• I'm a brand new "student" of glazes and clay bodies, and I have used your site as an incredible complete information source. Thanks for that.

• 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.

• I teach ceramics and have been doing it a long time. I am also a subscriber to your site. You are a Godsend and a wealth of information, and I appreciate you sharing your knowledge with our community. So I've been doing this a long time, and ceramics never ceases to humble me.

• You are due many complements on your site and software. I usually have your A - Z materials dictionary open in my web browser.

• Awesome site...you do great work!
