• First, I love your site so much! Thank you for the countless hours that have been put into this!
• The program is brilliant and I am thoroughly enjoying it!
• 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.)
• Anyway I thank you for your efforts in putting together this wealth of ceramic science in this accessible manner.
• Also thank you for the quality of your website, I've learned so much from it.
