes activities are seasonal anyway. In the summer i make pots in winter I think about chemistry and sit at a PC. I looked at your pricing again and it is indeed reasonable."
"Your website is like a encyclopedia for ceramics, whatever problem I have I first go to your website and refer to it and learn and understand about it. Thank you so much for your patience and time for helping."
"Dear tony: Nice work keep it up! "
"Planarity in 1200c tile May 2018"
"I am a Brazilian potter and, despite my difficulty with the English language, I have learned a lot from this site. I want to thank you very much for the immense help you give me in the "most difficult times". "
"I just want to say THANK YOU for this incredible database of information. Thank you, thank you, thank you!"
"Thanks, Your enthusiastic new subscriber."
"Many, many thanks for DigitalFire! It is a wonderful collection of information and experience. "
"I should mention beforehand that you, as well as Insight, have become the “go to” reference for all technical aspects of my work and those of other potters I know. It has become an invaluable resource. Congratulations on your academic approach to everything ceramic."
"Had quite quite a few problems learning to enter recipes."
"Please know that your work is really benefiting me in my work. I really was helped by your information about drop and soak at cone 6. I've had trouble with an otherwise beautiful glaze which develops blisters. Thanks for your 'Insight!'"
"Just wanted to say thanks for such a great and useful product. Been learning via pen & paper, which I don't regret, but I should've signed up a lot sooner. "
"I just wanted to express my appreciation for digital fire. It's an invaluable resource that I've been using since I was 18 years old (more than a decade). Keep up the amazing work."
"Sure do like Insight and I've switched to using the live version. It's excellent! "
"Superb. Very interesting study (about frit melting behaviour). Wow. What a patient effort!"
"I think you have done a great job in developing the on-line version. It is very easy to use. We meet once a month to discuss any glaze problems, test glazes in teams, and I do a presentation on an aspect of glaze chemistry. One day, I said something technical and one of the member's jaw dropped and she said "Hey, I just realized I understood what you said". It was a proud moment."
"Also thank you for the quality of your website, I've learned so much from it."
"Am learning to use Insight, love the articles in the reference database. Thank you for everything you have done and are doing."
"Thanks for sharing your extensive knowlege with the clay community."
"You are due many complements on your site and software. I usually have your A - Z materials dictionary open in my web browser."
"The articles contained very helpful. I work for luxury table ware well known brand from UK. "
"Thank you for all of the information you publish on your website. Digitalfire has been my primary resource for researching raw materials and I will be soon be subscribing to Insight. Thank you so much for all of your work. My fellow students and I refer to your website almost daily. "
"Thank you for all the info you put into Digital Fire, it's an invaluable resource!"
"I love all the tips and insight live is a lot of fun as well as being an amazing tool. Thanks"
"The knowledge and information you share on digital fire is a rare gem on the internet. I greatly appreciate your writing style. To the point and full of facts. I am wanting to be more active in my glaze creation and begin to make my own glazes. This, to me seems like a huge step away from the safe and what I know of the glazes I have been working with."
