Description

This is a urethane plastic replica cast of the jaws and teeth of a medium-large (original skull is about 13″ long) polar bear. This cast measures 6″ long (from the front center incisors to the last upper molars, on a diagonal, only the upper jaw measurements are given) and 3 1/4″ wide. It includes all the detail of the original, down to the pores in the bone and wear on the teeth. The cast is filled with yellow urethane foam for stability, and the foam makes it easy to machine and accepts hot glue (and other non-waterbased glues) really well. This would be perfect for mask making or educational use. The cast can be painted if desired, but you will need to do some minor surface preparation. I get good results from light scuffing with a very fine grain foam sanding block (120 grit or finer) and then cleaning the cast thoroughly with denatured alcohol (rubbing alcohol would also work, as would acetone), since there will be some mold release naturally present that will repel paint. Then you can prime it with ordinary canned automotive-type primer (white primer works best and is easiest to paint over) and then paint with pretty much any kind of paint, including water-based acrylics. Then you can seal it or laquer it to protect the finish.
