✦ Synopsis

melted--the 6000°F. required to :melt tungsten is higher than any substance which might be used for a container.

By chemical means the oxide of tungsten is recovered from the ore and heated in an electrical furnace with hydrogen gas. The hydrogen and oxygen combine, leaving tungsten powder which is pressed into bars. The bars are subjected to a heavy electrical current, raising the temperature of the tungsten to a point where it fuses into a rod.
