WebFor centuries the Europeans lacked methods for heating iron to the melting point at all. To produce iron, they slowly burned iron ore with wood in a clay-lined oven. The iron separated from the surrounding rock but never … WebThe tin melts slowly and runs down the slope, to be collected in a vessel, leaving the unmelted residues on the hearth. These are subsequently removed and treated. Vacuum distillation is sometimes used in fire refining. In this process, molten tin is heated in a dense graphite vessel at high temperatures (1,100 to 1,300 °C, or 2,000 to 2,375 °F).
