Evaporating dishes. 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.
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 ...
Glass evaporating dishes, such as watch glasses, are primarily used as an evaporating surface (though they may be used to cover a beaker.) The Petri dish is a flat dish filled with a nutritious gelatin that allows for microorganisms to quickly grow, its named after its inventor Julius Petri in the 1880s.
Unlike wire gauze, which primarily supports glassware such as beakers, flasks, or evaporating dishes and provides indirect heat transfer to the glassware, the pipeclay triangle normally supports a crucible and allows the flame to heat the crucible directly. The triangular shape allows rounded crucibles of various sizes to rest in a stable way.
Evaporating dishes made of chemical porcelain. A type of porcelain characterised by low thermal expansion, high mechanical strength and high chemical resistance. Used for laboratory ware, such as reaction vessels, combustion boats, evaporating dishes and Büchner funnels. Raw materials for the body include kaolin, quartz, feldspar, calcined ...
Crucible tongs are scissors -like tools with a pair of attached arms that curve outward near the ends to form a rounded gripping area that allows users to safely grasp crucibles, flasks, evaporating dishes, or small beakers. [1] They are made of durable metals —stainless steel, brass, or nickel, for example—that can withstand high temperatures.
Corning manufactures Vycor products for high-temperature applications, such as evaporating dishes. [citation needed] Porous vycor is a prototypical matrix material for the study of confined liquid physics. [citation needed] Vycor can also be used for removal of 231 Pa and 233 Pa in fuel recycling.

Evaporation. Aerosol of microscopic water droplets suspended in the air above a cup of hot tea after the water vapor has sufficiently cooled and condensed. Water vapor is an invisible gas, but the clouds of condensed droplets refract and scatter the sunlight and are thus visible. Droplets of water vapor in a pan.
