• Your information has really been a Godsend to so many challenges we have overcome. All of your efforts have really made such a HUGE difference in our studio, rarely is there a day where your shared knowledge directly or indirectly is part of my life. We are eternally grateful for what you have unknowingly (until now) done for us.

• I keep telling people that I just found the best ceramic website on the internet. Paid for an account on insight live.

• In the 4 decades or so of my academic career (I taught ceramics as a major of the Fine Art degree at the University of Kwa-Zulu-Natal, South Africa), glaze chemistry was one of my favourite subjects, though it was too 'scientific' for most students! Your Insight-Live programme is really super! Thanks once again for all you are doing to keep the discipline alive and kicking.

• I have mostly used store bought glazes and fooled around some with stains. I have never approached anything scientifically. Your website seems wonderful. Seems that I could spend a few years with what you have shared. I will start with one of the base recipes and let the fun begin.

• Thank you for all of the information you publish on your website. Digitalfire has been my primary resource for researching raw materials and I will be soon be subscribing to Insight. Thank you so much for all of your work. My fellow students and I refer to your website almost daily.
