A wire gauze is placed on a tripod stand on top of a Bunsen burner.
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.
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.
it prevents the heat of the apparatus directly. the circle thing on the wire gauze ensures that the heat is spread everywhere
The primary purpose of a wire gauze mat is to support a container (such as a beaker or an Erlenmeyer flask) while it is being heated. The gauze mat also helps with an even distribution of heat as the Bunsen burner flame passes through the gauze to the container.
This serves to spread out the point of application of the heat.
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).
You can place a wire gauze on top of it and keep a safe distance away form the bunsen burner. Try not to perform anyexperiments while sitting down- it is safer while standing.
When heating beakers, a ring or square of wire gauze is placed on top of the tripod over the burner. The gauze may incorporate an asbestos pad or coating. The wire spreads the heat to prevent overheating of one part of the beaker.
