Thanks, but the same article also states that the products with high carbon content was unforgeable. A bloom is not like the blast furnace where the very high carbon steel per your definition is puddled and poured into a mold. A bloomery puddles the slag and leaves the iron + carbon (varying degrees of carbon steel per your definition) in solid form which has to be forged into shape. To reduce the carbon enough into forgeable form, you still need a finery hearth that the Celts lacked.
