Alternative onyx polyester is made from a cast polyester resin. The material works similarly to most hardwoods. It can be machined, drilled, threaded, carved, and turned. When turning it is recommended that you use a tool with a negative rake.

Cast polyester resin can be glued using a various types of glue. In general white PVA is used for larger areas and superglue for smaller areas.

Depending on the tool used the finish can be very smooth and may only require sanding with NyWeb pads. For polishing we recommend Chestnut Products Burnishing Cream, Brasso or equivalent. With a small amount of effort it is possible to achieve a glass-like finish.
