What mineral produces a black streak when rubbed on a piece of unglazed porcelain?
The mineral that produces a black streak when rubbed on unglazed porcelain is hematite. Hematite is an iron oxide mineral that typically appears metallic gray or reddish-brown in color, but its streak, which is the color of the powder it leaves behind, is characteristically black. This property is often used to help identify minerals in hand specimens.
What colored mineral has a characteristic reddish-brown streak?
The mineral that has a characteristic reddish-brown streak is hematite.

This property, along with its high iron content, is why hematite is often mined as a source of iron.
