▪ chemistry and industryvessel used for distillation of substances that are placed inside and subjected to heat. The simple form of retort, used in some laboratories, is a glass or metal bulb having a long, curved spout through which the distillate may pass to enter a receiving vessel. The design dates back to the cucurbit (flask) used by medieval alchemists.Large retorts are widely used in industry in separating gold from mercury in amalgams, in separating zinc-metal vapour from the smelted ore mixture, and in obtaining coke or gas from coal. Industrial retorts may be tall and thin or short and wide; some are of clay and some of iron.* * *
