The green and blue backgrounds are porcelain slip with mason stain. Two cups of dried porcelain plus 1/3 cup mason stain, mix with water to desired consistency. Applied with a hake brush on the wheel. Two coats to make sure there was even coverage. For the next go around, I am applying a plain white porcelain slip to help boost some of the colors in firing. I bisque fired and then gave the wares to Hsi-Mei for decoration. When I got them back, I decided to re-bisque to make sure none of the artwork smudged while I was glazing them. My usual preference is to apply underglazes to greenware and then bisque once. But, after seeing the detail of the artwork, I did not want to risk messing them up.
