Abstract
A method for manufacturing a plurality of glass microspheres comprises: melting a batch into a first glass melt in a melter system, processing the first glass melt into a second glass, pulverizing the second glass into a plurality of glass fragments, thermally processing the plurality of glass fragments into a plurality of glass microspheres, providing at least one of a plurality of redox reactions and a plurality of events in at least one of the first glass melt and a melt of the second glass, and the plurality of redox reactions and the plurality of events are induced by a plurality of redox active group (RAG) components.

A method of producing microspheres, comprising:
- melting a batch into a first glass melt;
- processing the first glass melt into a second glass comprising adding a gas to the first glass melt;
- pulverizing the second glass into a plurality of glass fragments comprising (i) sulfide and (ii) sulfate, and
- thermally processing the plurality of glass fragments into microspheres, wherein the thermally processing comprises heating to cause reaction of (i) the sulfide with (ii) the sulfate, to form SO2 gas,
- wherein the second glass has a melting temperature less than the first glass, and
- the gas comprises a sulfur containing compound.
A method of producing microspheres, comprising:
- melting a batch into a first glass melt;
