Feature

●The urns are made of aluminum oxide and the firing temperature is 1800 degrees and the sintering time is 40 hours
●Can not be used in temperatures exceeding 1800 degrees
●Heating speed is not 50 degrees/10 minutes
●Do not dissolve materials that may react with Al2O3. Avoid the reaction of aluminum oxide
