Hello Pat,
I have a glaze calculation thingy program on a disk, but have never
plugged it into the computer. It's been about a year since I bought it.
Just doing fine, so far. Where does that put me, out in Limboland?
(note: Limboland ain't so bad, and I'm male). So what do you mean by
"has"? I has one, but hasn't used it (yet).
I know, da gurus will want to spank me for this, but feel I must warn da
gurus that I know how to spank too! I've always suspected that da gurus
need minions more than the minions need da gurus.
Slap happy,
Paul Herman

Dear Paul Herman ,
I have one of the original glaze Calc Programs, courtesy of Dr Hogg
and R. Zakin, in genuine DOS mode. No fancy frills, no bells, no
whistles. Use it when I feel idle.
Unless a person has a specific need to do glaze calculations, "why
bother ?".
My own personal opinion is that Seger and Unity representations are
great if you have a need to convert someone's recipe so that you can
fashion their glaze out of your own materials. Should that be
necessary then always bear in mind assumptions and conjectures,
including those that are concealed and judge the results accordingly.
Remember, being able to re-format or "Tweak" a glaze has nothing to do
with Glaze Chemistry. It may be a very useful skill and good to have
available when it is needed and I am pleased some generous people do
this as a kindness for other Clayart Buddies.
A glaze calc program will not tell you why Copper oxides are unstable
materials or if they are unstable in all circumstances. It will not
explain that if you create Barium Monoxide (BaO) in a glaze that
compound can react at red heat to form an unstable compound, Barium
Peroxide (BaO2). Such knowledge is not found books written for Studio
Potters and Ceramic Artists.
Stick to your guns and keep that disk in reserve.
Best regards,
Ivor Lewis.

Dear Edouard,
Yes, simple and almost free.
somewhere in my stash of CM there is a program that can be loaded into
the computer. I must look out and when one of the grandsons comes
again, ask him to show me how to put it imput the new computer.
In any case, I have no problems in feeding information into MS Excel.
Leaving Clayart for a while to catch up with some projects and do some
practical claywork now that cooler days are coming. Have enjoyed your
contributions and our occasional exchanges.
Sincere regards and best wishes,
Ivor.
