Lost wax after casting

Ashanti gold weights from lost wax casting.

On the above is ashanti gold weight from casting, it includes carnelian, running rabbit and spirals. This is made from beeswax which when heated melts leaving the hollow which can be filled with brass. We made our models with wax, followed by investment process in which a wax pattern is used to shape a disposable ceramic mold. The last step was melting our metal and pouring it into a mold through a hollow channel called a sprue. The metal and mold are then cooled, and the metal part is extracted.
