This Ohio bowl was handmade by me, JMN Pottery :) After forming the bowl it was dried and bisque fired. After the first firing I glazed this design onto the surface of the bowl with a glossy black glaze and then added a light tie dye glaze over the top. The outer shell of the bowl is glossy black. It was then refired. Food Safe!!! 13 x 12 inches wide 4 1/4 inches tall
