• 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….
• Love the email I got today about the clear glaze because I have an account! Thank you for all you do. These emails are a great idea.
• I am a computer/tech guy and was drawn to your info because it is systematic, detailed and comprehensive. I started pottery and wheel throwing January 2018 on my 59th bday. I am ecstatic!
• I am a high school senior AP ceramics student investigating glaze chemistry and rheology. I spend a great deal of my free time browsing the digitalfire reference library, and would have never developed the passion I have for ceramics chemistry had I not come across it.
• You are due many complements on your site and software. I usually have your A - Z materials dictionary open in my web browser.
