Textures – slag wall close-ups

Slag, close-up

When iron smelting was an important Black Country industry, huge amounts of slag were produced as a waste product.

Some was recycled, used for building walls. Many of these walls have been demolished in later redevelopments, but some can still be found. These close-ups are from the lumps on slag in just one wall, showing the textures created by cleavages, the sites of bubbles, etc.
