A method of making a foam glass having a substantially uniform pore size by first providing a substantially homogenous mixture of a milled glass and an activated carbon foaming agent, and then heating said mixture in the presence of oxygen to a temperature sufficient to react said foaming agent with oxygen. Preferably, the mixture is heated to a temperature of between about 700° C. and about 850° C., and more preferably the mixture is heated to a temperature of between but not limited to about 750° C. and about 800° C. The milled glass is preferably provided as waste soda lime glass. Preferably, the carbon foaming agent is milled to a substantially uniform particle size of less than about 400 mesh, more preferably less than about 325 mesh, and more preferably less than about 270 mesh. Preferably, the glass precursor is milled to a substantially uniform particle size of less than about 400 mesh, more preferably less than about 325 mesh, and more preferably less than about 270 mesh.
