During World War II, Germany invented a new method of merging metals. The technique, which combined zinc and chromium, made it economical enough to create another first—stainless steel cookware. Using this latest innovation in merging metals, the first stainless steel, three-ply, carbon core waterless cookware was created and sold under the name Lustre Craft. It was a huge success. However, as WWII waged on and the American military entered the fight, production of cookware came to a halt. All manufacturing facilities were repurposed to churn out supplies for the U.S. military. Meanwhile, the sale of the Lustre Craft and Kitchen Craft cookware continued to soar. The sales team had to tell customers, “You’ll receive your cookware when the war is over!” Most of these customers were from the abundance of single women now working in factories, supporting the war effort.
