• I just want to thank you for this most interesting and informative article. I just did a general search for the compatibility of a stoneware glaze on porcelain, and your page came up! Wow! what a mine of information and just what I needed as I was also looking for a slip recipe for my students.

• This article was very interesting and prompted me to write to thank you for the fantastic resources of DigitalFire and Insight-Live. I'm a fairly new potter---both to the craft and glaze chemistry---and your scientific approach is an absolute treat compared to vague advice often trafficked outside of industry. Furthermore, Insight is a wonderfully powerful tool which has defined how I approach testing and analysis of clay and glazes. It's incredibly refreshing to have information usually buried under the expense and jargon of industry journals and textbooks freely available.

• THANK YOU SO VERY MUCH for your continuing contributions to the ceramic world! [Yes, all caps is shouting, intentionally so!] I've been following Digital Fire for about 25 years now. Many of those years passed with my studio packed in crates in storage. I now have leads on space to reopen. You've kept my passion alive through your postings.

• If, like Japan, Canada had a custom of selecting certain artisans as “national treasures“ you would certainly qualify - not only for your expertise as a ceramic chemist, but for your compassion for us less expert potters!

• First of all I'd like to convey all my gratitude and an immense thank you for all the work and research that you make available for the ceramic community, it is invaluable.
