Abstract
A long time ago – when I was drawing cross-sections of
blast furnaces for metalwork A-Level – I noted the
existence of crushed limestone as part of the iron-making
process. I was never very clear what it was doing there –
something about acting as a flux to take the impurities into
‘slag’ that floated on top of the liquid iron, allowing it to
flow. But the main characters in the drama always seemed
to be the iron ore and the fuel (coke). Limestone always
seemed like an after-thought; a bit-part actor.
