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.
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.
Most waterskins could hold between 18 and 27.5 L (5 and 7 US gallons; 4 and 6 imperial gallons) of water. [1] The disadvantage of waterskins is that people who have fetched water in the skin bottle and who have drunk water from the same have complained of the water taking on the bad taste of the goatskin.

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 ...
Glass bottles and glass jars are found in many households worldwide. The first glass bottles were produced in Mesopotamia around 1500 B.C., and in the Roman Empire in around 1 AD. [ 1 ] America's glass bottle and glass jar industry was born in the early 1600s, when settlers in Jamestown built the first glass-melting furnace.
The vacuum evaporation treatment process consists of reducing the interior pressure of the evaporation chamber below atmospheric pressure. This reduces the boiling point of the liquid to be evaporated, thereby reducing or eliminating the need for heat in both the boiling and condensation processes.
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 ...
Certain parts of a reusable water bottle, such as the straw and lid, have small crevices and spaces that are hard to reach with just a sponge. Consider using tools like a small, bristled cleaning ...
