Waste substance such as incineration ash is mixed with cullet and alkaline earth salt to form a mixed batch which is added to a glass melt heated solely by electrodes, producing an exhaust gas which is introduced into the batch thereby cooling the gas to produce condensation products. The alkaline earth salt reacts with alkali in the gas and the condensation products to produce a gall layer of alkali salts and alkaline earth salts which serve as a melt accelerator and are readily removed when accumulated. According to a further step the gas is purified by separating dust therefrom and introducing it into the batch as a slurry.

Process for converting solid, dehydrated waste substance into glass, comprising mixing the waste substances with at least one additive to form a mixed batch, generating a gall layer of alkali salt or alkaline earth salt on the surface of a glass melt heated solely by electrodes, and introducing the mixed batch onto said glass melt surface so that a major portion is melted into the melt and a minor portion produces an exhaust gas emerging from the melt, said gall layer serving as a melt accelerator, introducing the exhaust gas into the batch to be melted, thereby cooling said gas and producing condensation products in the batch, and reintroducing said condensation products into the melt with the batch.
