Glass Wool: Steam-Blown from an Electrically Reheated Glass Stream (Slayter, US 2,133,235)
Very fine glass wool needs very hot glass at the blower, but a stream loses heat on its way out of the furnace. Games Slayter of Owens-Illinois (filed 1933, US 2,133,235) reheated the stream as it left: it runs through a silicon-carbide element lined with platinum, then a steam blast draws it into fine filaments, which a conveyor carries under a roll that presses them into a loose mat.
Not given: the glass, any temperature, the current, the steam pressure and the sizes.

Feed it to the bushing
Feed it to the bushing
The refined glass flows along the forehearth, an extension of the furnace, to a well in its floor. A refractory bushing is held under the well by a ring. Raise or lower the refractory plug in the glass above the bushing to set the flow.

Reheat the stream
Reheat the stream
The bushing carries a silicon-carbide element (Slayter used "Globars") with a hole through its middle and an arm on each side, cabled to terminals. A layer of platinum spun onto the inner surface keeps the glass off the element. Pass current through the element and the platinum: the glass is heated again as it runs through the hole, so it reaches the blower hot enough to blow very fine wool without overheating the forehearth.

Blow it into filaments
Blow it into filaments
Let the stream fall through a steam blower fed with steam by a pipe. The blast draws the glass out into fine filaments.
