• I write to appreciate your good works by way of the articles you made available on the net .. Thanks a million for your good work. From Nigeria.

• 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.

• I am a potter of over ten years and am now in this year paying attention to my glazes and what goes in to them. It's been an awesome journey with plenty of "ah ha" moments and exponentially more "what the..." moments. Regardless of what I'm feeling, digital fire is so far the best resource I've encountered. I’ve been going about glazes all wrong, following recipes and stabbing in the dark hoping to find one that Works for me... well, it’s not working! I’m devoting my time to explore glaze chemistry even more than I have and to do this I am convinced I can not go forward efficiently without a test kiln. THANK YOU for these wonderful resources!

• Love Insight-live. Have been using it a few months and now that I know my way around a bit, I have come to rely on it. Love having a web based program, since I bounce between Windows on several machines and also a Chromebook.

• Dear tony: Nice work keep it up!
