Description
English: A Blomary Fire. The cavity of the hearth d … was lined with fire-resisting stone. … The tuyère, b, was placed from seven to eight inches above the bottom of the hearth, and was contrived so that its inclination could be varied at pleasure. The blast was produced either by the "trompe" or by wooden or leather bellows. … The bottom and sides of the "hearth" having been lined with a thick coating of charcoal dust, it was then filled with charcoal, upon which crushed ore was thrown, and kept in place by a dam of charcoal dust (c). … [O]re and charcoal were added from time to time as the work progressed, and sometimes the mass of fuel and ore was heaped up three or four feet.
