• 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 found your website, and am thrilled to see documented experimentation in ceramics. At 77 years old, I have taken up pottery and I enjoy every aspect. At the university I took courses through the 500 level, but never saw anything that approaches your site.

• You are an essential source -- I am a huge fan and spread the word when someone asks me a technical question.

• I've really appreciated using your insight-live.com software.

• 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.
