White. All forms of quartz will have a white streak, regardless of specimen color.
Is streak colour always the same?
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.

What you find when scratch a mineral over an unglazed tile?
What you are referring to is called a streak test. It's used as an aid to mineral identification. As a mineral is drawn over the unglazed tile surface, it is reduced to a streak of dust which reveals the true color of the mineral. If no color is revealed, the streak color is called white.

No, that is called the streak of a mineral.
What is more reliable than color as an indicator of a mineral's identity?
The crystal structure and composition of a mineral are more reliable indicators of its identity compared to color. Color can vary due to impurities or environmental factors, whereas crystal structure and composition are more definitive characteristics that help in identifying minerals accurately.
