What is the streak of sandstone?
Rocks are not considered to have a streak, as they may consist of several minerals. In the case of sandstone, the rock could be composed of feldspar, quartz, glauconite, and other minerals. Minerals in solutions can penetrate and stain the sandstone as well and affect the attempted streak test.
What are 2 minerals that don't leave a streak on a streak plate?
A streak plate has hardness of 7 on the Mohs scale, so harder minerals will not leave a streak. Diamond has a hardness of 10 and corundum is 9 - so neither will leave a streak.

If a mineral doesn't make a streak is it not a mineral?
