Joseph Hall (metallurgist)

Joseph Hall 1789 - 1862, the inventor of 'Wet Puddling', was born in 1789 and apprenticed in 1806 as a puddler to use puddling furnace and later puddler's bosh cinder (iron scale, that is rust) to the charge. This caused the charge (to his surprise) to boil violently. When this subsided he gathered the iron into a puddle ball in the usual way, and this proved to be good iron.
