• Solids that are trapped on the surface of the drum are washed and dried after 2 / 3 of revolution, removing all the free moisture [ 6 ].
• Additional sprues may be directed upward at intermediate positions, and various vents may also be added where gases could be trapped . ( Vents are not needed for ceramic shell casting, allowing the sprue to be simple and direct . ) The complete wax structure ( and core, if previously added ) is then invested in another kind of mould or shell, which is heated in a kiln until the wax runs out and all free moisture is removed.
