Anatolia is a source of both obsidian and corundum. Corundum (also known as carborundum, or emery) is a grinding and polishing material and although very hard (no. 9 on the Mohs hardness scale in which no. 10 is the highest value), it is easy to work in mineral form. Obsidian objects were among early exports from Anatolia, and they were used for spears, arrowheads, knives, axes, scrapers, and jewelry. It is reasonable to conjecture that mirrors were also exported from there. Conolly suggests the first shaping/grinding of an Anatolian mirror surface was quite coarse; the surface was then polished with a fine-grained material such as silt and buffed with material such as leather.
