Using our Eco - Shell walnut shells for blasting and polishing is easy. First, choose the right size of walnut shells according to your application. For metals and woods, a coarser grade might work well, while for fine jewelry and gems, a finer grade is better. When using them, make sure your blasting or polishing equipment is set up properly. Put the walnut shells into the machine and start the process. As for maintenance, keep the walnut shells in a dry place to prevent them from getting damp. If you find the shells are losing their effectiveness, it might be time to replace them. Also, note that the sizes are based on U.S sieve standards, and the millimeter and inch measurements are approximate. Don't worry about any chemical or heavy - metal hazards as these shells are chemical - free and heavy - metal - free.
