I'm an intermediate potter. I've been trying to teach myself glaze calc
for a while now. For me, the problem is the "format" authors use to
present the math. Once I could figure out where they got various
numbers, I could see what they were doing. It is a problem, too, that
no one author seems to include ALL the various equations, you gotta dig
through all kinds of books. I got so frustrated with the chart format,
I made myself a different format, and made a small posterboard "memory
aid" to use instead. That made all the difference for me. I am still
slow at it, but with my format change I can do the calculations and see
where the various numbers came from. So my suggestion to others
struggling with it is to change the way the material is presented, so
your brain understands. C. A. Sanger

I agree with your concern to know exactly how glaze calculations are
made. One of the problems with computer glaze calculations is that you
just enter the recipe and with a click of the mouse the analysis
appears. This one accepts a gospel and must be correct - which hopefully
it is. However, it doesn't help one with the understanding that you are
seeking.
One of the virtues of using a spreadsheet for such calculations is that
you can see the formula under each cell and so see how it has been
arrived at. This, I consider, is one of the virtues of The Glaze
Workbook file which runs on a spreadsheet such as Excel. (Further
details can be seen on my web site)
