On Friday last one of the finest, thickest and heaviest armour-plates ever rolled in the world was pressed into the very perfection of a manufacturers armour-plate at the great Atlas Ironworks of Sir John Brown & Co, Sheffield. The size of this monstrous slab of iron when in the furnace was a little over 29 foot [8.84m] long by about 4 ft [1.22m] broad and 21 inches [0.53m] thick. Its rough weight was over 21 tons [21.3 tonne]. It was built up in the furnace before being rolled by five mould plates, each 3 inches [7.5cm] thick, and one solid plate of six inches [15cm]. This mass when reduced by intense heat to the consistency of dough was withdrawn from the furnace and in the course of less than a quarter of an hour was passed between the rollers many times, was reduced to a compact slab of iron of uniform thickness of 15 inches [38cm].4
