STAGE 4

The wax replica, or second positive is fixed now for the bronze pour with wax rods or sprues through which the molten metal will run into the mold cavities.

In addition air vents to release trapped air when the metal is poured are also attached to the wax copy.

Next a ceramic covering is applied in successive layers to each wax positive by dipping it into a special mixture.

This ceramic covering is the second negative.
