Glass

Title

Glass

Subject

When magma is quenched (cooled exceedingly rapidly) even very small crystals are unable to grow. Instead, a volcanic glass is formed. It is amorphous (having no crystalline structure), and is consequently isotropic.

Description

Have a look at the rhyolite glass (L113) in the 1A Reference Series.
