Glass‐like materials containing carbon were produced by heating plumbite‐treated cotton fabrics in a limited oxygen atmosphere while in contact with a surface having a high silica content. Although the new materials were changed to a clear glassy state, they retained the design and shape of the fabric weave and were hard, brittle, acid resistant, and alkali resistant. Surface smoothness of the new materials and release from the high silicon‐content materials on which they were made depended on lead content of the plumbite‐treated cotton fabric. High lead contents produced smoother surfaces and better release. This information was applied in producing glass‐like write‐on labels for laboratory glassware or individual flakes of the new material. Direct heat from a Bunsen‐type burner caused the new glass‐like materials to become metallic gold in color without altering other properties. Indirect heat reversed the color to the original. ESCA and x‐ray fluorescence examinations showed the atom ratio of lead to silicon to be 2.5:1 for those made from high lead‐content fabric. Substantial carbon was present in all lead levels.
