A millimetric piece of Balmuccia peridotite was melted and quenched in the laboratory. The SEM picture shows a biphasic glass: metal oxides in the dense (white) spheres and a lighter silicate phase. Around the spheres a myriad of (sub)micrometric crystals formed. The larger ones reach about 1 micron.
