• 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.

• Tony, you're a gentleman and a scholar. Thanks for the information. I'm a self-taught potter living in Hansville, WA. could not have done it without your scientific approach and papers.

• I want to thank you for creating all that extensive and wonderful material in Digital Fire and Insight Live. I have started with the process of creating my own glazes a little bit more than a year ago, process that I found exciting and challenging and thanks to your websites it has been a lot easier!

• My glazes activities are seasonal anyway. In the summer i make pots in winter I think about chemistry and sit at a PC. I looked at your pricing again and it is indeed reasonable.

• I take this opportunity to appreciate your efforts in sharing all the information related to ceramics on the Digital Fire website. It is really helpful. I am from India. We work towards reducing mining for natural resources by 60% through making (fired) recycled ceramic products.
