La Rochere
La Rochere is the oldest continuously working glass factory in Europe located
in the forests of the Lorraine and Franche-Comté regions that provided firewood for furnaces and ferns, the ashes of which made the potash necessary for the glass fusion.
In 1475 the founder Simon de Thysac, "Gentleman glassmaker", obtained permission to manufacture glasses at the "Rochiers", this is preserved in the National Archive in France. The production site is opened and the "hand made" manufacture of crystal glasses is shown and explained to visitors.
