Research of the mineralogical characterization by the point of view to inert or stabilized conditions, is now on the first step, to offer more useful tool for waste management . In landfill site, it should be the useful the mineralogical characterization based on optics and an X-ray analysis, etc., to determine the crystal structure and mobility of harmful elements from waste Between the leaching test which are done to the respect of stability for the incineration ash or slag, there is the mineralogical changes in the ashes . Especially, it has been understood that the decrease of extraction, cased by ettringite, phase and making to the carbonic acid is confirmed . When the mineral aspect changes after the water contact, the appearance of a specific mineral is expected that it becomes the index of stability, and "Mineralassei" that expects the stability in the past and the future is possible. In the evaluation by the JLT19 method, it has been understood that it is the one that the framework element does leaching test, and the grasp of the interrelation with a mineralogical change is important. Moreover, the chance of quantification by the Insoluble parts evaluation was able to be gripped .
