• 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 just want to say THANK YOU for this incredible database of information. Thank you, thank you, thank you!

• Thanks for the great application. I have removed GB from many of my recipes and I love learning so much about my glazes instead of just "going wonder how that glaze works". Your resource is invaluable. I will be a lifetime member.

• I am a long time fan. I bought your downloadable book long ago and still refer to it frequently. Has bunches of my notes in it too. It expanded my college training with glaze chem. Appreciate you.

• First, thank you for your site. I am approaching the subject from a more technical side of things rather than decorative or functional pottery but I have found the knowledge you share to be some of the most practical and useful information I have seen anywhere.
