• I've literally been using your website for Glaze chemistry since I was a neophyte in Glaze making I didn't think you were a singular person I thought it was a corporation of people who made the website.

• Love Insight-live. Have been using it a few months and now that I know my way around a bit, I have come to rely on it. Love having a web based program, since I bounce between Windows on several machines and also a Chromebook.

• I wanted you to know that, you have a fantastic program. Every serious potter should use it. And it would be a good starting curriculum for high school and college to learn from. Thanks for, I would imagine, many hours in developing time. Kudos sir. I hope, by God's good will that I will be able to enjoy it for any years to come.

• You have such a brilliant analytical mind, able to find solutions to many ceramic problems. You have accomplished so much in your life, helping us potters understand what we are doing. I cannot thank you enough for your vast ceramic reference library online. I think you are a national treasure.

• Yet again, you provide a quick answer not easily found elsewhere (a bowl was befuddling me with wall cracks that never made it to any edges.)
