• I join others (I'm sure) in thanking Tony for the incredible resource that is the digital fire library, and for the insight glaze calculation software and now website. Not a week goes by when I don't use all three of them and usually quite extensively.

• Just wanted to say thanks for such a great and useful product. Been learning via pen & paper, which I don't regret, but I should've signed up a lot sooner.

• Looking at your website, I have no doubts that there is no other person that would be so dedicated to the subject as you. It is a fact that you have a truly unique knowledge of how things are done, the materials and chemistry being used in such processes. Frankly, I do not complement people and their work easily but you are one of a kind person with some divine dedication to the technology. There are very few people like you and that is a fact. I just spoke with several so-called ceramics, frits and glazes experts and I have to say that they had somewhat limited knowledge while you cover incredibly wide spectrum of all affairs involved in to working with all those great materials.

• When it comes to new technology, I'm still thrilled with the chainsaw as apposed to an ax. I really do like glaze testing. You see a recipe in a book but it doesn't do you a lot of good until you can see it on a tile.

• I take this opportunity to appreciate your efforts in sharing all the information related to ceramics on the Digital Fire website. It is really helpful. I am from India. We work towards reducing mining for natural resources by 60% through making (fired) recycled ceramic products.
