If you’ve devoted weeks or months to polishing a collection of rocks, it can be very disappointing when they turn out dull or hazy, here are the likely reasons why and how to fix them.
Tumbled rocks may lack shine for several reasons:
- Use of unsuitable tumbling rough.
- Improper cleaning between tumbling stages.
- Poor quality grit or polishing compounds.
- Misuse or lack of tumbling media.
- Rushing through the tumbling process.
- Rocks need a burnishing step
