Grotto Gemstones Workshop Tip

Apply polishing compounds sparingly and use light, controlled pressure. Keep separate felt accessories for different polishing compounds to prevent abrasive contamination and unwanted scratches.

Safety: Avoid excessive pressure and heat build-up, particularly when polishing Australian opals. Wear suitable eye protection and follow your rotary tool manufacturer's operating recommendations.
