description
During the devitrification process, the glass changes from being completely amorphous to partially crystalline, as it adsorbs moisture from the atmosphere. Devitrified glass has a frosty or cloudy, iridescent appearance. Devitrification occurs naturally over long periods of time, but can be induced by heating to high temperatures for prolonged periods of time. Compare this micrograph with micrograph ID 544, which shows the same sample rotated through 45°.
