Note 178 — Chapter IV · (XI.)

Plate VIII, D, gives a section through the model in the casting-pit, when all is ready for the actual operation of introducing the molten metal. The wax has all been run out, and the outline of the figure and of the horse is marked by a double line with a narrow space between. It is this space that will be filled by the bronze which will be introduced through numerous channels so that it may be distributed rapidly and evenly over the whole surface it is to cover. When in the pit the mould is packed all round with broken bricks or similar material, so that ‘the bronze may not strain it,’ nor cause it to shift.
