• I've literally been using your website for Glaze chemistry since I was a neophyte in Glaze making I didn't think you were a singular person I thought it was a corporation of people who made the website.

• 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.

• Tony, you are wonderful!

• Please know that your work is really benefiting me in my work. I really was helped by your information about drop and soak at cone 6. I've had trouble with an otherwise beautiful glaze which develops blisters. Thanks for your 'Insight!'

• If, like Japan, Canada had a custom of selecting certain artisans as “national treasures“ you would certainly qualify - not only for your expertise as a ceramic chemist, but for your compassion for us less expert potters!
