Original Abstract Submitted
A phase separated composite glass has a first phase and a second phase. The first phase has an average microstructure size greater than a natural coursing limit of the phase separated composite glass (i.e., outside of what would be achievable by natural phase separation or otherwise in violation of the morphology constraints defined by a liquid-liquid immiscibility dome for the given bulk composition). Methods of preparing a phase separated composite glass based on a phase separated precursor glass or a template glass. Methods include combining a milled first glass corresponding to the first phase and a milled second glass corresponding to the second phase to form a glass mixture. Methods include melting the glass mixture at a temperature from about 25° C. to 0° C. less than an isotherm tie-line between endpoints of a pseudo-binary immiscibility dome defined by the phase separated precursor glass or the template glass.
