Obsidian Large Chunks

$30.00

This beautiful black stone is a type of Volcanic glass. Its highly lustrous, reflective undulating surface lends itself to textural mosaics. You can use it as an alternative to black smalti or can combine it with other materials to give your work an extra dimension.

 

Concentric semicircular patterns can be present on some of the larger pieces. This pattern is created because of the way the rock fractures when split, this is called a conchoidal fracture and is very appealing when used as a focal point in a textural mosaic.

 

Wrap the chunk in a towel and strike with a lare hammer to break it down into smaller peices. You will get a combination of smaller chunks and flakes.
