Tinned steel gave way in the latter half of the 1900s to enameled steel, which was the most popular cookware in America from the 1870s and into the 1930s. 1870 was when the COLORFUL, speckled, spattered, marbled, painted with designs, cookware appeared. "Agate" ware and "Graniteware" were the most popular, but the stuff is very collectible today and some unusual pieces can sell for ridiculous prices.
Two years ago a red enamel muffin tin with bright blue speckles, sold for $1685.00. Original price in 1889 - 15¢!
Some manufacturers hung on for a few years making larger pots which were much less expensive than aluminum or stainless steel and the ubiquitous turkey roaster with it's iconic domed lis and available in many sizes. Dishpans were another item that hung on until pushed aside by plastics.
