• 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!

• I'm a professional potter from Western Australia with a 30 year career - self taught. I came across Digitalfire when researching raw materials - an incredible resource you've put together!

• You are such a godsend, Tony. Even though I taught ceramic science for 30 years I find myself constantly using your site and learning something every time. Just want to say thanks, thanks, thanks….

• I use the site often and appreciate all the information you share so willingly. Mostly the site is a fantastic reference and has profoundly improved my understanding of glaze chemistry.

• I am a long time fan. I bought your downloadable book long ago and still refer to it frequently. Has bunches of my notes in it too. It expanded my college training with glaze chem. Appreciate you.
