MACPHERSON & COMPANY manufactures specialty glass for industrial application. This includes heat reflecting glass and composite safety glass for high hard-impact protection of operators. Various industries encompassing steel manufacturing, crane design and foundry control rooms can save money by installing high-technology glass for their industrial needs.

COBALT BLUE No. 6515 was developed for blast furnace tuyeres with the support of local steel mills. In recent years, we have supplied our Cobalt Blue for observing white-hot molten metals in Blast Furnaces, BOF’s, EAF’s, refining stations, and casters of all sizes. Typical diameters: 3/4” 1” 1-1/8” 1-1/4” 1-1/2” 1-15/16”

BOROSILICATE GLASS is thermal shock resisting and is suitable for maximum operating temperature up to 650℉

CRYSTALLIZED GLASS provides an increase of 900℉ in temperature limit over previously available heat shield glass.
