‘Casting in wax – Pouring out the water’. After the wax was poured out, the mould and wax was filled with water to help it cool faster. After about an hour, Mauro poured out the water. You can see here how the 2 metal rods poking out centrally from the mould enable it to be lifted and poured easily using the gantry crane. You can also see the u-shaped metal rods that hold the plaster jacket of the mould together.
