vegasjames look at this second rock... makes me think....
Does that second one attract a magnet? Makes me think of some meteorite photos I have seen. the outside is brittle like a crust?
both very interesting.

vegasjames look at this second rock... makes me think.... the first resembles some of the amygdaloidal basalt I find here, as it ages it turns blue and some of the filling in the pockets fall out. It can also have vesicles and inclusions as this piece seems to have. Then again it could be something completely different (especially since it seems to have been a 'loner')
Does that second one attract a magnet? Makes me think of some meteorite photos I have seen. the outside is brittle like a crust? but inside more solid? are the patterns in the black matrix from your saw or part of the rock itself?
both very interesting.

They both look like basalt. I am quite sure the first one is vesicular volcanic basalt. I have collected stuff that looks exactly like it here in the Idaho volcanic areas - ranging in color from black, red, white, blue, and even green. It was examined and explained to me by a geologist that it is actually an extrusion or even airborn expulsion from the volcano so that the air comes out of solution in the melted rock and the rapid cooling traps the gas. It is not super light like pumice, but rather quite dense. Sometimes the holes are filled with small white agate accretions which look cool.
Anyway, that is my guess.

Interesting. Second one reminds me of a meteorite. Hope it is!

That second one looks a bit like Goethite. Both are really nice specimens.

I thought the first one was extraterrestrial... Then my brother said the first one could be a petrified Boeing bomb..He said it looked like a piece of corn stuck in it in the first pic..I told him it was space corn..LOL...

The first one looks like slag to me. It's a by-product of smelting. We see a lot of this in Michigan. It's very pretty, but doesn't tumble well. I've found it in blue and green, sometimes gray or purple. Where did you find this? (I can't upload my photo. The error says the forum has exceeded it's upload limit. :/ )

I was thinking slag, too. Actually, slag from MI since I have seen so many pix of it right here at RTH. You have to host your pictures somewhere else and post the link here. Try flickr or photobucket. You can use the photo button (above) to paste in the url and then you're good.

#2 could be ferro-silicon, can you check specific gravity?

#1 is classic slag glass, agreed.

I'm with the slag idea too. Before the EPA took complete control of our lives, many smelters would take dump truck loads of their unwanted slag & dump it in out of the way places.

For #2: Streak? If it's as slightly orangish-red as the pixs on my monitor, possibly breithauptite.
