Look to photos for examples of the type of cup you will receive. Handmade by Renata Wadsworth. "My pottery is made predominantly from porcelain...clay that encourages the intense carbon-trapping I look for in my shino surfaces. A light soda spray at about cone 8 further enhances these effects. The wood kiln is then brought to cone 10-11 and cooled slowly over 2-3 days."
