Røros Museum. Melting Shop
The second part of the museum is a real metallurgical shop, founded in 1646.
The picture above the entrance shows what the factory looked like in 1888.
Copper ore was fed from the mines to the furnace charge yard of the smelting factory.
In addition to ore, quartz was also stored here, which removed iron from the melt.
Fuel was wood, which was harvested in the surrounding forests.
All transport operations were done manually, workers delivered materials to the furnaces on a stretcher.
The model of the smelting factory.
The melting furnace was constructed of layered natural stone.
Loading the charge into the furnace.
Exhaust openings of the furnace. Through the upper merged easy slag, heavy copper came out through the lower.
The main tools of the metallurgist are a wheelbarrow and a shovel.
The smelting furnaces were located along the river, which served as a source of energy for the drive of mechanisms.
On the river was a dam, where the water was supplied to the wheels on wooden trays.
The wheels rotated the crank mechanisms that set in motion the furs, inflating the air into the melting furnaces.
Carefully made models of mechanisms and now work on the energy of water.
The metal and slag merged into cast-iron ladle carts, the slag was taken to the dumps, the metal went to the foundry site.
In the corner of the shop there is a small metallurgical laboratory, here the quality of copper was estimated, and now the souvenir bars are smelted.
These bailers poured molten metal into molds.
Copper went to customers in these bars.
Products were weighed and carefully considered, copper was a very expensive commodity. Cannons and Church bells were cast from it, rolled sheets for covering roofs, which in some places are already 300 years.
Over time, wooden overpasses were replaced with concrete ones.
Mechanical loading devices appeared.
I worked in the copper smelting industry, and I want to say that my fatory is not much different from what I saw here.
The company worked until 1953. Now only the lower parts of the furnaces.
Pieces of solidified metal is removed from furnace stopped.
Unique photos of the late nineteenth century.
Copper spill site. Round barrel on the tracks is the mixer, which receives the melt of the desired composition.
As you can see, in those days there was no special clothing, workers did not have any protective equipment, even helmets. I am familiar with the work of modern metallurgists, even today it is dangerous and hard physical work in extreme conditions.
The graphs show the performance of the company for more than three centuries.
The museum has a small collection of household items of miners and metallurgists.
