Six generations of Americans have been using Granite Ware canners to preserve fruits and vegetables. The dark porcelain surface and steel core absorbs energy and evenly distributes heat to the contents. The construction is porcelain fired at 1500 degrees to the carbon steel core. The result is a canner that heats rapidly. The canner is perfect for preserving tomatoes or fruit, processing 8 quart jars at a time. Easy to clean. Comes with rack for easy lifting jars from canner. Granite Ware's high efficiency, quick boiling performance combined with its modest cost make it ideal for canning. Holds seven quart jars.
