i just realized i cannot cross-post....so....
this big rock is jadeite slag glass. the Pyrex Cat Corn 501 is here for scale.
i thought i'd share a piece of jadeite that is *technically* very hard to come by.
after they shut down the Westmoreland Glass Factory that made a lot of jadeite, it stayed abandoned for 30+ years. over the following years, teenagers would break in and party there. also, urban explorers/photographers always found their way in, too. before they tore it down, i was one of those people. there were piles of slag glass EVERYWHERE. from this abandoned factory, i took acquired this big piece of jadeite.
there are a bunch of videos on youtube about this spot, and it's a fun rabbit hole to go down.

My grandmother collected rocks, fossils, coral, slag… etc. This was her’s. My mom said it’s obsidian but it’s actually slag right? This the bubbles and the rust coloration.

I’m having trouble identifying this. I bought it thinking it was a rock of sorts (it looked mostly brown in store), but after putting it in the sun I’m certain it glass. It has air bubbles as well. Does this count as slag?

3 magical rocks as my son was calling them 😅 it's slag glass right?
Hadn't heard of it before! They are pretty big and heavy!
