Abstract
A process of making glass beads which comprises the steps of forming a fluid medium comprising an aqueous liquid having glass-forming material therein at least most of which is dissolved in the aqueous liquid, forming drops of such fluid medium, and converting the drops to glass beads by causing the drops to travel in separated condition first through a firing zone at glass-forming temperature to cause evaporation of liquid and formation of glass from the glass-forming material, and then through a cooling zone to cause the glass to solidify.

A process of making glass beads which comprises the steps of forming a fluid medium comprising an aqueous liquid having glass-forming material therein at least most of which is dissolved in the aqueous liquid, forming drops of such fluid medium, and directly converting the drops to glass beads by causing the drops to travel in separated condition first through a firing zone at glass-forming temperature to cause evaporation of liquid and formation of glass from the glass-forming material while still within said firing zone, and then through a cooling zone to cause the glass to solidify.
