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.
as temperature rises the kinetic energy rises so as the masses youll weighed .
wear gloves -yes i was the first to answer this question - (cheese) =)
Make sure to use tongs if dish is hot, as to protect skin from burns
the safety precaution in using simple machines is to use it in a safety hand

it is a dish that evaporates with chemicals
The evaporating dish would not be harmed if it was heated on a hot plate, but it should be heated on a bunsen burner.
Which of the following is a general safety precaution when doing a collection:
Evaporating dish is usually made out of glass.It is shaped like a saucer.It is used mostly when dealing with inorganic aromatic compounds.
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.
Evaporating dishes are used to boil solutions. Crucibles are used to heat solids very strongly.
