• 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 high school senior AP ceramics student investigating glaze chemistry and rheology. I spend a great deal of my free time browsing the digitalfire reference library, and would have never developed the passion I have for ceramics chemistry had I not come across it.

• I have done production pottery at cone 10 and 5 for 40 years, but during almost of full year of downtime due to COVID, I am exploring low fire terra cotta. Digital fire is an amazing resource. Thank you so much.

• Am learning to use Insight, love the articles in the reference database. Thank you for everything you have done and are doing.

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