• 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 think you have done a great job in developing the on-line version. It is very easy to use. We meet once a month to discuss any glaze problems, test glazes in teams, and I do a presentation on an aspect of glaze chemistry. One day, I said something technical and one of the member's jaw dropped and she said "Hey, I just realized I understood what you said". It was a proud moment.
• It’s been now a couple of weeks that I learn everyday with you and your amazing project. I find your way of tackling experiments clear, practical and smart. I wish more quality content like yours was available on all of my interest topics!
• I have not been potting for nearly 20 years. Your website is an oracle. Thank you.
