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.
This is unknown, but we do know that as far back as ancient Sumerian times (thousands and thousands of years ago) they were well aware of evaporation, and used it to get salt from the sea.
It is mentioned in babylonian texts and in The Bible.
- Jer 10:13 When he uttereth his voice, there is a multitude of waters in the heavens, and he causeth the vapours to ascend from the ends of the earth.
- Ps 135:7 He causeth the vapours to ascend from the ends of the earth.
There is no single professor or scientist that is accredited with the discovery, because it has been part of the general pool of human knowledge for tens of thousands of years.
Nils Wallerius - Swedish - between 1739 - 1747 made a special study of evaporation.

What does an evaporating dish looks like?
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.
What is the uses of evaporating dish?
Also known as watch glasses, evaporating dishes are used in chemistry in order to evaporate substances, most usually water, to produce a more concentrated solution or a solid precipitate of the dissolved substance.
What is Evaporating Dish used for?
They are used to evaporate liquids. Specifically, the goal is to separate the fluid from any dissolved solids therein. Lets say you want to get salt out of water- you can't drain them by hand, so you evaporate the water, which leaves the salt there.

What is an evaporated dish?
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.
What are evaporating dishes used for in chemistry?
An evaporating dish is a piece of laboratory glassware used for the evaporation of solids and supernatant fluids.Answer taken from wikipedia.
What is the difference between watch glass and evaporating dish?
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.....
What is an evaporating dish used for?
An evaporating dish is used to evaporate liquids from a solution, leaving behind the solid solute. This is often done to concentrate a solution or to isolate a solid compound. The dish is heated gently to speed up the evaporation process.
Why use an evaporating dish instead of a beaker for sublimation?
An evaporating dish is better for sublimation because it has a wider surface area which allows for faster evaporation of the solid substance. This helps in obtaining the purified sublimate more efficiently. Additionally, the flat bottom of the evaporating dish ensures even heating, which is important for the sublimation process.
What is an evaporating dish and how is it labeled?
An evaporating dish is a small, shallow vessel used to heat and evaporate liquids slowly. It is typically made of ceramic or glass. It can be labeled with a heat-resistant marking or have a designated area where labels can be attached.
What is the meaning of evaporating dish lab apparatus?
An evaporating dish is a laboratory glassware used to heat and evaporate liquids slowly to leave behind solid residues. It is commonly used for concentrating solutions, crystallizing compounds, or drying samples.
