Furnace Fa is also cylindrical. This type of furnace appears to have been subjected to most intense firing as may be inferred from the fact that its mud walls have actually run down in pencil-like formations of slag. At a lower level is also seen, faintly at the right hand side, the section of a slanting flue which forms an obtuse angle with the body of the furnace. Twenty feet south of this furnace has been recovered a fragmentary earthenware crucible whose contents show that it was used for melting bronze. From inside, the walls are plastered with mud in which straw is added as an adhesive. A window is left at a convenient point whereby the fuel, the metal to be melted together with the crucible are put inside, and the window cover kept at hand.
