ZAKIN'S CERAMIC UTILITIES    November 11, 1988

On this disk are two analysis programs, some material to
help you understand ceramic analysis, some information on
various subjects which interest me and a whole bunch of
analyzed and annotated formulae. I hope that you like this
packet of material.


TWO GLAZE ANALYSIS PROGRAMS     

By Richard Zakin (flow charts) and John Kane (programming).
The first of these programs, called glaze, goes from recipe
to analysis formula (listed in a percentage format). The
second program is called analyze and it goes from an analysis
(in percent form) to materials formulae. These programs were
written in Basic by John Kane of the Economics department of
SUNY Oswego using charts worked up by Richard Zakin of the
Oswego Art Department. To use these programs on a two disk
machine: 

1. get system prompt 
2. put program disk in drive a: 
3. call up program To use these programs in a machine with
one hard disk and one floppy (writing data to floppy) 

1. get system prompt 
2. call up program 

The Glaze Program

The glaze program lets you take a typical glaze recipe and
break it down to its component elements. It is simple to use
and fairly easy to understand. I have included some ancilary 
material which will help in this.

What To Do When You Enter The Glaze Program

First name the formula; this name is for your convenience
and can be long and discriptive. It is not read by DOS and
need not conform to Dos's naming conventions. You are now
shown a list of materials; you may add new materials at this
time if you need them. You are now faced with a list of
materials each with a number by it: start by picking a
material, write in its number, press enter. Now you are asked 
how much of the material you want to use, write in this
number. Go on to the rest of the materials in the glaze. You 
may change percentages in midstream. When you are satisfied
with the formula press 0 to get an analysis. You are now
asked if you wish to print, to write to disk or both. 
 Personally I write to disk
and then work over the material with my word processing
program and print from that program. 

Writing to Disk

If you are writing the analysis results to the same disk as
the one containing the program just write the new filename.
If you are writing to another disk write the disk drive
letter, a colon and the filename (e.g. a:redglz). The name
you give the file is read by DOS and it must conform to DOS
conventions (eight characters or less and a three character
extension). 

You may now start a new formula or modify the old one or
quit. 

Quitting 

If you want to quit wait until you see the quit prompt (Q?)
then press Q and you will be let out of the program and let
into basic. To leave basic write the word, system. That gets
you back to the b: prompt. 

The Analyze Program

The Analyze program is similar in its action to the Glaze
program. Once you enter and name the formula you are required 
to write the element analysis. You then pick a material
number and its percentage and try to get close to the
original analysis with the materials which you normally use.

The analysis program requires a fair level of knowledge and
familiarity with percentage analysis methods of examining
glazes. How do you get this? Read some good technical books
and use the glaze program to analyze your glazes.

FINAL NOTE

We think that this is a great program for the experienced
potter, simple, small and unbossy. We are trying to sell it
cheaply in order to recoup our investment in time and
computer hardware. If you are copying this from a friend
please send us the $18.00 which we charge when we sell the
program. In this case it doesn't cost much to do the right
thing and we think that most potters are pretty honest
anyway.
