Quizplus · Accepted Answer

Investment casting, also known as lost-wax casting, is a casting method that involves creating a wax model of the desired part, then encasing it in a ceramic shell. The shell is then heated and the wax is melted out, leaving a cavity that molten metal is poured into. Once the metal has cooled and solidified, the ceramic shell is broken away to reveal the final part.
