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

Wire gauze with an absorbent center is commonly used in laboratory settings to provide a stable platform for heating glassware or containers over a Bunsen burner. The absorbent center helps to evenly distribute the heat and prevent direct contact between the glassware and the wire gauze, reducing the risk of thermal stress and breakage.
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.See the Web Links and Related Questions below for more information.
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.
There are two types of wire gauze used in chemistry: a normally woven wire gauze, and one with a white circle imprinted on it. The latter has a ceramic composite intended to aid in the dispersal in heat. The normal set-up is a ring stand which a support ring attached to it. The wire gauze is centered on the ring stand as to allow the open flame to be in contact with it to a certain extent, depending on the desired heat. In the context of laboratory experimentation, the combination of the wire gauze plus the added ceramic composite greatly aids in the even dispersal of heat. This means that an object placed over this type of wire gauze will receive a more uniform heat from a Bunsen burner than the naked flame of it. This property is specially important in various chemical processes where precise, even heat dispersal is sought after, as a consistent heat is crucial for the successful maintenance of the chemical process intended. Because of this desired heat dispersal ability, wire gauze can also be used as a cooling surface for beakers, Erlenmeyers flasks or other vessels without damaging the supporting surface (workbench, tabletop, etc.).
The item above the tripod in chemistry is typically a wire gauze used to support a glassware, such as a beaker or flask, that is being heated. The wire gauze helps to distribute the heat evenly and prevent direct contact between the glassware and the heat source.
Most likely the reason you use wire guaze js when you are heating a beaker whitch is what most scientist or science teachers may use.The use of wire gauze can be found in appliances, Plumbing products and air filters, just to name a few. It is used to support a container during heating. The wire gauze helps to spread the flame out evenly. It is also used to filter liquids and solids. Some metals used include aluminum, copper, iron and platinum.Wire gauze has another interesting property: it serves as a flame arrestor. If the gauze is fine enough, flames don't travel through it. This is used as a safety feature in many objects. A wire gauze on top of a gas burner ensures that the flame stays out of the burner itself.The only use i can think of is when you put it on a tripod over a Bunsen burner to hold up a beaker in a science experiment.
