Original use
Cinnabar is mercury sulfide – HgS. This is a compound of divalent mercury and sulfur. The compound is very durable and insoluble in all acids except in aqua regia. Natural cinnabar is finely ground, very rich and clean cinnabar ore. Synthetic cinnabar is obtained with mercury and sulfur synthesis under precisely determined conditions. It has a nice red colour with a wider range of shades. In Idrija, cinnabar was obtained from the beginning of mining until 1922, with an interruption between 1658 and 1782. During all that time, 8,800 tons of mercury was obtained, which is 6.6% of the total amount of mercury obtained in Idrija. The last 400 kg of cinnabar was ground into vermilion and thus stopped its production. Samples RZ-24 and RZ-26 were, according to the inscription, obtained with a wet procedure.
Present use
The described objects are being preserved, secured and presented as important mining heritage of Idrija with exceptional universal values. They are a part of the mining collection of the Idrija Municipal Museum. Visitors can view them within the permanent museum exhibition “Five Centuries of the Mercury Mine and the Town of Idrija”. They can also be used for different types of mercury heritage promotions.
