he plant produced its irst zinc oxide from Friedensville ore in late 1853 and quickly went on to out-produce the Newark Zinc Works. In the zinc oxide works, the pulverized ore was mixed with anthracite coal and placed on a bed of burning coal on the grates of Wetherill furnaces. Forced air caused the temperature to rise and me-tallic zinc to be ...
