A streak plate, or unglazed white porcelain tile, is used to perform streak tests which can help to identify minerals. Rubbing the mineral on the streak plate will finely powder it and reveal the color of the powder, which in some cases is quite different from the color of the mineral. Eg: hematite is black but has a red streak - a good way to tell you have hematite instead of one of the many other shiny black minerals.

Why do gold and pyrite leave a streak but quartz does not?
Gold and pyrite leave a streak because they are both metallic minerals, which means they can rub off on a streak plate, leaving a colored line that reflects their metallic composition. In contrast, quartz is a non-metallic mineral with a hardness of 7 on the Mohs scale, making it too hard to leave a streak when rubbed against a streak plate. As a result, quartz typically does not produce a streak.

What would you expect to happen if you rubbed a mineral of hardness 7.5 against a piece of quartz?
If you rubbed a mineral of hardness 7.5 against a piece of quartz, which has a hardness of 7, you would expect the harder mineral to scratch the quartz. The mineral with a hardness of 7.5 would leave a mark or scratch on the quartz surface, demonstrating the principle that harder materials can scratch softer ones. However, quartz would not be able to scratch the harder mineral in this scenario.
What happens if you rub the mineral across a streak plate but the mineral does not leave a streak?
