• I use the site often and appreciate all the information you share so willingly. Mostly the site is a fantastic reference and has profoundly improved my understanding of glaze chemistry.

• Your website is like a encyclopedia for ceramics, whatever problem I have I first go to your website and refer to it and learn and understand about it. Thank you so much for your patience and time for helping.

• I'd like to say that I am so thankful for all the work you have done by creating and hosting Digitalfire. It has been an unparalleled resource for me as I learn more and more about glaze chemistry. I really enjoy your articles and photo comments and I'm just fascinated by the well of knowledge that seems to spring forth from them.

• 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.

• Had quite quite a few problems learning to enter recipes.
