The glass then is permitted to cool at a predetermined rate until its temperature passes the "'strain point "'( ? = 10 14.5 Poise ), below which even microscopic internal flow effectively stops and annealing stops with it.

Schistosity and gneissic banding ( the two main types of foliation ) are formed by directed pressure at elevated temperature, and to interstitial movement, or internal flow arranging the mineral particles while they are crystallizing in that directed pressure field.
