• I work at a small, but rapidly growing custom slip-cast studio. The first few years were a learning curve gauntlet that, in retrospect, I am surprised we exited intact. This preface is to give a sense of how in debt I am to your research and hard work. I have had to learn as I go along, and the information you provide at digitalfire.com has been indispensable, and, quite frankly, an excellent cover for my ignorance on countless occasions! It is also the only source of information about many ceramics topics that I feel I can trust, knowing that it has been backed up with careful consideration and testing. Thank you again.

• Awesome program you have!

• I join others (I'm sure) in thanking Tony for the incredible resource that is the digital fire library, and for the insight glaze calculation software and now website. Not a week goes by when I don't use all three of them and usually quite extensively.

• 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 have loved this work since I was young and I find great pleasure in this work until I finish it with the highest quality. I repeat my congratulations to you on this wonderful achievement in your work. You are always welcome and I love receiving your messages. My sincere greetings to you and all members of your honorable family.
