Innovations has been conducting recently in order to obtain suitable crucible furnace for casting practice at vocational high school. This research is aimed at optimizing performance of compact crucible furnace by optimizing the crucible pot position. The crucible pot have diameter of 170 mm and height of 250 mm. The height of pot supporting are vary of 20, 40, 60, 80, and 100 mm. The furnace performance is determined by the rate of temperature rise to melt 3 kg of aluminium. Temperature changes measured by infrared thermometer. The result indicate that pot support of 60 mm gives optimum performance to compact crucible furnace. It is resulting temperature achievements of 600 C in 35 minutes. © Published under licence by IOP Publishing Ltd.
