Unusually heavy

[Freemindedclark]

I was wondering if anyone knew what this might be. It has a silver and gold color and is rather heavy for its size.

Do a streak test.

What do I rub it on

Unglazed porcelain. I.e. toilet lid, old electric fuse, etc.

Not to be confused with the OTHER streak test where one runs naked around some public setting. Happily that one died out in the 70s.

Thanks for the clarification. Boy I would have looked dumb.

You could try both ways, just to be sure, but I doubt the latter helps with ID.

Uh Oh .... it died out?

What does it mean if it leaves a yellow streak?

Not a whole heck of a lot Freemindedclark.

Streak tests are for minerals. Minerals are a specific combination of elements with a set of stable indicators including specific gravity, crystal form, fracture and streak. A specific mineral will have an identifiable streak color that in combination with the other factors I mentioned will help identify the mineral.

What you show in your picture is a rock. Rocks are composed of several different minerals. Those different minerals in combination do not produce an identifiable streak nor do the other identification tests I mentioned work on rocks.

What you are showing in your picture is a rock type often called mica schist. The mica is the sparkly part. Schist is not a group of specific minerals it's a description of a class of rock based on how the rock was formed. Schists are very common metamorphic rocks that have as many different minerals and forms as there are schist deposits. Rocks are like that - different wherever you find them.

The silver and gold colors are due to the refraction of light through the thin plate like crystals of mica. Mica in it's several forms is a common silicate and has no commercial value unless the mica crystal plates are very large (inches).

Thank you very much for the indepth response. It's cool that you took the time to explain things the way you did.

Good eye. I could not make out what we're dealing with from the pics.
