Not illustrated. 1880 Excerpt: ... iron from the pig to the state of finished bars. The finery was of the exact form but smaller than those now used. The chafery or hollow fire was, in fact, the same as the present smith's forge fire, but on a larger scale, and the "hollow" or chamber, in which the bloom was heated, was made by coking the coal in the centre with the blast, and taking care not to disturb the mass of coal above, which was used to reverberate the heat produced. Both the finery and chafery were worked by blast. The hammers were of two descriptions: the forge hammer a heavy mass for shaping the blooms, and the tilt hammer, much lighter, and driven quicker for shaping the bars. The charge for the finery was about 1 cwt. of pig iron: this under the first process was reduced to 1 cwt. It was, when ready, put under the forge hammer, and shaped into a bloom about 2 feet long and 5 inches thick; this was then heated in the chafery, and, under the tilt hammer, drawn out to a bar 3 to 4 inches wide, and half an inch thick. The manufacture up to this point, until a recent period, was carried on by the ironmasters, and the iron in this state was sold under the name of "tin bars " to the platemakers. The average price for these bars, from 1780 to 1810, was 21 per ton. The sheet and cold rolls were then in use nearly as at the present time. In 1807 Mr. Watkin George, whose position had been established as one of the first engineers of his time, by the erection of the great water wheel and works, at Cyfarthfa, removed to Pontypool, and undertook the remodelling of the old works there. His genius was equal to the task. He clearly saw that the secret of the manufacture was to produce the largest possible quantity with least possible machinery and labour. H...
