The contour and dimensions of a typical blast furnace are shown in fig. 1. The shell of the furnace consists of riveted steel plates, inside which is a lining of firebricks varying in thickness about 2–3½ feet. Molten iron collects in the crucible or hearth at the bottom of the furnace and is periodically run off through a hole in the side of the furnace known as the tap-hole. The hearth is lined with firebrick both around the sides and along the floor, the total thickness of brickwork below the hearth in fig. 1 being 3 feet 9 inches.

page 88 note 1 Alfred Hartley Jay (1906–47) had been working on this same problem and this appendix contains his notes dated February 19, 1947. He died on February 26, 1947, after a motor-car accident on February 22. Two papers by him in this Magazine (1944, vol. 27, pp. 54 and 56) gave much promise of further useful work.
