I love this little pottery piggy bank that my mother made years ago in a class. The interesting look it has was made by a certain ceramic firing process called raku which uses both smoke and fire to create unusual patterns and textures. The pottery is first bisque fired, then glazed and then undergoes a firing and smoking process. I remember doing it once and I believe we placed the objects in the ground to achieve our smoke affect. Maybe I'll make a print of pigs to go along with it. Someone has made a deposit into this bank but there's no way to retrieve it!
