Cinnabar akin to that of HgO: each Hg center has two short Hg−S bonds (each 2.36 Å), and four longer contacts (with 3.10, 3.10, 3.30, and 3.30 Å separations). In addition, HgS is found in a black, non-cinnabar polymorph (metacinnabar) that has the zincblende structure. Cinnabar generally occurs as a vein-filling mineral associated with recent volcanic activity and alkaline hot springs. Cinnabar is deposited by epithermal ascending aqueous solutions (those near surface and not too hot) far removed from their igneous source. It is associated with native mercury, stibnite, realgar, pyrite, marcasite, opal, quartz, chalcedony, dolomite, calcite and barite. Cinnabar is
Wooden toymaking in the Ore Mountains Wooden toymaking in the Ore Mountains The history of wooden toymaking in the Ore Mountains is closely bound to regional circumstances. The Ore Mountains are located in Central Europe on the border between Germany and the Czech Republic. For many centuries it was a countryside in which the local population eked out a hard existence from the land. Long and harsh winters restricted agriculture; in addition the region had very poor communications. With the onset of ore mining a new line of commerce developed, but the hard labour and high risks involved meant that it was only work for young
