Appearance, Uses and History
I’ve written quite a lengthy article on slag here; there is no sense in me posting the same information again! 🙂
Slag often looks like a black volcanic rock similar to scoria, but can be glassy and multicoloured too! It is purely an industrial byproduct but can be interesting or attractive.
Anywhere with a history of industry. 90% of the UK and probably most of the rest of the world.

Hazards and Warnings
Almost all rocks, minerals (and, frankly, almost all other substances on earth) can produce toxic dust when cutting, which can cause serious respiratory conditions including silicosis.
When cutting or polishing rocks, minerals, shells, etc, all work should be done wet to minimise the dust, and a suitable respirator or extraction system should be used.
Slag and clinker may not translate well into other languages. If you know of more appropriate words please let me know!
