An genuine industrial experience from another century at Loos cobalt mine
The Loos cobalt is located in the middle of the village,  where you can look back upon the industrial spirit of the 18th century. The mine is surrounded by an idyllic wilderness, offering a great variation of bedrock and nature.

Several exhibitions, as well as a slideshow, can be viewed inside the mine. As you descend underground, you are led through the mine along wooden pathways and stairs, at the same time as you are taken back roughly 250 years in time, into the spirit of another century. The atmosphere will bring to mind the history of the mine, the people who worked there, and their everyday life, underground.

A short history
Some copper findings were observed as early as in the 17 th century in Los, but the amount in the samples was so small, that it was not considered worth mining.  Later, in 1733, assessor Henric Kalmeter acquired the mining rights for the mine in Los, because he suspected that the ore could contain both copper and bismuth.
As it turned out the ore indeed contained both copper and bismuth, but, more importantly, the newly discovered chemical element cobalt. Initially, the ore was exported unrefined, but the authorities found that it was a waste of time and money to have the ore refined abroad, as opposed to within Sweden, in order to extract the sought after cobalt blue pigment. Thus, Kalmeter was ordered by the crown to construct a works in Los where the ore could be refined on site, and the pigment processed. The construction was later given the name Sophiendal, and was most probably named after Kalmeters wife, Anna-Sophia.

Sophiendal was later repurposed into a glassworks. The glassworks was, however, rather short lived and had to cease production after only eight years, perhaps due to the costly and complicated transports from Loos to larger cities.
In 1751 the chemist Axel Fredrik Cronstedt discovered the ground element nickel, following examination of ore from Loos cobalt mine. However, due to a lack of new cobalt findings, the mine had to shut down in 1773, ending a 40 year long era.

The glassworks produced, among other things, the “Loosflaska”, a round bottle with a green or cobalt blue tint, that came to be associated with the Sophiendal glasswork. The few  bottles that survived to this day have an estimated value of several thousand SEK when sold on auctions.

Loos also became known  for the Loos
whetstone. People have mined shale since the middle of the 19th century in the area around Ryggskog, located west of Los. Out of the shale, people made the famous Loos whetstone. It is still made in Los today, by father and son, Dick and Conny Persson, and can be found in the gift shop at the mine, as well as other places around
the country.

In recent years
The mines were emptied of water in the 1820s and in 1923, but no ore worth mining was found during either time. In 1989, a group of local enthusiasts gathered in Los to explore the abandoned cobalt mines, which for generations had been used as a dangerous playground and dumpster by the locals. Many had wondered over the years what lay hidden under the dark surface of the water filled mines. The non-profit association
“Loosgrufvan” was founded in the autumn of 1989. The mine was then emptied of millions of liters of water, as well as hundreds of cubic meters of rock and trash. The largest shaft in the mine, more than 40 meters deep, was named ”Lovisa”. Altogether, more than 7000 hours of non-profit work were needed to transform the abandoned
mine into a tourist attraction. The mine was opened for public viewing on March 21, 1992.
