The mid-infrared spectral evolution of amorphous metastable eutectic magnesiosilica smokes, obtained by kinetically controlled gas-to-solid condensation of a Mg-SiO-O 2 -H 2 vapor, proceeded in three distinct phases as a function of increasing time and temperature. This paper reports the mineralogic
