When enough layers of the ceramic slurry* have eventually been added, the main body and the many smaller parts; arms, fins, cylinder, umbilicals, etc. are loaded into the furnace. The wax, now fully encased in the shell, melts and drains out of the bottom to be collected and eventually recycled. Any wax residue remaining burns off leaving a perfectly formed negative void. It is into this void that the molten bronze will be poured in the next phase; known as casting.
*Slurry is a binding liquid that is mixed with zircon sand. The wax components are dipped in the slurry and sprinkled with 3 different types of sand, ranging from very fine to rough. The fine and medium sand is for the detail, the rough sand is for the strength.
