  2. Evaporating dish - Wikipedia

    en.wikipedia.org/wiki/Evaporating_dish

    An evaporating dish is a piece of laboratory glassware used for the evaporation of solutions and supernatant liquids, [a] and sometimes to their melting point.Evaporating dishes are used to evaporate excess solvents – most commonly water – to produce a concentrated solution or a solid precipitate of the dissolved substance.

  3. Watch glass - Wikipedia

    en.wikipedia.org/wiki/Watch_glass

    A watch glass is a circular concave piece of glass used in chemistry as a surface to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance, and as a cover for a beaker. When used to cover beakers, the purpose is generally to prevent dust or other particles from entering the beaker; the watch glass does ...

  4. Vacuum flask - Wikipedia

    en.wikipedia.org/wiki/Vacuum_flask

    A vacuum flask (also known as a Dewar flask, Dewar bottle or thermos) is an insulating storage vessel that slows the speed at which its contents change in temperature. It greatly lengthens the time over which its contents remain hotter or cooler than the flask's surroundings by trying to be as adiabatic as possible.

  5. Liebig condenser - Wikipedia

    en.wikipedia.org/wiki/Liebig_condenser

    The Liebig condenser (/ ˈ l iː b ɪ ɡ /, LEE-big) [1] or straight condenser is a piece of laboratory equipment, specifically a condenser consisting of a straight glass tube surrounded by a water jacket. In typical laboratory operation, such as distillation, the condenser is clamped to a retort stand in vertical or oblique

  6. Bell jar - Wikipedia

    en.wikipedia.org/wiki/Bell_jar

    A bell jar is a glass jar, similar in shape to a bell (i.e. in its best-known form it is open at the bottom, while its top and sides together are a single piece), and can be manufactured from a variety of materials (ranging from glass to different types of metals).

  7. Evaporation - Wikipedia

    en.wikipedia.org/wiki/Evaporation

    Evaporation is an essential part of the water cycle. The sun (solar energy) drives evaporation of water from oceans, lakes, moisture in the soil, and other sources of water. In hydrology, evaporation and transpiration (which involves evaporation within plant stomata) are collectively termed evapotranspiration. Evaporation of water occurs when ...

    Both experts agree it’s best to store water in glass bottles with closed caps. Riese is a strong believer in glass bottles, “as glass does not give anything to water or of water, so it’s the ...

  9. Prince Rupert's drop - Wikipedia

    en.wikipedia.org/wiki/Prince_Rupert's_drop

    Prince Rupert's drops are produced by dropping molten glass drops into cold water. The glass rapidly cools and solidifies in the water from the outside inward. This thermal quenching may be described by means of a simplified model of a rapidly cooled sphere. [ 3 ]
