• WOW, WOW, WHAT GREAT INFO! thankyou! I am going to pass your site on to someone i know who is more keen on the science of glazes, than the potting, unlike me... she will love your test works and pics Wow! Thanks again.
• 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.)
• Thanks for this and for the incredibly useful information on your sites.
• I have used the digital fire database for years and am beyond grateful for your work.
• 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.
