• This article on porcelain is terriffic. I've been slip casting my own porcelain formula for nearly 40 years, and wish I had read it way back when I was first starting out! You provide exceedingly useful information- especially pertaining to the difficulties of trying to maintain consistency in a world of materials that are changing rapidly or disappearing entirely!

• 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.

• How amazing it is to have personal contact on such an amazing technical site and I can’t express my gratitude for your generous spirit.

• 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.

• Thanks for your amazing resources at digital fire. They have been invaluable in understanding clay, as I’m getting started with ceramics. Your emphasis to focus on the chemistry has made the art of ceramic very accessible indeed.
