At Iron Museum, Coalbrookdale, Shropshire - and the start of the Industrial Revolution.

Imagine a pot:


(black, round, singing when struck)
and the very idea


of making many
as reliably round as a canon shot.


Think, then, of this
coke instead of smouldered wood


an iron ore charge
and bellows powered by a wheel


and iron, pouring forth
like blood


deoxygenated, venal.
