The hydraulic power produced by the water of the Bisten enabled the blowers to be put into action to increase the temperature in the furnaces. The iron industry flourished until the revolution, which stopped this activity. In 1814, François Payssé revived the iron and steel production.
The blast furnaces were shut down and only the cast iron casting remained. The Quinchez family took over the running of the company. Finally, in 1929, the factory was directed by the Schmitt brothers.
