(1) the sample in the porcelain boat should be flat and the thickness of the sample shall not be too large;
(2) when the ash could open the door, the heat board containing sample boat slowly advance the high temperature furnace box furnace, the samples in the boat slowly ashing smoke, no longer smoke to sample a few minutes later, the boat slowly into the hot part in high temperature furnace, close the door to the sample 815 + 15 burning.
