• The knowledge and information you share on digital fire is a rare gem on the internet. I greatly appreciate your writing style. To the point and full of facts. I am wanting to be more active in my glaze creation and begin to make my own glazes. This, to me seems like a huge step away from the safe and what I know of the glazes I have been working with.

• I would like to honour my commitment to the great work you do. It is an invaluable resource! Just a huge thank you!

• 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.

• After more than 50 years making pots, selling and teaching I’m done. Worn to a frazzle. Just wanted to let you know that over the years I’ve relied on you for information on materials and glazes. I’ve never been disappointed, and I owe you a big thanks. I’m over 80 and I need to slow down. I’ll continue making pottery, but not so much. I’ve been at it since 1968 (phew!). I thank you for your advice and especially for your website and its cascading information. Always useful, always on target. I’m only sad that I was not able to meet you in person. Peace, love and happiness.

• 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!'
