Among the industrial establishments of the city are stove and range factories, flour mills, rolling mills, distilleries, breweries, shoe factories, copper refining works, nail and tack factories, glass works and agricultural implement factories.
Other thriving trades include the glass-works on the shore, pottery-works in the "auld toon," dye-works and a factory for the making of electrical appliances.
There are cloth, artificial flower, and cigar factories, glass-works, potteries, and in the neighbourhood large granite quarries.
The glass-works of Fourmies date from 1 599, and were the first established in the north of France.
The trade is chiefly connected with the produce of the neighbouring coal-mines and that of the numerous important iron and glass works of the district.
