The process begins by preparing the puddling furnace; this involves bringing the furnace to a low temperature and then fettling it. Fettling is the process of painting the grate and walls around it with iron oxides, typically hematite; [5] this acts as a protective coating keeping the melted metal from burning through the furnace. Sometimes finely pounded cinders was used instead of hematite.
