How to Cut & Polish Abalone Shells
- 1). Soak the abalone shells in copper sulfate to remove algae and parasitic infestations. Scrub, dry and sand blast the shells to ready them for cutting.
- 2). Cut the shells under water using the various cutting tools to form the desired rough shapes. As the dust from the calcium carbonate in the shells can cause silicosis, you should wear a respirator and use fans for ventilation when cutting the shells.
- 3). Place the cut shell parts into a tumbler for 24 to 72 hours using three changes of grit. Wash and buff the shells, either with a buffer or by hand, to bring the full luster to the surface.
- 4). The shell pieces are now ready to be drilled or set to create an individual piece of jewelry.
