rare
leland blue
iron-smelting slag

The tell
Glassy blue-grey, often shot through with bubbles or frozen froth. It is not a rock. It is iron-smelting waste from the 1870s.
Man-made, and that is the appeal rather than a mark against it. Leland and Fishtown are where it comes from, and it is finite: nobody is making any more.
