If you are using stains, you want to avoid using ZINC. Even a tiny
amount will ruin the color of any chrome/tin stains ( crimsons,
pinks, purples). In addition, you need a fair amount of calcium to
develop the color. Check your base glaze--if it fits the parameters,
you should get a lovely plum with one or more stains.
