I thinking its slag. But not 100 percent sure. How is the relative weight for its size? Is it heavy or is it lighter in weight relative to its size?

Lighter. Which all the slag I find weighs a million pounds lol

Ya know folks, I gotta tell ya, I've spent the last 4-5 years educating myself in the fields of geology/mineralogy, with even a little
geo-chemical morphology, so I'm able to, more or less, to I D a few different rocks and minerals, but what really helps,
is when, along with a good, somewhat up-close photo, outdoors in daylight(but not DIRECT sunlight) and then some basic info
concerning where and how it was found. I don't need or want exact cords, for example; If you were 10 miles from a groomed gravel
road, on BLM land, in Washington state, and you were on a trail at the foot of Mt. St. Helens, well then yes, it's prolly an odd basalt, or conglomerate, but
if you found it walkin along some railroad tracks 10 miles S. of Pittsburg, PA. Well then it's prolly some sort of melted, industrial
train wreckage. Knowin some of the circumstances of how and where you found it, helps ALOT!, so that one can narrow it down to
the couple most likely suspects if not peg it exact. It also helps a lot if you can cut or sand a small "window" on one side b'cause
when a rock or mineral lays on the ground, exposed to atmosphere and rain, ice, and changing temps. it becomes chemically weathered, and altered.
I have many different rocks, that once sliced open, sanded and polished, look nothin like their exteriors.
And I just need to let folks know that if'n ya'll want help with an ID, please try to provide a little more info. along with a decent photo, fer not
just me, but any body here that will help you ID something, Ok? Coolbeans!

Sounds familuar.. I've said the same thing a few years back.. But I like the way you put it RH. Although I don't do the extreme testing to ID what soemthing is and I tend to limit myself to just a few stones/crystal IE Amethyst, Chalcedony, Agate etc.. bucause in my field of study.. those who can actually use the lease amount of stones within their practice.. tends to stay within themselves and what they know.. Meaning, I doubt I'll ever use or actuall find a use for soem of these odd ball stones I come across.

Hey SW, now I don't know that I'll do any "extreme testing", that would require the purchase of a used, re-furbished SEM, and those run about 20k, but an amateur rockhound can do a
handful of things on his (or her) own and the few tools are NOT expensive, here man, go here and check this out.
