ABSTRACT:
A method and apparatus for manufacturing spheres from molten material, such as glass, by allowing drops of the molten material to pass from one end to another of a column containing a liquid, such as a mixture of salts, the temperature of the column being so graduated that the drops harden during passage through the column. The column can be bifurcated at the lower end into legs provided with cooling cuffs for alternate use.
