Manufacturers of Porcelain Enamel.

Porcelain enamel is a mineral substance; the properly proportioned mixture of silica, borax, soda, zinc oxide, and other minerals. These ingredients are first reduced to a molten mass in a high temperature smelter, then later fused into a metal base at a heat of 1550 degrees. Being completely mineral, and backed up by sheet iron or cast iron, porcelain enamel is acknowledged to be the most durable finish known to man.

Has product images, description and applications to provide product details.

Unbound from a large rare 1939 Process Industries Catalog, this unique old one-page technical brochure would display beautifully matted and framed. Nice graphics. A fabulous addition to your retro industrial equipment library.
