Due to the discovery of the ingredient kaolin in Saint-Yrieix, France in 1768-69, European porcelain factories were able to replicate the prized hard-paste porcelain of China and Japan. In the years following, many porcelain factories opened in the area, including Faubourg Saint-Denis in 1772. These jars, sold alone or in sets, would have stored snuff, powdered tobacco meant to be inhaled, or loose tobacco for smoking.
