glaze calculation programs

I was very interested to read of your use of spreadsheets for glaze
calculations. In my view they can be used very effectively for glaze
calculations and I have developed such for use with MS Excel, Lotus 123,
QuatroPro, Super Calc and MS Works. These are all, however, for use with
PC's using Windows not Apple Macintosh.
The MS Excel version is particularly good as it not only enables one to
you use drop down selection boxes and macros but also pop up notes. The
use of pop up notes means that on-screen help and information is
available not only for general instruction on usage, but also to give
such things as oxide limit data and raw material compositions. Another
advantage of any spreadsheet version is that all the formulae can be
accessed and hence, if you are interested, you can see exactly how the
calculation has been carried out. For the student this may be important
as a learning tool. Converting a recipe to a formula is easy in any
program, but the reverse of constructing a recipe from a formula may be
more difficult. I think the spreadsheet has many advantages in this,
particularly if based on MS Excel.
