 In the nineteenth century, watercolours began to be industrially produced in tubes and a "Chinese white" tube was added to boxes for this purpose.Gouache tends to be used in conjunction with watercolor, and often ink or pencil, in 19th-century paintings.Later that century, for decorative uses "poster paint" (as it is known in the U.S.), was mass-produced, based on the much cheaper dextrin binder.
