Inert atmospheres consisting of gases such as argon, nitrogen, or helium are commonly used in chemical reaction chambers and in storage containers for oxygen-or water-sensitive substances, to prevent unwanted reactions of these substances with oxygen or water. [4] Argon is widely used in fluorescence tubes and low energy light bulbs.
Uses of fibreglass include building and construction materials, boat hulls, car body parts, and aerospace composite materials. [92] [89] [91] Glass-fibre wool is an excellent thermal and sound insulation material, commonly used in buildings (e.g. attic and cavity wall insulation), and plumbing (e.g. pipe insulation), and soundproofing.

The walls of glass ampoules are usually sufficiently strong to be brought into a glovebox without any difficulty. Glass ampoules are more expensive than bottles and other simple containers, but there are many situations where their superior imperviousness to gases and liquids and all-glass interior surface are worth the extra cost.
Tap water is not sterile and may contain waterborne germs, such as bacteria, fungi and amebas, which form a biofilm barrier to water treatment chemicals — mainly chlorine and chloramine ...
Because of that, amorphous materials have a characteristic threshold temperature termed glass transition temperature (T g): below T g amorphous materials are glassy whereas above T g they are molten. The most common applications are in the making of pottery , glass, and some types of food, but there are many others, such as the vitrification of ...
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
“Drinking plain water is the best way to hydrate the body but there are options for those who do not like the taste of water, such as sparkling water,” adds Sue-Ellen Anderson-Haynes, M.S., R ...
Unless stated otherwise, the properties of fused silica (quartz glass) and germania glass are derived from the SciGlass glass database by forming the arithmetic mean of all the experimental values from different authors (in general more than 10 independent sources for quartz glass and T g of germanium oxide glass). The list is not exhaustive.
