• 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!

• 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.

• This site is an incredible resource and I just want to thank you for it. It fills in so many gaps from my studio art ceramics education and has made me more confident in the pieces I sell. I reference it almost weekly and have recommended it to so many other potters. The ceramics world is better off learning and applying this wisdom and I'm so happy to see someone teach so technically and seriously about the material. Culturally, there is a casualness in the pottery world (whether in community studios or school art rooms) that is borderline negligent in some ceramic circles and I just really appreciate when I see someone pursuing excellence and technical mastery of the material. Because it really matters!

• The chemistry from G3806E really helped me with fixing a copper that I could never get to stop blistering before, so I'm a big fan.

• A short, but comprehensive description with lots of needful information like yours is rarely to be found in the internet. Bravo!
