"The section and ground plan of one of the older forms of open-mouthed furnaces used at Dowlais (Truran), consisting of a heavy mass of mascury, square at base, strongly braced together with iron tie-rods, rising in the shape of a truncated pyramid to the height of the boshes, and then surmounted with a conical top surrounded at the throat by a gallery for the introduction of the enarging materials. In the square base were four arched recesses or tuyere houses, one on each side, F, F, for the introduction of G also serving for the removal of cinder and the tapping of the furnace for the running of the pig. The lowest portion of the hearth or crucible, A, was constructed of refractory sandstone, grit, or conglomerate, or of difficulty fusible firebrick, the inner portion of the upper part of the furnace being also built of firebrick set in fireclay with an air course between the double lining thus constructed; exteriorly the furnace was built of less expensive and refractory materials, usually of stone, strongly bound round with iron hoops." — The Encyclopedia Britannica, 1893

"A verticle section of one form of blast-furnace is represented [here]. the crucible (C) is the part of the furnace in which the molten matte and slag collect. The body of the furnace consists of two concentric shells (cs), made either of wrought iron or of steel, between which cold water (W) is caused to circulate to precent the inner shell becoming heated...Pipes called tuyeres (T) enter the furnace a short distance above the hearth...Above the body of the furnace extend the hood (H) and the stack (S). A door (D), used in charging the furnace, is placed in the hood." -Brownlee 1907

A furnace apparatus for minting. The metal is first melted in the crucible in flue A. The pulley W is used to pull out the crucible from the flue. The melted metal is transferred to the moulding apparatus, where it gets poured into mouldings by hand.
