The best specially selected Dacite Tumbling Rough for tumbling and small cabbing. Dacite is a naturally slow-cooled variety of obsidian. It is a natural volcanic glass, with a very consistent battleship gray color and tumbles to an almost nonmetallic hematite look. Dacite is less glassy, grainier, and more opaque as compared to black obsidian.
- Mixed sizes--includes pieces up to 3 inches for tumbling & small cabbing
- Sold by the pound
Specifically selected during the processing tons of dacite for flintknapping for the best size and shape product for tumbling. Not a mechanically crushed stone, these pieces are hand broken from dacite blocks with copper tools and cleaned to reduce cracks.
Dacite polishes well with rotary tumblers, vibrating tumblers, or by using a combination of both. Like all stones, rotary in stage 1 removes stone much faster.
