Wire gauze can be used to support a container (such as a beaker or flask) during heating. When the bunsen burner flame is beneath it, with a tripod, the wire gauze helps to spread the flame (and heat) out evenly over the container.
It is frequently used in combination with an iron ring and ring stand with a bunsen burner underneath it (see the Related Questions for more information about an iron ring, ring stand, and bunsen burner & tripod).
A clay triangle serves a similar purpose, except that a clay triangle is used for a crucible instead.

When wire gauze is used in chemistry, it creates a precise, even heat dispersal. The wire gauze is centered on a ring stand, which allows an open flame to be in contact with it to a certain extent, depending on the desired heat. When an object is placed over wire gauze, it receives a more uniform heat, which is essential for the successful maintenance of the chemical process.
Because wire gauze is able to achieve this, it can also be used as a cooling surface for beakers, Erlenmeyers flasks or other vessels without damaging the supporting surface.
The use of a wire gauze in an experiment is to place under the container holding the liquid,that is being heated by the Bunsen burner, so that the container doesn't have direct conact with the flame.
In a laboratory, wire gauze is used to hold stuff on a ring stand; for instance, if you want to boil some water in a beaker using a Bunsen burner, you put a wire gauze on a ring stand, then put the flame under it.
It can also be used as a heat proof mat, in case you need to cool some substances in an apparatus, such as an evaporating dish after intense heating.
when using glassware, put a wire gauze on top of the tripod. the wire gauze spreads the heat so glassware does not crake :)
Wire gauze is a placed on the upper part of a tripod to help the uniform heating.
it prevents the heat of the apparatus directly. the circle thing on the wire gauze ensures that the heat is spread everywhere
it helps in providing constant heat

Wire gauzes with absorbent center are used in laboratory for heating, for example a beaker with liquid.
iron stand, iron ring, wire gauze, tripod
because it is used in heating an chemical.
This depends on your specific application !
Since the wire gauze is a good conductor of heat, all the heat is sttracted to the wire gauze
it prevents the heat of the apparatus directly. the circle thing on the wire gauze ensures that the heat is spread everywhere
the function is o clean the laboratory equipment
When the wire gauze is at room temperature, you can handle it with your hands. Once the wire gauze has been heated (say, by supporting a crucible over a Bunsen burner on a ring stand), you would need to use a set of tongs to handle the wire gauze (and the crucible and the ring of the ring stand if it needed to be dismantled immediately).

Actually wire gauze will burn when heated. I think you may instead be asking "Why will a flame not propagate beyond a wire mesh." But the answer to your question is: "A wire gauze WILL burn under appropriate heat."
the base of an evaporating dish is rounded and will not be stable when placed on a gauze, hence a triangle (tripod) to hold its base better . Also, when you heat the beaker, you put the wire gauze above the triangle(tripod) and the triangle(tripod) above the Bunsen burner.
Generally it is used with a ring stand and a ring. The wire gauze is placed on the rind, a beaker or flask is placed on the gauze, and heat is applied by a Bunsen burner.
