So that the substance in the evaporation dish is fully protected with the glass! The evaporating dish is used to heat and evaporate liquids. This porcelain item resembles a shallow bowl with a spout. Evaporating dishes are traditionally used to evaporate solvent to concentrate a solution; however they can also be used to hold sand for a sand bath, as a small water bath, or as a drying dish (like a watch glass). If heated by a direct flame, it will often be placed on a clay triangle for support. Thank you for your time! peace.....

Salt remain as residue after evaporation.
It is a shallow bowl or dish so that a small amount of liquid has a large suface area. Evaporation of the solvent is relatively rapid and leaves behind the solute usually in a fine powder/crystalline form.
A Petri dish (or Petri plate or cell culture dish) is a shallow glass or plastic cylindricallidded dish that biologists use to culture cells[1]or small moss plants.[2
evaporating dish is used to let substances to evaporate.-aramis nats-Evaporating dishes are used to evaporate excess water - or other solvents - to ensure that a concentrated solution or the dissolved substance is left behind.an evaporating dish is put on top of a tripod over a Bunsen burner and liquids are evaporated off like water evaporated off salt water leaving salt.to let the solvent evaporate and collect the solute in solid state from dissolved stateIt is used to evaporate water from solution to obtain solid materials.
Evaporating dish is usually made out of glass.It is shaped like a saucer.It is used mostly when dealing with inorganic aromatic compounds.
Evaporating dishes are used to boil solutions. Crucibles are used to heat solids very strongly.
An evaporating dish is a shallow, wide dish that is meant to create a large surface area exposed to air. It is used to allow liquids to evaporate into the air quickly.
An evaporating dish comes in a number of sizes, and are usually made of ceramic or glass. All evaporating dishes are bowl-shaped, though some are a lot shallower than others. the evaporating dish is used for just what you would imagine: evaporating liquids over a heat source. I have also seen the larger (white ceramic) dishes used in titrations, where the endpoint is observed against the white of the dish.
An evaporating dish is a piece of laboratory glassware used for the evaporation of solids and supernatant fluids.Answer taken from wikipedia.

The name is clear: it is used to evaporate a liquid to obtain the solid residue.
it is a dish that evaporates with chemicals
