Abstract

1,130,284. Glass bead compositions. GENERAL STEEL INDUSTRIES Inc., [trading as FLEX-O-LITE DIVISION]. 11 April, 1967, No. 16624/67. Heading C1M. A glass bead composition has a refractive index of above 2À0 and consists essentially in percentages by weight of PbO 48-65; TiO 2 19-41; alkaline earth oxides, preferably BaO, 0-8; B 2 O 3 0-5; ZrO 2 3À8-13, the composition containing boric oxide and/or an alkaline earth oxide. A number of examples are given, with colours ranging from light yellow to dark brown. The beads may be in sizes ranging from 325 mesh up to 20 mesh and are made by conventional methods as disclosed in the following U.S.A. Specifications 3,150,947; 3,148,045; 2,965,921; 2,838,408; 2,790,723; 2,600,963; 2,334,678; 1,174,224.
