I work in bronze clay and I find that after firing the metal is dull even after polishing. I even changed the carbon recently. Can you tell me a solution to this problem?

There can be a myriad of reasons why your bronze pieces are still dull after polishing. Here are a few of the recommended polishing methods:
Materials
- Use a mild abrasive, such as pumice, for a soft, not bright, shine. Dip a damp finger or a baby toothbrush into the pumice powder and rub the metal in small circles until the desired shine is achieved
- Polish pieces with 600 grit (grey) micron-graded polishing paper
- Use a rotary grinding and polishing tool
- Wire brush the surface for a satin finish
- Polish your pieces in a tumbler using a shot mix of varied shapes and enough water (an inch above the items) and a squirt of liquid dish soap
Materials
