Metal molds wouldn't work in Tiki mug production. The molds need to be absorbent. Slip is used most commonly in Tiki mug making. Plaster molds are used because slip (basically clay that is watered down to be soupy) is poured into the mold and sloshed around a bit, and the excess is poured back out. The plaster absorbs the excess water, leaving a firm layer of clay in the mold.

So, using a metal mold with slip would leave you with a metal inside-out mug with a clay cocktail inside! Yum!
