An improved method of making glass products is provided which comprises mixing particulate used-container glass with a selected treating agent to form a unique glass mix. The used-container glass has a preselected approximate concentration range of foreign inclusions and an average reflectance of about 5% to about 95%. The mix is heated to a temperature and pressure above the sintering and softening point of the glass but below its melting point and within a range sufficient to activate the treating agent to either foam or fill the glass. In the latter case, increased pressure is applied to form the glass into a hard pressed product, such as a tile, appearance. In the former case, foamed glass of distinctive appearance is produced. The used-container glass includes a plurality of particles of various colors, and the pressed product may have oxide pigments embedded in the surfaces thereof. The treating agent can be dolomite or other suitable treating agent.
An improved heat treatable glass mix comprising:
An improved solid glass product comprising a unitary multi-colored mass of sintered, particulate used-container glass having a closed cellular foam structure and having the following approximate concentration of foreign inclusions:
An improved heat treatable glass mix comprising:
An improved solid pressed glass product comprising a unitary mass of sintered, particulate used-container glass having the following approximate concentration of foreign inclusions:
