• 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.

• 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.

• 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.

• 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.

• You are an essential source -- I am a huge fan and spread the word when someone asks me a technical question.
