What would cause clear coat pottery glaze to turn milky and bubbly when fired in the raku style?
My clear turns milky if it is to thick , so try adding some more
water to it.
If it is bubbly, fire it longer and maybe a little higher. All
Raku glazes bubble up as they
heat up. You usally have a window to watch it fire. Keep firing
till it lays down smooth
as glass.
