i have no idea..... but its probably a no .. take my advice.
The mineral graphite is soft enough to leave a mark on paper. We use graphite, which is a form of carbon, as pencil lead. And it works pretty darn well at leaving marks on paper.
The same color as the writing from a pencil, very dark grey or black. Pencils used to be made of graphite
Those minerals that are harder than the unglazed porcelain streak plate will scratch it rather than leave a streak.
Shale is a type of rock, not a mineral. Streak is used to help classify minerals. It can leave a streak, but it doesn't mean anything.
It leaves a brown streak.
Graphite is a mineral that does not leave a clear streak.

Graphite
A streak of graphite is the mark left on a surface when graphite is rubbed across it. It is typically a shiny, metallic gray color. Graphite's streak is often used as a diagnostic property to help identify minerals.

White, but i have no idea why or how, it is used in white pencils replacing graphite and is used to write on black paper
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.

The Streak Is White.
It doesn't leave a streak.
Some minerals are harder than a streak plate and will therefore leave no streak or the powder of the ceramic streak plate.
Diamond will not leave a streak on a porcelain streak plate because diamond is harder than the streak plate. It will leave a scratch on the streak plate for the same reason.
