Colour Mills - An Ardennes tradition

According to a 2009 Conseil Regional de Champagne-Ardenne (the Council for the regional development of Champagne-Ardenne) study, colour milling was traditional in the Ardennes right up to the first quarter of the 20th century.

Mills were located in the centre part of the departement. Out of nine mills, only one, Le Moulin à Couleurs in Ecordal, still exists and is still active. It is the only one of its kind in France.

Their activity consisted in grinding local materials such as iron bearing clays and slate as well as minerals extracted outside of the departement, such as Burgundy Ochres or minerals that were imported from abroad, such as iron from Madras in India or lignite from Cassel in Germany, for the production of pigments and oxides.

Les Vernis Boizet - A family firm

A colour mill was established in 1866 under the name "Les Vernis Boizet" by Désiré Boizet and J.B Courtois in the small village of Ecordal, in the southern part of the Ardennes.

They were producing colouring pigments from natural earths which were mainly used for the manufacture of varnishes.

The firm stayed in the Boizet family until 1992 when Jean Boizet retired. "Les Vernis Boizet" were then sold off to Le Moulin à Couleurs.

In 1996, Le Mouling aà Couleurs acquired Les Etablissement Lechiche, a firm from Auxerre in Burgundy and was thus able to widen its products'range. They now provide a palette of 85 different colourants.
