These factors aid glass forming and cooling without crystallisation. The devitrification heat treatment must be carefully controlled to ensure the maximum number of nuclei are formed and that these nuclei grow into a uniform fine crystal structure.

WebAmorphous glasses, including fused silica, can be etched in a similar way to single-crystal quartz. Examples are the isotropic etching of borosilicate glass in hydrofluoric acid (HF), in which a strip-opening in the masking layer will result in a hemispherical channel structure if sufficient etch time is allowed.
