Abstract: A method for producing an inorganic fiber-metal laminate, comprising bonding a ceramic fiber matrix to a metal substrate with an inorganic binder. A first side of the metal substrate is preconditioned by contacting the metal substrate with a preconditioning sol of the inorganic binder. A first side of the inorganic fiber matrix is then saturated with a binder sol of the inorganic binder. The saturated first side of the inorganic fiber matrix is applied to the preconditioned first side of the metal substrate to form a laminate. The binder sol is gelled and dried to firmly bond the laminate.

Abstract: There is provided a process for the mineralogical conversion of waste asbestos to a non-asbestos product. The waste asbestos is treated with a mineralizing agent and then heated for a period of time sufficient to convert the asbestos to the non-asbestos product. The mineralizing agent is preferably a water-soluble alkali metal borate or alkali metal silicate.

Abstract: At least two differently colored components of glass are heated to a molten, viscous state and then combined in a channel shaped forehearth to form a confluent of molten glass in which the starting components remain in discrete domains, delineated by abrupt color transitions at the interfaces between such domains. The confluent flows by gravity to a discharge end of the forehearth, at which the molten glass is fed between a pair of forming rollers which press it into a continuous, elongate sheet of variegated glass. While flowing toward the discharge end of the forehearth, the molten glass is subjected to controlled, limited stirring to break up relatively large domains of homogeneous color into a multitude of smaller randomly dispersed domains characterized by streaks, swirls and waves of individually identifiable colors.
