• 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.

• Thanks for sharing your extensive knowlege with the clay community.

• Your work is so thorough and helpful Tony. When I read your articles I suddenly feel I know nothing, despite working professionally with ceramics since 1997!

• I would like to thank you, I have looked through books and books and books, and here you are with so much fantastic information about what to do with the free clay that we can find outside. Even just saying that the clay has to be dry when you put it in water, what an eye opener. I am so amazed how well this works.

• First of all, thank you SOOOO MUCH for all that you do for the pottery community. This site is such a wealth of information and the work and time you put into maintaining and updating it astounds me.
