The challenge is before us. Because of the price and ease of usage, an awful lot
of potters can explore working with computers. The more potters use them, the more
quickly programs and applications will be developed and shared. We could put together
a worldwide ceramics information library in one computer; individuals could gain
access via their personal computers and modem interfaces. And if the system is two-way,
anyone would be able to augment the information in the database.

STONEWARE 1 NOTES
Stoneware 1( to the left) is a simple program for generating unified molecular glaze
formulas for Cone 9 It systematically varies the relationship of CaO to KNaO for
each ratio of Al2O3 to SiO2.
The values of X, Y, and Z determine the limit formula range of the various oxides;
you can experiment with changing the values for different cone ranges. The value
for the STEP in each FOR line sets the amount of change for the oxides for each time
through the loops; this can also be altered. If you have a line printer, change
each PRINT and SCROLL in the program to LPRINT. Also delete lines 1001 and 1030
which slows down the display on the screen so you can read or copy it on paper. The
variable names have been chosen for clarity, so CaO is the variable name for the
number of moles of CaO. You could change the particular fluxing order if you wish.
As it is listed Stoneware 1 will generate 19,800 glaze formulas. It was designed
to be easily understood by those just learning programming. For those who know how
to program, it should be considered a subroutine to be used in more extensive programs.
