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.
