• I wanted to let you know that I greatly appreciate all the knowledge you have shared with me over the years. Its made an enormous difference in the quality of my work.

• Thanks for your amazing resources at digital fire. They have been invaluable in understanding clay, as I’m getting started with ceramics. Your emphasis to focus on the chemistry has made the art of ceramic very accessible indeed.

• 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.

• Yet again, you provide a quick answer not easily found elsewhere (a bowl was befuddling me with wall cracks that never made it to any edges.)

• Thanks Tony. You are offering a very valuable service to the potters.
