Some great links
I've known about Grainger Pottery in Marion, Ma for quite a few years. Marion is a quaint little seaside town on Buzzard's Bay. My parents have summered there for the last decade and their home has quite the collection of fish pottery. A gold cod hangs over their garage all the native fish of Buzzards Bay and the island grace the walls- Taugtog , striped bass, bluefish, false albacore, fluke and more. I asked hem where they got the hand they pointed me to Geoffery and his wife Karilon's shop on Rte 6. I've always made it a point to visit this shop at least once every summer.
Geoff makes his pottery from actual fish, much like I do but instead of making prints- he casts the fish in plaster and then molds clay to the mold, glazes, paints and finally bakes them in a kiln. Geoff invited me down pick up some fish he had already cast- i gladly took him up on his offer. Here are some photos of his shop.
These are the plaster molds cast from actual fish.
After being cast a flounder waits to be glazed.
