Gold will have a gold metallic streak, and Fool's Gold (pyrite) will have a greenish black streak.
What are the two best property tests to see if you have real gold or fool's gold?
One way would be to perform a streak test by sliding the sample across an unglazed tile with a little bit of pressure. Gold will have a gold colored streak and pyrite will have a greenish black streak. After exposure to flame, pyrite will have a slight sulfur smell which gold will not. == == == ==
Does mica ever make a gold streak?
No, mica does not leave a gold streak. Mica typically leaves a white streak when rubbed against a streak plate.
What happens when you rub gold on unglazed porcelain?
When you rub gold on unglazed porcelain, it leaves a mark or streak that can reveal the purity of the gold. This is because pure gold (24 karats) will leave a distinct yellow streak, while lower karat gold may leave a lighter or different colored streak due to the presence of other metals. This method is often used in assays to test the quality of gold. Additionally, the unglazed porcelain provides a rough surface that helps in making the streak more visible.

Pyrites are shaped more like crystals while gold tends to form as a nugget. Another difference between the two is that gold can be scratched with a pocketknife while pyrite cannot be scratched. You also can use the malleability and odor tests.
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 is a streak when it comes to talking about science?

Why does pyrite and gold leave a streak but Quartz does not?
Pyrite and gold leave streaks because they are softer than the streak plate, allowing fine particles to be left behind. Quartz is harder than the streak plate, so it does not leave a streak when rubbed against it.
