Document Summary

A lot of impurities. they come out of volcanoes, thus found far from origin: flint has a periodic atomic structure. Colours change because of impurities: re > int + iron . Bellspark, one of the most common materials, it melts and penetrates. China was into ceramics while europe was into iron/metals. Temperature = a numbered scale develop for heat, it is just a measurement. Clay helps you shape the object you store. A full pit kiln = uses oxygen as fuel. Irons in mountain gets oxidized to iron oxide. Base center cubic > copper, silver,led,bronze and gold !if you don"t know just guess this! Gold, silver and copper are the 3 metals you can nd in the nature in its native form. Native metals = you nd them on the ground, you can use them. Furnace&kiln = tech used to develop high temperatures. Slag = waste byproduct created during smelting. Metallic age started when people started to use smelting.
