Abstract
287,522. Quartz et Silice. March 23, 1927, [Convention date]. Drawings to Specification. Fused silica.-A method of making transparent fused silica. using quartzites of the kind referred to in Specification 190,477, consists in melting as large blocks as possible of the quartzite without deformation by packing the blocks into an electric resistance furnace with a filling of pure sand. After fusion, the cooled ingot is cut up by any suitable means and the flawless portions are separated and used for optical purposes. Other portions, which may not be optically homogeneous, are brought into shape or again treated by the methods described in Specifications 224,164.; 242,214, [Mass 60, Grinding or abrading &c.]; 270,692 and 283,174.
