It is 4 times harder than fused silica glass, 85 % as hard as sapphire, and nearly 15 % harder than bulletproof and blast-resistant windows and for many military infrared optics.

Moreover, the black, silica glass fiber tiles that cover the belly of the shuttle are famously fragile, so much so that even a bump or nudge can cause cracks or dings.

Free hydrogen atoms are able to bind to the SiO 2 silica glass compound forming hydroxyl ( OH )-a chemical compound that interferes with the passage of light through the glass.

It wasn't yet known whether the carbon panel or the silica glass-fiber thermal tiles on the wing had been burned through by the intense heat of re-entry or damaged in another way.

"' Soda-lime glass "', also called "'soda-lime-silica glass "', is the most prevalent type of glass, used for windowpanes and glass containers ( bottles and jars ) for beverages, food, and some commodity items.
38.
The "'Janus laser "'was a ( then considered high power ) two beam infrared neodymium doped silica glass laser built at Lawrence Livermore National Laboratory in 1974 for the study of inertial confinement fusion.

Chemical analysis of this glass has revealed that they are a soda-lime-silica glass but with a lower iron and manganese oxide content than the high iron, manganese and titanium glass used to make vessels.
