Joseph Hall (1789-1862), the inventor of 'Wet Puddling',
1789 Born at Tipton
1806 Apprenticed as a puddler to use Henry Cort's puddling process.
c1810 Married Elizabeth Danks
Over a period of years, starting in about 1811, Hall began to consider ways of improving the production of wrought iron. He eventually tried adding old iron to the charge of the puddling furnace and later puddler's bosh cinder (rich iron oxide and small pieces of iron) to the charge. To his surprise this caused the charge to boil violently (due to the oxygen from the iron oxide uniting with impurities in the iron charge). When this subsided he gathered the iron into a puddle ball in the usual way, and this proved to be good iron. This became known as 'pig boiling' or 'wet puddling' (as distinct from Henry Cort's 'dry puddling' process). The wrought iron was of high purity, and the process was less wasteful and required less time and labour than hitherto.
In 1830, with the financial support of others he established the Bloomfield Ironworks at Tipton,
Joseph Hall was good friends with George and Edward Thorneycroft, and with Mr Talbot, manager of Bagnalls Works; they discussed improvements in the methods of producing iron, such as "pig iron boiling"
1834 The firm became Bramah, Barrows, and Hall.
In 1838, Joseph Hall, Richard Bradley, and William Barrows patented the use of 'bulldog' (roasted puddling furnace cinder) to protect the iron bottom plate of the puddling furnace during the violent pig boiling furnace (Patent No. 7778, 21 Aug 1838).
In 1849, he moved to small house at Handsworth but continued to visit the works occasionally.
