Hi Scott,

The Matrix website has a large alphabetically listed collection of materials
with indexes linked to the data for each material. This resource may be =

Hi everybody,
I'm new to the clayart list.

I was wondering if any of can help me obtain a glaze materials database.
I would like to download a data file which contains common chemicals
with formulas to use in my glaze calculation program. I am (attempting)
writing my own program using the Perl programming language.

Why am I writing my own glaze calculation software? Well, all I have at
my disposal is a workstation which runs on the UNIX operating system. I
therefore cannot run any free glaze calculation software because they
run on PC's or McIntosh.

Or, if any one knows of a web site that runs interactively, that would
be even better.

Any help would surely be appreciated=21

Ababi, I noticed a difference in your glaze
calculations compared to mine. This is what I expected
on a glaze that could be tricky. I also note that you
used Matrix which I did for the Edwards Red. Now we
will have to compare materials and their up-dates and
see how close a match can be made between your
materials and mine. Contact me off list in a few days
since I will be gone. Its a matter of imputting the
correct and latest up-dates in the system and finding
out if we do have the same materials or equal
materials to use? I think most of my chemicals I have
on hand now are correctly installed with the
manufactuers specs. Who knows? Its a full time job
keeping up.
For the record your expansion was much lower and a
showed a difference as well in surface tension. Can
you send me the specs you are using on Neph Syen so I
can take a look there.

Well its time to go see the family and have some yule
time in the mountains. Take care and Merry Christmas
