• Thanks for this and for the incredibly useful information on your sites.

• We love your work with Digital Fire. You've single handedly breathed life into many, many ceramics companies through your generous approach to sharing information. I can't tell you how valuable we have found your content to be. Thank you.

• I'm a professional potter from Western Australia with a 30 year career - self taught. I came across Digitalfire when researching raw materials - an incredible resource you've put together!

• Thank you for everything you do online, I've learned a lot from your blog and continue to do so (I'm an art school graduate and in spite of our curriculum having included a glaze chemistry course, our professors lacked an industry background, which does offer many additional insights)

• 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.
