Miscellaneous Obsidian Cutting and Knapping Rough:
Fireworks Obsidian, Snowflake Obsidian, Starry Night Obsidian
Obsidian comes in many types. Rainbow and color sheens produce unusual cabochons
and knapped items. The sheen is the result of the play of light in the flow
layers of the volcanic glass. Although obsidian has a reputation of being
difficult to polish, we have found that if the stone is ground through successively
finer grits and the stone isn't heated too much during the polishing stage,
that a high polish can be obtained with cerium oxide, or diamond. Mohs hardness
5 to 5.5.
Fireworks Obsidian Rough - $4.00/pound
Locality: Mexico
Fireworks Obsidian cuts unusual cabochons. The surface of finished cabochons
will have a crackly surface, but the stones are still fabulous. This material
is not good for knapping.
