I'm really eating this stuff up Hermes. Thanks again!
I'm curious, the KNaO on the chart is separate. Is the KNaO limit different from the separate KO and NaO limits? I kinda new to this so you'll have to excuse any silly questions on my part.
Hi. Marcia answered and, I agree it might be confusing. I often thought to change that in my graphs when I was filling a record. But, for me also K an Na are behaving different so I leave it like it is. The trouble may be that Na OR K may get out of limit individually but when you sum up KNaO appears to be OK.
For anyone who needs a refresher on glaze chemistry or just needs a good introduction to the basic concepts, please follow the numbered parts of Hermes posts on "Keeping Records". This information is presented in a clear concise manner with charts. It is excellent.
Many, many thanks for the support and the kind words!
It is very interesting that you come from a chemist' background. John Hesselberth also comes from that background. I really appreciate your chart. I come from a visual artist background and charts really make sense to me. I had several glaze calculation classes back when we used slide rules. (dating myself??) I have old hand drawn charts of the ratios. I hope others who don't have the background will read what you are posting. It is a valuable resource.
Thanks so much.
Thank you for your interest. I hesitate long before doing this. Our fellow member DocWeathers encouraged me to do so and he reviews part of my posts. My thanks go to him as well.
