If two pots are identical in appearance and one is wood fired the other
gas are they different.
If you prefer wood regardless of appearance perhaps you should prefer
glazes calculated with a slide rule.
First thing I did after I really understood glaze calculation was write
a program for the mainframe at Uof Mich, late 1975. Even with having to
go to the computer lab, and punching cards it was a great savings in
time. Cost 23 cents a recipe or so I think. I think that most of the
savings in glaze calc from software is having all the information
readily available and all in the same format.
The Rhodes book was the only guide I had. It is a great book but it
presents glaze calc in a complicated way. Once I understood it and
really analized what I was doing I just hit my head and realized I
understood the principles before I started and that if the problem was
just stated really clearly I would have known how to answer it.

I also learned to calculate from the description in the Rhodes book.
The great failure in that method was the use of generic formula for the
materials. In order to get any reasonable accuracy you need to use typical
analysis of the materials you are using - and those used to by others - if
you want to try to duplicate a glaze.
The point is - use the most accurate analysis you can get - which means
from the mine when you can get em.

I didn't. I tried to teach myself using that book twice when I ws in grad
school, and could never figure it out from his explanation and example.
Years later, I did teach myself how to do it using other books. Only then
did I figure out that the math in Rhodes' book's example was wrong! No
wonder I never could make sense of it!
