         This research demonstrates the design and construction of a small electric furnace for glass melting experiments in a laboratory. This furnace is an open front door furnace designed for a 200 ml crucible. The maximum temperature of the furnace is 1200 °C. The furnace consists of heating coils placed on both side walls with a total resistance of 12 ohms. Temperature is controlled with a PID temperature controller. Temperature is measured using a Type K thermocouple installed in the center of the back wall of the furnace. Test results show that the furnace can melt glass at a maximum temperature of 1200 °C. This furnace has many advantages: Its small size allows the temperature of the furnace to be precisely controlled. Save space Save energy, reduce electricity bills, easy to maintain. Including saving on maintenance costs.
