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."
This depends on your specific application !
A flame is not extinguished when a wire gauze is placed on top of it because the flame is still exposed to oxygen. The gauze has holes, through which oxygen can flow. Additionally, oxygen can reach the flame from under the gauze. Consequently, the flame is not extinguished.
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).
it is used for supporting the stand
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

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.
The asbestos in the wire gauze i think is a soft type of asbestos coz` some of the asbestos is very thick
It is sort of like a fabric, just made of wire.

A wire gauze is a mesh made from wire, and is basically used as a filter or s sieve.
it helps in providing constant heat
because it is used in heating an chemical.
