Incineration ash was melted using a micro-scale furnace under various temperatures and gas atmospheres. As a result of the elemental composition analysis of the molten slag, it was confirmed that heavy metals with properties of low boiling points were readily emitted during melting treatment. The emission amount is influenced by vitrification behavior of the ash with operating temperature. The emission of lead and zinc under the reducing condition is larger than that under the oxidizing condition. Cadmium is completely vaporized under all conditions examined in the present study.
