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

• In the 4 decades or so of my academic career (I taught ceramics as a major of the Fine Art degree at the University of Kwa-Zulu-Natal, South Africa), glaze chemistry was one of my favourite subjects, though it was too 'scientific' for most students! Your Insight-Live programme is really super! Thanks once again for all you are doing to keep the discipline alive and kicking.

• You have such a brilliant analytical mind, able to find solutions to many ceramic problems. You have accomplished so much in your life, helping us potters understand what we are doing. I cannot thank you enough for your vast ceramic reference library online. I think you are a national treasure.

• I must say you have so so much good information and with examples that it is nothing less than outstanding. I've added another year to my account. Thank you!

• This site is an incredible resource and I just want to thank you for it. It fills in so many gaps from my studio art ceramics education and has made me more confident in the pieces I sell. I reference it almost weekly and have recommended it to so many other potters. The ceramics world is better off learning and applying this wisdom and I'm so happy to see someone teach so technically and seriously about the material. Culturally, there is a casualness in the pottery world (whether in community studios or school art rooms) that is borderline negligent in some ceramic circles and I just really appreciate when I see someone pursuing excellence and technical mastery of the material. Because it really matters!
