All brand labels have been whited out. This photograph was grouped together with those of the Owens-Corning Fiberglas Company Plant, so it is reasonable to assume that they are somehow related. Fiberglass was invented by Owens-Illinois, and merged operations with the Corning Glass in 1938. Mineral wool, mineral fibres or man-made mineral fibres are fibres made from natural or synthetic minerals or metal oxides. The latter term is generally used to refer solely to synthetic materials including fibreglass, ceramic fibres and rock or stone wool. Industrial applications of mineral wool include thermal insulation, filtration, soundproofing, and germination of seedlings. View on Ohio Memory.
