• This site is an amazing resource. I'm getting back into pottery after about a 25-30 year hiatus, and back then technical information like what you share was almost impossible to come by.

• Thank you! Tony for all of the impressive work that you have contributed to our industry over the years. Your glaze work has been super helpful.

• I think you have done a great job in developing the on-line version. It is very easy to use. We meet once a month to discuss any glaze problems, test glazes in teams, and I do a presentation on an aspect of glaze chemistry. One day, I said something technical and one of the member's jaw dropped and she said "Hey, I just realized I understood what you said". It was a proud moment.

• I have not been potting for nearly 20 years. Your website is an oracle. Thank you.

• 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.
