The melt is prepared in an external heating furnace designed to generate the simulant melt. The cylindrical furnace is 0.58 m in diameter and 1 m in height, and has a volume of 270 liter. The maximum temperature that can be reached to 900° C. Solid nitrate particles are charged in at the top of the furnace, and are gradually melt and heated up to a designed melt pour temperature, which can be kept till a test begins. The impurities inside the solid nitrate salt are burnout during the heating process. The heating furnace is hold by a framework which can be driven in axial direction and be tilted. The pouring operation is started by tilting the heating furnace. Melt is discharged into the test vessel via a heated pouring spout. In addition, the heating furnace is equipped with a vacuum pump, so it is possible to extract the residual liquid melt out of the test vessel back into the heating furnace. The already purified melt can be reused for the next experiment. In addition, the crust inside the test vessel is uncovered after extraction of liquid melt, and is therefore available for the post-test measurement and analysis.
