Man, first instinct; woah. I'm legitimately surprised I still remember. :P

I don't think we HAVE have to know them, but I'd put them in a binder or stuff so that if you get asked, you'll have the info.

My turn...I guess.

What is this specimen and what is its most special characteristic?

Ulexite, and whenever you place it on top of something, it shows up on the top surface?

Nevermind, Cherrie_Lan is right. The fibers are parallel to each other.

You're both right....as in, @Cherrie_Lan is right; it's Ulexite--your turn!

Also, I'm LOVING how active this thread is!

Just saying, this is science olympiad, not pseudo-science olympiad. They will never ask for 'healing powers' on a test (unless it's a REALLY bad test), although you can find it for every mineral if you look for it. Try to keep the pseudo-science off of the forums please.

Garnet is NY's gemstone. It is mainly used as an abrasive; in the US, it is mostly used for waterjet cutting. It is good for this purpose because it is hard (6.5 - 7.5 Mohs scale) and has sharp edges when broken for sanding and cutting. Occasionally used for filtration due to small pores/high specific gravity.
