Ahead of that, it experienced not been feasible to raise the temperature in the ore adequately to melt the iron website and the only out there iron was wrought iron developed by heating iron ore in the furnace with carbon given that the lowering agent and hammering the resulting spongy iron output. Furnaces of the working day could reach temperatures of about 1300°C which was ample to melt copper whose melting level is 1083°C although not plenty of to melt iron whose melting point is 1528°C.
