When a mineral is rubbed on a piece of unglazed porcelain, it leaves a streak of finely powdered material. This streak may have a different color from that of the mineral itself and is an excellent check in identifying many minerals. Hematite, the common iron ore, invariably has a red-brown streak. Some minerals are very soft; others very hard.
