• 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.

• Renewed today, your site is invaluable to me. I will continue to re-up until they take the sponge out of my cold hand! Thanks.

• Tony - thank you so much! The information that you directed me is better than I could have imagined. I it has helped me learn more about how to drive a glaze formula design toward outcome objectives.

• I teach ceramics and have been doing it a long time. I am also a subscriber to your site. You are a Godsend and a wealth of information, and I appreciate you sharing your knowledge with our community. So I've been doing this a long time, and ceramics never ceases to humble me.

• I am learning so much from your website, even after 33 years in business as a ceramic producer.
