• The program is brilliant and I am thoroughly enjoying it!

• Thank you for all of the information you publish on your website. Digitalfire has been my primary resource for researching raw materials and I will be soon be subscribing to Insight. Thank you so much for all of your work. My fellow students and I refer to your website almost daily.

• I have found your website to be extremely helpful because of your analysis of glaze chemistry and other information too. I have been able to mix all my own glazes and troubleshoot with the information you provide. I want you to know how much you're helping fellow potters all over the country and I truly appreciate your generosity in sharing the information.

• On a small aside. I want to thank you for all the work you have done over the years, firstly to inspire people like myself to see the technical side of ceramics as such a beautiful side of the art and not just a finished result that was lucky. And on that note with how much I read your blog, waiting for daily posts, reading all the old articles again and again, I see your mugs with the wheat grass on them all time, and was wondering if you ever put them up for sale. It's been an icon of my learning and would love to have one of the infamous mugs themselves.

• I would like to thank you, I have looked through books and books and books, and here you are with so much fantastic information about what to do with the free clay that we can find outside. Even just saying that the clay has to be dry when you put it in water, what an eye opener. I am so amazed how well this works.
