• 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.

• BTW, thanks for creating such a great site.

• 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.

• Tony, I owe you a tremendous debt of gratitude. In art school, I got a thorough grounding in ceramics -- in a macro sense. Micro, not so much. You, then, are the professor who is helping me to complete my education, via Digitalfire -- truly a Phenominal piece of work.

• 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.
