I'm experimenting with setting up glazes for brushing, and have read
that adding "a little" glycerin or propylene glycol. How much is "a
little"? I've tried adding about 10% by volume and it seems to improve
brushability, but I'm not sure if this qualifies as "a little" and
whether too much might be harmful in some way.
My current best effort is the following:
100 g dry glaze
70 ml water
10 ml propylene glycol
1 g veegum cer
Seems to work reasonably well, although some glazes seem to be
considerably thicker than others with these proportions, depending I
guess on the proportion of clay in the glaze? Would adding a little
deflocculent in that case be a good move?
Would be grateful for comments and suggestions!
Thanks,
Bruce Lucas
