To expand on John's post - it turns them green if you don't
simultaneously increase the Tin Oxide. By increasing both the chrome
and tin a more intense shade (or more saturated at any rate) colour
will be produced. By altering the ratio of chrome to tin you will
alter the colour. Less chrome, more tin will be pinker, more chrome
less tin will be mare maroon (at least that's what I'd call it). As a
general rule of thumb you want the chrome:tin ratio to be between
about 1:10 to 1:20. YMMV. Obviously base glaze is also tremendously
important.
