because it is used in heating an chemical.
This depends on your specific application !
Asbestos was commonly used in wire gauze as a fireproofing material in the past. Types of asbestos that may be found in wire gauze include chrysotile, amosite, and crocidolite. However, it is important to note that the use of asbestos in products like wire gauze has significantly decreased due to health concerns.
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 energy change when a wire gauze is heated with a Bunsen burner is primarily in the form of thermal energy. The burner heats up the wire gauze, causing an increase in its temperature. This increase in temperature represents a transfer of thermal energy from the burner to the wire gauze.
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 sort of like a fabric, just made of wire.
Wire gauze is used to provide a stable platform for the beaker during heating by diffusing heat evenly. This helps to prevent direct contact between the beaker and the heat source, reducing the risk of thermal stress and cracking. Additionally, the wire gauze helps to distribute the heat more evenly across the bottom of the beaker, ensuring uniform heating of the contents.
Wire gauzes with absorbent center are used in laboratory for heating, for example a beaker with liquid.
