Features:

During the solidification phase of the metal, a contraction occurs. To
compensate for this and the resulting negative pressure, liquid metal is sucked
out of thicker layers. With this knowledge came the idea of ?? the "lost
head". This is located on the casting pin in the center of the muffle and
serves as a shrinkage reservoir.
