Most commonly, volcanic glass refers to obsidian, a rhyolitic glass with high silica (SiO 2) content. [7] Other types of volcanic glass include the following: Pumice, which is considered a glass because it has no crystal structure. Apache tears, a kind of nodular obsidian. Tachylite (also spelled tachylyte), a basaltic glass with relatively low ...
Obsidian (/ ə b ˈ s ɪ d i. ən, ɒ b-/ əb-SID-ee-ən ob-) [5] is a naturally occurring volcanic glass formed when lava extruded from a volcano cools rapidly with minimal crystal growth. It is an igneous rock . [ 6 ]
Glass Mountain, in Inyo National Forest, is one of the tallest peaks in Mono County, California. The peak lies 20 miles (32 km) southeast of the shoreline of Mono Lake and is the highest point on the four-mile (6.4 km) long sinuous Glass Mountain Ridge. [3] [4] [5] The Glass Mountain Ridge forms the northeast boundary of Long Valley Caldera.
Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently.

Rhyolite (/ ˈ r aɪ. ə l aɪ t / RY-ə-lyte) [1] [2] [3] [4] is the most silica-rich of volcanic rocks.It is generally glassy or fine-grained in texture, but may be ...
The glass shards (mostly brown) sometimes become welded together when the deposit is still hot, and can be deformed by flow and compaction about crystal fragments (clear). Ignimbrite is primarily composed of a matrix of volcanic ash ( tephra ) which is composed of shards and fragments of volcanic glass, pumice fragments, and crystals.
