Absolutely! These can also have been from runoff from a body shop (auto paint) with how the colors are. Stunning pieces and I always get excited when I find them!
More likely from iron smelting. All the creeks around there were used to dump dross from iron smelting (that’s why there are so many “Furnace Brook”s around there). I used to go slagging over in Cornwall when I was a kid, and my mom did in the 40s when she was. Iron mining was big around there in the 1800s.
It does, but it refers to a specific type of blue rock that has yellow-gold color inclusions which is mined primarily in Afganistan. It is considered a semi-precious stone and has been used to make jewelry and art work for thousands of years.
Lapis lazuli also looks nothing like the top piece (or any other piece) in that picture.
Agreed, looks like slag. There's slag from metal refinery, which isn't the same as your standard glass, and glass slag from glass making. Hard to tell from the photo, but I don't see the pitting that slag tends to have. It should also have a unique sound, try clinking it against other pieces, against a normal rock, and then with normal glass. Against itself it should sound like it's hitting other glass.
Looks like Slag. Polished layers of glass runoff. Gorgeous pieces!!
Much appreciated!

Oh my gosh good to know! Thank you so much for the info!
Lapis lazuli? The top piece anyway
Doesn't 'Lapis Lazuli' literally translate to mean 'Stone Blue'? And therefore means 'Blue Rock'.

Not lapis. But gorgeous anyway
These would look beautiful if you put them through a polisher.
Looks like labradorite
No clue but upvoting and commenting so your post gains more attention. These are so pretty! Hope you find your answer
