• After more than 50 years making pots, selling and teaching I’m done. Worn to a frazzle. Just wanted to let you know that over the years I’ve relied on you for information on materials and glazes. I’ve never been disappointed, and I owe you a big thanks. I’m over 80 and I need to slow down. I’ll continue making pottery, but not so much. I’ve been at it since 1968 (phew!). I thank you for your advice and especially for your website and its cascading information. Always useful, always on target. I’m only sad that I was not able to meet you in person. Peace, love and happiness.

• Anyway I thank you for your efforts in putting together this wealth of ceramic science in this accessible manner.

• The body of work you present, and the obvious attention you have paid to your website, is quite noteworthy. To me it’s a bit like AutoCad: it has everything, but you need training in how to use it!

• You’ve been a great partner and we’ve benefited tremendously from Insight over the years.

• We love your work with Digital Fire. You've single handedly breathed life into many, many ceramics companies through your generous approach to sharing information. I can't tell you how valuable we have found your content to be. Thank you.
