摘要:
A leadless glaze composition having properties that make lead oxide containing glazes so widely used as ceramic glazes. The glazes according to this invention are prepared to analyze more than about 0.53 to about 1.5 weight percent molybdenum trioxide with the source of the molybdenum trioxide either in the frit or as a mill addition being alkaline earth molybdenate, for example, calcium molybdenate (CaMoO.sub.4).
摘要:
A method and system for quenching, drying, and elevating glass compositions comprising an incline reciprocating conveyor arranged to receive a stream of molten glass. The reciprocating conveyor has deep side and lower end walls in order to hold a pool of quenching liquid which is constantly replenished. The reciprocating action of the incline conveyor moves the quenched and shattered glass up out of the quenching pool to the higher end of the conveyor where it is drained and then delivered to a second conveyor. The second conveyor preferably comprises a helical vibrating conveyor surrounded by infrared heaters. The infrared heaters can be adjusted to supply just enough heat to the shattered glass on a helical vibrating conveyor surface to provide drying of the glass.
