Using our studio glazes, matt black interior and on top edge of exteriors, then satin white over that down most of the exterior, and a final dip about the lower third into our raspberry glaze...which gives a different shade of grey. And yes, there were 4 mugs made...one just lagged behind in the glaze kilns.
You've seen some of these in their "before stage" when the glaze had just been applied. HERE.
The thought I'm following for the next batch is to use Georgia O'Keeffe colors and huge bright flowers.
