What is Meudon white?
Blanc de Meudon is a white powder made from chalk, extracted from quarries dug in this eponymous town of Hauts-de-Seine, in the Paris region.
Refined, this product, consisting mainly of calcium carbonate, was sold in different forms: in particular molded into loaves or loose in bags.
It was intended for industrial or household use.
Since the closure of the factory and the quarries in the early 1920s, the white of Meudon – which has kept its name – now comes from other French or European quarries.
