Great question! The streak color of a mineral is not always the same as its external color, but it is consistent for each mineral, making it a reliable identification tool. 🧪 What Is Streak Color? Streak refers to the color of a mineral in powdered form, usually tested by rubbing it on a streak plate (unglazed porcelain). It reveals the mineral’s true color, unaffected by surface impurities or crystal structure. 🎨 Key Points Consistent for Each Mineral: A mineral’s streak color doesn’t vary, even if its external color does. Example: Hematite can appear black, silver, or reddish—but its streak is always reddish-brown. Different from Surface Color: Minerals like pyrite (fool’s gold) look gold but have a greenish-black streak. Useful for Identification: Especially helpful for metallic minerals, which often have misleading surface colors.
Streak is the property of a mineral that is determined by rubbing the mineral on a special plate to reveal the color of its powdered form. This can help identify minerals because a mineral's streak color is often different from its external color.
