The museum is located in an 1823 glassworks, the only one of its kind in Europe to be completely restored and preserved almost in its entirety. This building of typical industrial architecture has a vast hall that still houses two pot furnaces, tools and manufacturing equipment. Bottles for the most prestigious of Champagnes were made here until 1920, when the glassworks turned to the manufacture of perfume bottles. After your visit, you can see a glass-blowing demonstration by the museum's crafstmen, who delight in sharing the secrets of their savoir-faire. As they work their magic, you'll see balls of fire miraculously turning into elegant, translucent objects.
