• I've said it before, but I can't say it enough, thank you for all your work on digitalfire and insight.

• I join others (I'm sure) in thanking Tony for the incredible resource that is the digital fire library, and for the insight glaze calculation software and now website. Not a week goes by when I don't use all three of them and usually quite extensively.

• 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.

• And I don't know how to thank you enough for your help with your website. What a wonderful and complete tool you provide. It is my bible!

• Thank you very much for your website, as a amateur Potter I find it an incredibly useful source of information about all kinds of things pottery related and when I'm trying to make glazes for example I will often refer to your website for guidance.
