ABSTRACT:
Disclosed is a method and apparatus for forming hollow and cylindrical ingots of amorphous or fused silica and other ingot materials. The ingot is formed from a melt on a deposition surface which is lowered as the ingot is formed at a rate which maintains a constant distance between the deposition surface and a heat source vertically positioned above same. The melt is shaped into a vertical cylinder by at least one forming tool which is a roller member rotatable about a vertical axis. In a preferred embodiment the fixed distance from the heat source is maintained with the aid of the laser beam.
