Walk into the south-east shop at Darnall Works and look down. The floor is pitted with holes - 84 of them in this range alone, more in the adjoining workshops, 132 in total. Each one held a clay crucible. Each crucible held molten steel at temperatures hot enough to soften the soles of the puller-out's boots. This is the only place on earth where you can still see the full geography of crucible steelmaking laid out at scale, and for Sheffield - the city that practically invented industrial steel - that makes it sacred ground.

Naylor and Sanderson had been making cutlery and steel in Sheffield since 1776, working out of a tangle of premises near the city centre. When the Sandersons finally took the firm over and renamed it Sanderson Brothers, they wanted something purpose-built. In 1835 they took a 21-...

Crucible steelmaking, the process invented in Sheffield by Benjamin Huntsman in the 1740s, required brute patience. Iron bars were broken up, packed into clay crucibles with carefully measured carbon, and lowered into coke-fired holes in the floor. Each hole could melt about 30 k...

In 1873 and 1874 the Sandersons did something radical. They added a new range of crucible furnaces powered not by coke piled around the pots but by a Siemens regenerative gas furnace - a German innovation that recycled hot exhaust gases to preheat incoming air, dramatically reduc...

By the 20th century the open hearth and electric arc had made crucible steel obsolete for most purposes, though Sheffield's specialty steel firms held on stubbornly. In 1934 Sandersons transferred to Kayser Ellison, combining the sites into a larger Darnall Works. The old crucibl...
