I sure do miss Dusted, don't know how his health is as he was having neck problems. I have a few friends in Tnet that are really knowledgeable about a lot of this stuff and I just ask them. Yes we really need this thread to help each other and look forward to Dusted You's return.

I am a little confused about slag now. I am no expert but I always heard that slag was manmade glass. Obsidian is different from man made slag or maybe I am wrong. If so tell me as I have a lot of slag I was told.

I have always heard of obsidian referred to as "volcanic glass", which is naturally occurring. It's black and somewhat transparent. I have a few samples and can post pictures if you like. If you do a Google search for obsidian, you'll see some examples as well. I hope that helps!
 

Thanks AuSomeness for the reply. I was reading earlier post of people digging slag out of the ground and if slag is man made then that was what I was confused about. Obsidian, yes naturally occurring but slag I have been told is man made. Thanks.

I have a five gallon bucket if any one needs a rock ( Obsidian ) .
 

I believe it is Basalt. everything I read matches the description. The only thing I can't find is the weight of the rock. But by description it would have to be light in weight

Thanks

Oh, my apologies. I am actually not familiar with slag. From what I read online, slag is "the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore. Slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals." (reference: Slag - Wikipedia, the free encyclopedia). Do you think this is what you have? Do you have some photos? I am curious as to what it looks like and what folks use it for!

I have collected slag from 1700's blast furnaces. As the ore melts the pour water in the furnace to cool the metal and all the impurities float to the top (slag) it is then broken and discarded. It is a dark greenish blue glass material. Quite neat. Very hard. I tried to polish and cut groves into a piece once. No grooves, no polish. It either scratches the surface at best or breaks in two pieces. I have made jewelry with it, i know some people use it for decorations in landscaping. It gives a sparkle to rocks or pebbles. If i can find a picture i will post it for you guys

Think this looks somewhat like a meteoric black diamond.

It is littered all along a creek bed about 30 feet from the furnace so either it is slag or some kind of freak occourance!

Oh, wow. That looks remarkably similar to Obsidian. So much so that I may have to re-examine my specimines just to be sure.

I guess theoretically it is close to identical. It is melted rock! Just one is natural
 

Slag from a chrysocolla mining operation in New Mecico._MG_2092.jpg

Slag can resemble obsidian
 

This one I found today. Can't seem to find an example of it anywhere except this one woman on this site posted a pic of this rock, and (to me) it looks pretty identical. It's lightweight, bout..less than an inch long, hammer won't break it. and hammer with screwdriver only leaves a very small dent. (I know, probably not my smartest move, but there it is). Both her and I are hoping it's silver. rock 1.jpgRock 2.jpgRock 3.jpg

you may be right. Just looked up pics of "melted aluminum" and saw a few pics that looked like mine.
