Pink glass plates made in octagonal shapes are known as depression glass. Two dinnerware manufacturers, Heisey and Anchor Hocking, made square plates in an octagonal shape in a light-pink color. Heisey issued octagonal flamingo-pink plates between 1925 and 1937, while Anchor Hocking Mayfair plates date between 1931 and 1937.
Depression glass is the name given to glass dinnerware made by several companies during the Great Depression era. In addition to pink, this dinnerware comes in other cheerful colors, such as amber, cobalt blue and green. Depression glass was mass-produced and quite affordable at the time. Consumers could purchase a plate for about the same cost as a loaf of bread.
