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've recently purchased your software, and am totally blown away by the completeness of the package. The tutorial is incredible, I've learned so much from it already! This will be invaluable to me; glazes have always been somewhat mysterious, and I've relied far too heavily on the Kiln Gods. I'm looking forward to completing the tutorial and start experimenting.... As to the software, as an old Foxpro programmer myself, I can appreciate what it took to do what you did."
"I am getting better at using Insight for what it is intended in the ability to select different materials to provide the various oxides and to compare them to target glazes. I have also used Insight to review recipes to decide whether I want to try them or not, given the likely characteristics and avoided wasting my time with poorly constructed recipes."
"I enjoy using INSIGHT."
"Thank you for all the work ... good info that you have put into Insight. It is well worth the money. I like your philosophy, you come highly recommended."
"It looks TERRIFIC!"
"Your support for Linux is a big reason why I purchased your program."
