Does anyone know the way of mixing glazes by volume (i.e.cups) and adding
the colorants you desire to get a good glaze that works ?
I spoke with an older potter who is trying to find her old recipes for
this way of mixing glazes that she used to get a better understanding of
glaze mixing.
If anyone has any information on this please let me know because I am very
interested in knowing before I go out and by a lot of materials for glaze
calculating my own!
Thanks in advance,
Amer

Hi,
My exhusband used to do all his glaze mixing by volume, cups, teaspoons,
etc. I now also do mine that way, but have only used it to add
colorants. For glaze tests I take one tablespoon of the commercial
uncolored glaze and add colorants up to 1/1024 of a teaspoon. That is
usually not necessary as it is such a tiny percentage as to disappear.
If you remember that 48 teaspoons equals a cup then 96 1/2 teaspoons
also equals a cup. If you add 2 more teaspoons (or 4 1/2 teaspoons)
then you have 100 one-half teaspoons in one cup. So.. a 1/2 teaspoon is
equal to one percent. You can add colorants this way to one cup of dry
glaze. However, if you'd like to do a tiny test on only one tablespoon
then you have to remember that 12 one-fourth teaspoons equals a
tablespoon, etc. You can figure it out. The way I get the 1/8 teaspoon
measure it to take the 1/4 teaspoon of dry colorant, turn it over onto a
3x5 card then cut it in half by eye with a sharp knife. To get 1/16,
pile up the 1/8 you just made and cut it in half. Keep going as long as
you like to get the amount you want to try. I have had good luck with
copper carbonate in 1/32 quantities in Laguna's High Gloss White and in
Laguna's Soft Gloss white. Hope this helps. Let me know how you like
it.
