In 1958, nothing of the sort exists in the French pottery ; Jean Cocteau invented this pencil to give his designs an appearance of pastel.

Orphée à la lyre
Liquid clay called "Barbotine" to which metallic oxides are added, giving it its colour during the baking process. The mixture is applied on the surface of a piece of unfired clay. The slip can re-cover the piece to make a background or can be re-engraved to find the initial colour of the piece.
