Birdlings Flat Stones After First Stage of Polishing

These stones have spent one week in a tumbling barrel with 100-mesh silicon carbide grit. This first stage of the tumble-polish process removes the weathered outer layer of the stone and brings out its colours more clearly. Many of these stones will be quartzites.

Just out of the barrel and having the slurry washed off – plastic pellets also present, used to provide some cushioning to minimise the stones striking one another

Drying before being examined individually to decide what happens next to each stone
