Mineral Many sulfide minerals are economically important as metal ores; examples include sphalerite (ZnS), an ore of zinc, galena (PbS), an ore of lead, cinnabar (HgS), an ore of mercury, and molybdenite (MoS, an ore of molybdenum. Pyrite (FeS), is the most commonly occurring sulfide, and can be found in most geological environments. It is not, however, an ore of iron, but can be instead oxidized to produce sulfuric acid. Related to the sulfides are the rare sulfosalts, in which a metallic element is bonded to sulfur and a semimetal such as antimony, arsenic, or bismuth. Like the sulfides, sulfosalts are
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
