• Tony, you're a gentleman and a scholar. Thanks for the information. I'm a self-taught potter living in Hansville, WA. could not have done it without your scientific approach and papers.

• Hello Mr. Hansen. Your digitalfire.com site is AMAZING! I use it considerably. Thank you so much for all the information you offer! I tell all my students and friends in clay to come here to learn.

• 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.

• I have been using Digitalfire for 10 years to help me understand and develop glazes and clays and I can’t thank you enough for all of the efforts you have put into this. You are a huge resource and thank you!

• I am a long time fan. I bought your downloadable book long ago and still refer to it frequently. Has bunches of my notes in it too. It expanded my college training with glaze chem. Appreciate you.
