Newbie here. I've been experimenting using different colored clay bodies and even colored clays using oxides and stains. Mostly for neriage/agateware technique. So far i've been leaving the exterior unglazed to show the true colors of the clay (usually buff, with ochre, white, or bclay). I've tried to glaze my pieces using an cone 6 oxidation clear glaze and cone 10 reduction clear glaze, but i find that the clay colors gets "covered" up by the glaze. Expecially in cone 10 where most of my dark clays (with iron) turns grey.
Can anyone suggest an alternative glaze or material that will show through the clay underneath? tips?
