This porcelain bowl was made in two steps. The base was made using a hand-building technique with coils. Then the surface was decorated with blue and white porcelain (the consistency of porcelain was changed to achieve a more liquid state). As you can see from images the surface is uneven and resembles an acrylic painting. Please note that the surface is very tactile it's not smooth, but the base is sanded.
