• 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.

• I spent most of yesterday playing with the “new” (to me) version of insight on line. I love it, it is faster and eventually easier to use. And by the way, thank you for creating and maintaining the enormous data base of ceramic materials and making it available for anyone to use. What a wonderful gift to all of us interested in ceramics.

• As a side note: most of the students did access your information in their presentations. I found it interesting that your work is becoming foundational.

• Let me be the next person to thank you for putting this amazing material together. Insight-live + Digitalfire has catapulted me up the learning curve.

• I have learned alot from you.
