Abstract
The present invention relates to a process and apparatus useful therein for steam hydrating alkali silicate glass materials and subsequently extruding the hydrated material. There need be no moving parts in the hydration apparatus since the process can utilize the pressure of steam to both hydrate the glass and extrude it from the hydration chamber. The process permits the formation of solid extrusions or foam extrusions.
