On Rock Glass, and the Solid and Liquid States

Extract

The solid and liquid states are defined on the basis of the viscosity-temperature curve.

Glasses are amorphous solids. Their state of molecular aggregation is fundamentally different from that of liquids: they are not super-cooled liquids.

It is suggested that porphyritic texture may result from an even rate of magmatic cooling on account of the abnormal increase in viscosity which occurs before vitrifaction.
