A lot of homes are painted deep red. The paint originated from the copper mine at Falun in Dalarna, Sweden which operated since the mid-13th century and closed in 1992. Extracting of copper and gold from the Great Copper Mountain is believed to be the oldest still-existing enterprise in the world.
The paint consists of water, rye flour, linseed oil and mine residue which contain silicates, iron oxides, copper compounds and zinc. The actual colour differs depending on how much the oxide is burnt. You also see a dark green colour, Falu Grön which has been produced by mixing black and ochre.
Falu red is effective in preserving wood and remains a popular choice.
