• I teach glaze technology at ... the information that you display on your this website is absolutely fundamental for my teaching.

• Tony, we've never met, but I want to chime in with the many others who have contacted you, telling you how important your work has been to the ceramics community over the years. I am a potter today because of people who took me under their wing and showed me everything they know for the love of the craft, and because they believed in access to knowledge and education for all who want to work in clay. The spirit of the ceramics community is with people like you who do it for the love of the craft, and money second (which is not to say you aren't deserving of plenty of the second as well). Your program is an instrument of democracy, as funny as that may sound. In a world of paywalls, you make information available to all.

• I just wanted to say, thank you! I’m relatively new to pottery, taking a mostly self-taught approach and I’m at the stage where glazing is in my mind. I don’t want to be (and can’t see myself ever) buying glazes from commercial suppliers. I want to learn my craft with glaze as much as I do with my clay preparation and pottery making. I’ve seen “the dragon” and been uninspired by so much of what I find online and to be honest, in many glaze books. It seems more popular to try and present a mass of glaze possibilities than to offer a learning experience beyond being told a glaze needs a melter, a refractory and a glass-maker. Enough to offer a very basic understanding, but nothing upon which to build the understanding that will allow some degree of mastery (or at least influence) of your glaze making. I am so pleased to have found digitalfire.com. You’ve shown me exactly how to approach and understand glazing, giving me the foundation for approach I sought. I was thinking of base glazes and what you’ve shown me about working on from those is fantastic and exactly what I was looking for. To have a reliable base glaze to modify and develop to meet different needs; to understand how to shift a melting point or adjust the surface gloss; to come to know how the mechanisms in a glaze and understanding them gives me the route to creating glazes that realize my intentions - wow! I can’t thank you enough. Rather than having to form a dumb reliance on a book of recipe cards and a bunch of website bookmarks (which I wasn’t wanting to go for) you’ve given me the foundation for a lifelong development and understanding of the glazes I will make, that will become “my” glazes. You have really opened my mind to the whole subject and it doesn’t seem to be a problem that I’m no scientist or chemist. You’ve shared your knowledge in a way that is completely approachable and remarkably easy to understand for someone without any kind of science/chemistry background.

• Tony, as I am writing a porcelain book, you will be amazed to know how much info is coming from your lifelong work. AI constantly uses your information.

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