• Superb. Very interesting study (about frit melting behaviour). Wow. What a patient effort!

• Extremely useful resource Digital Fire. By the way your writing style is truly unique and is easily understandable even though of technical nature.

• Your site is great! It is so good to have your site as I venture into making my food-safe glazes. I live in São Paulo, Brazil, so the raw materials here naturally can be very different from the ones in most of the books and websites, as we don't have much of that available here. So your site is the only that I have found so far that is really helpful if you want to start from scratch, so thank you! Its like my dream as a potter to make beautiful, lasting and safe ware so your website and insight-live are invaluable sources of information for me. I am so glad to be able to work with this! I really admire your work and tell my students about your website. Here in Brazil, studio ceramics is not a very developed area. Many people don not even know/care about being precise and knowledgable about safety with glazes. So your website is like an oasis in the tropical desert.

• After more than 50 years making pots, selling and teaching I’m done. Worn to a frazzle. I’ve returned to my first love, painting. Just wanted to let you know that over the years I’ve relied on you for information on materials and glazes. I’ve never been disappointed, and I owe you a big thanks. I’m only sad that I was not able to meet you in person. Peace, love and happiness.

• I'd like to say that I am so thankful for all the work you have done by creating and hosting Digitalfire. It has been an unparalleled resource for me as I learn more and more about glaze chemistry. I really enjoy your articles and photo comments and I'm just fascinated by the well of knowledge that seems to spring forth from them.
