• I'm accepting the challenge. First: find/develop a good base recipe. One for clear and one for celadon. Then add the colors. And play with "surface." Experiment. Keep impeccable notes. Change one variable at a time. Yada, yada.

• I have used the digital fire database for years and am beyond grateful for your work.

• 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.

• Insight has become an important part of the ceramic industry for some time; this is my opportunity to express my gratitude.

• I think you have done a great job in developing the on-line version. It is very easy to use. We meet once a month to discuss any glaze problems, test glazes in teams, and I do a presentation on an aspect of glaze chemistry. One day, I said something technical and one of the member's jaw dropped and she said "Hey, I just realized I understood what you said". It was a proud moment.
