Cilfái: Copper Smoke

I write about the copper smoke in Chapter Four of Cilfái: Historical Geography on Kilvey Hill, Swansea.

The copper smoke from White Rock was horrendous. Black, acrid, greasy and opaque. It killed everything it touched. The chemical composition of the Cornish copper ore meant that once burnt with Kilvey’s bituminous coal, released vast quantities of sulphur dioxide, hydreogen fluoride, sulphrous and sulphuric acids. in the 1840s, the Vivian’s Hafod Works were releasing 188 tons of Sulphuric Acid daily into the Swansea Valley.

Above: An extract from a rare coloured version of an image commonly used to show the forest of chimneys at White Rock in the 1860s The toe of the Cae Morfa Carw slag tip is left of centre and the mass of chimneys of Middle Bank is to the left. The drawing was commissioned by the French travel journal ‘Le Tour du Monde ‘ and the artist was Jean-Baptiste Henri Durand-Brager (Le Tour du Monde) 1865) (Author’s collection).
