EISCO Obsidian Specimen (Igneous Rock), Approx. 1" (3cm) - Pack of 12
Brand: EISCO
Obsidian, also known as volcanic glass, forms from lava that cools almost immediately upon eruption, usually into water. Despite being dark in color, obsidian is made up of microcrystalline quartz, demonstrated by sharing the hardness and conchoidal fracture often exhibited by quartz.

- Volcanic glass formed through the nearly instantaneous quenching of lava
- Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements

- Specimen comes in clear labeled and barcoded bag for ideal storage
