Another interesting use for slag is starting to sprout out of France. In the north of the country where its mining and industrial industry has now been abandoned all that remains are the small mining villages and the colossal slag hills or “terrils”.

When we think about slag most of us imagine a rocky, rough, rugged material. But recently, some have polished this diamond in the rough and created something beautiful. A family in Riddells Creek, Victoria, have created an eco-friendly home which has polished e-crete slag on the floors.
