Learn MoreA mineral's streak is the color of its powder when the mineral is rubbed on a square of porcelain called a streak plate. Streak is one of the best physical properties for the recognition of metallic minerals because metallic minerals all have a very dark-colored streak that is nearly always consistent for a given metallic mineral.
