Once the investments are cool enough to be handled (around 300 - 400°C), they are placed in a bed of sand to support them.
Meanwhile, the bronze is being melted in a furnace.
Once the metal reaches 1200°C, it is ready to be poured into the ceramic shell investment. This is done by decanting the metal into a pre heated small pot - a crucible - and then poured into the investment at a reasonable speed.
The investments, now filled with bronze, are left to cool until the following day.
