Hi all,
I'm new to glaze stuff as my background is in Porcelain Enamel
formulation and manufacture.
My query is to do with molecular formulae.
I have tended to deal with glass formulae only on oxide and mineral
batch layout as this was what was needed for development of enamels
which are fully fritted glasses. (it's relatively simple when you only
have one body ..steel with a known expansion.. a firing range of 780 -
860 Celsius and a firing time in the hot zone of 4-7 minutes )
Getting them fully chemically resistant and non toxic tends to tax you a
tad.
(I still have difficulty in adapting to the extended trial sequences
with glazes)
Back to script..
I have several fast compiled DOS programs which will do the calculations
in seconds or fractions using preset calculation routes and I would like
to adapt them to calculate unity formula which may or may not be a
trivial task.
Query. What goes where?
The alkali I can deal with. Alumina I can also and Silica
BUT.. B2O3 seems to move between the amphoterics in some cases and the
Acidic or Glassformers where _I_ would naturally put it. (I presume
Antimony goes with Alumina but correct me if I'm wrong)
Presumably also using the balance between SiO2 Al2O3 and the Alkalies
you can do a rough estimate of the cone ..B2O3 would distort this. Is
this so as if I can incorporate this it would be nice.
Sorry for the ramble but I'm curious and hope someone can help.

Just make your program flexible enough that the user can put it
where he wants it.
