The Conquest of New-France put an end to pottery imports from France, and opened the door to British imports. However, in the same circumstances, local pottery production experienced a boom which culminated in the middle of the 19th century, as several large manufactures sprang and developed along the St. Lawrence. The most famous of these was Dion Pottery, which dominated the artisanal pottery market in Québec for several years. The Dion family ran operation was one of the last manufactures to operate in the traditional hand-made way; as cheaper industrial productions took over the market, the company had to close its doors. During the 20th century, there was a renaissance of ceramics in Québec through Beaux-Arts schools and technical schools such as the École du Meuble.
