Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt
From German Tachylite, from tachy- + Greek lutos soluble, melting

Available in Lots of Colors and Patterns, Clasts are smooth to touch
Tachylite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
