A process and a product made by the process for producing black glass from incinerated municipal waste including separating metal, stone and ash from the waste; melting the glass material comprising ferrous oxide and ferric oxide to convert at least a portion of the iron oxides to Fe3O4, thereby causing the black coloration; and thereafter solidifying the molten glass.

A process for producing black glass comprising: (a) reclaiming glass material including ferrous oxide and ferric oxide from incinerated municipal waste, (b) melting said glass material in the range from about 1300°C. to about 1500°C. to convert at least a portion of the iron oxides therein to Fe3O4,

A process for producing black glass comprising: (a) reclaiming glass material including ferrous oxide and ferric oxide from incinerated municipal waste, (b) melting said glass material in the range from about 1300°C. to about 1500°C. to convert at least a portion of the iron oxides therein to Fe3O4, thereby causing black coloration of the glass material and stratifying the mixture wherein one of the layers comprises a substantially homogeneous black glass, (c) cooling the molten glass to obtain a middle layer of substantially homogeneous black glass and a top and bottom layer of non-homogenerous material, the top layer being of extraneous and undisolved matter and the bottom layer being of concentrated metals, (d) removing the non-homogeneous material from the substantially homogeneous black glass layer.
