• I wish to thank you for letting people like me use the information you have on the endless glaze articles you do, for free. Yes I am embarrassed not contributing but sadly currency exchange rates makes payment at the moment way out of my league. However, should you prefer I don't use your amazing site please let me know. Again my thanks for the glaze education I am getting from you.

• 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.

• It's very impressive work you do. Thanks you for providing it.

• 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.

• This site is an incredible resource and I just want to thank you for it. It fills in so many gaps from my studio art ceramics education and has made me more confident in the pieces I sell. I reference it almost weekly and have recommended it to so many other potters. The ceramics world is better off learning and applying this wisdom and I'm so happy to see someone teach so technically and seriously about the material. Culturally, there is a casualness in the pottery world (whether in community studios or school art rooms) that is borderline negligent in some ceramic circles and I just really appreciate when I see someone pursuing excellence and technical mastery of the material. Because it really matters!
