The mansion previously has been owned by a general manager of General Motors’ Saginaw Malleable Iron Division plant and a councilwoman.

By this additional heating, hammering and rolling, all the different qualities of the scrap iron composing the pile are merged into one homogeneous material, having the fibre given to it that was lost in the separated portions of the scrap iron; and this, when cut up into proper lengths, and again piled and shingled into the slab, results in a material possessing somewhat the closeness and density of steel, while retaining all the toughness and tenacity of superior malleable iron.

By this process a portion of the carbon in the casting is removed, and the strength and toughness of the latter become more like the strength and toughness of wrought or malleable iron.

Wrought or Malleable Iron.—This is nearly pure iron, and is made from cast iron by the puddling process, which consists chiefly of raising the cast iron to a high temperature in a reverberatory furnace in the presence of air, which unites with the carbon and passes off as gas.

Table-knife blades are forged from shear and other steels, and, if they are not in one piece, a bit of malleable iron sufficient for the bolster or shoulder and tang is welded to each, often by machinery, especially in the case of the cheaper qualities.
