Natural History (Pliny) developed for counterfeit coins and proved very popular with the victims, mostly ordinary people. He deals with the liquid metal mercury, also found in silver mines. He records that it is toxic, and amalgamates with gold, so is used for refining and extracting that metal. He says mercury is used for gilding copper, while antimony is found in silver mines and is used as an eyebrow cosmetic. The main ore of mercury is cinnabar, long used as a pigment by painters. He says that the colour is similar to "scolecium", probably the kermes insect. The dust is very toxic, so
Metal-induced crystallization on some area of the a-Si. Upon annealing, crystallization starts from the portion of a-Si which is covered by metal and proceeds laterally. Unlike MIC process, where metal contamination in the obtained polysilicon is relatively high, the laterally crystallized silicon in MILC process contains very small amount of metal contamination. The crystallization speed is low, but is adequate for applications such as fabrication of thin film transistors. In this case, metal is deposited on the source/drain area of the transistor and the channel is laterally crystallized. It has been also shown that applying an electric field increases the speed of
