Hi,
I’m new to this site and a relative newcomer to the art of lapidary. Been doing it for a couple of years now.
I have have been given some Slag Glass rough by my granddaughter. She and her family picked it up in New York State. I would like to make her something from a piece. Can I cut and polish slag like a typical stone? I would hate to ruin a blade on my trim saw or worse a wheel on my Cab King.
Any my advice would most welcome
Thanks, Doug

Welcome from Virginia! Yes, you can use glass the way you use a rock. Obsidian is glass. It works up very well. Just don't cut yourself.

Welcome to the forum!
rockjunquie is right. It will cab up just fine. I just wouldn't start it out on your 80 grit. It will chip like crazy on that coarse of a wheel. Use cerium oxide as a final polish.

Welcome simplystones! As the others said slag glass is workable along the lines of obsidian ... *but* ... it's worth mentioning that it depends on why you want to polish it in the first place. I've collected some slag material down south of Tucson that was nick named fire slag because the surfaces had a beautiful iridescent water-meets-oil sheen that would flash when tilted in the sun. Polishing on that material was impossible because you'd immediately go through the color layer and end up left with a lump of coal.

Welcome! Not everything needs to be super shiny. Lots of beautiful slag glass in the world.

Didn’t know if the more corse wheels would leave scratches that need to be polished out like typical cabochons of rock.

Hi Doug, welcome to the site. There's a slag glass here in Michigan that sells for big bucks. It's called Leland Blue and is very popular.
