• 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.

• We've referred to your site so many times over the last year and I can't express how incredibly valuable a resource it is.

• I am a Brazilian potter and, despite my difficulty with the English language, I have learned a lot from this site. I want to thank you very much for the immense help you give me in the "most difficult times".

• Your understanding and explanations of glazing process and chemistry are always fascinating. Like the help you give for us amateurs, but also I love the posts explaining how commercial facilities deal with cost and efficiency issues like getting production products rapidly glazed and fired without defects.

• Tony, I owe you a tremendous debt of gratitude. In art school, I got a thorough grounding in ceramics -- in a macro sense. Micro, not so much. You, then, are the professor who is helping me to complete my education, via Digitalfire -- truly a Phenominal piece of work.
