• I just want to thank you for this most interesting and informative article. I just did a general search for the compatibility of a stoneware glaze on porcelain, and your page came up! Wow! what a mine of information and just what I needed as I was also looking for a slip recipe for my students.

• Many thanks for your time and trouble, re the information cone 6. You are a wealth of generosity and help to the home Potter.

• 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 spent most of yesterday playing with the “new” (to me) version of insight on line. I love it, it is faster and eventually easier to use. And by the way, thank you for creating and maintaining the enormous data base of ceramic materials and making it available for anyone to use. What a wonderful gift to all of us interested in ceramics.

• Thank you! Tony for all of the impressive work that you have contributed to our industry over the years. Your glaze work has been super helpful.
