Download it from the Files panel in your Insight-live.com account (it costs $15 for 6 months access). Current downloads only include the program file, starter recipe, materials, overrides data is built in. It functions as level 2, without need of a key. No features have been removed. It will never expire.
No. Insight-live has a much broader scope and is far superior, it is the future (it still does the chemistry but is much more about data and access-from-anywhere). We still support desktop Insight for users who need to convert data for import to insight-live or who must work off-line.
There is a direct relationship between the way ceramic glazes fire and their chemistry. Insight is a calculation tool anyone can use to learn and harness the power of glaze chemistry.
Without glaze chemistry you'll never really have control and you could be a slave to your suppliers or the trafficing in recipes that never work.
A desktop application for Windows, Linux, Macintosh that you download and install.
Insight was first released in 1979 and has been used world wide since. It is an excellent teaching tool for demonstrating the principles of formula/analysis/unity, limit formulas, LOI, and material-oxide relationships.

"I have a large experience in characterization of ceramic materials ... development of glazes and pigments (several publications in renowned magazines and encyclopedias) ... I find the website, the database and the software of Digitalfire very good and I would like to offer my help as a consultant or editor."
"Well, I must tell you that you are currently my hero and I am spreading the word about INSIGHT to any of the potters I know that will listen, (although I must confess that I think many get scared to death when I talk about glaze chemistry.)"
"My impression is that a large proportion of students passing through Higher Education in Ceramics either are not taught the Chemistry or are not interested in it. It seems that the Aethsetic or Creative side is more important. However maybe I am old school but I believe that you can't build a house unless you know how to lay bricks."
"Given the chance, I would like to say how helpful I have found the program. With what I have learned about glaze formulation from reading and workshops, Insight makes it easy to apply and evaluate my findings."
"Insight has been a big help to me in understanding my glazes and making new ones. Best money I ever spent for software."
"I am a beginner potter setting up a studio at home. Having an extensive background in chemistry, I was elated to find a site addressing all the questions I had. I knew I didn't want to take the 'glaze junkie' approach. THANKS!!!"
