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).
Wire gauge is a measurement of the diameter of a wire. It is commonly used to specify the thickness of electrical wires. The lower the gauge number, the thicker the wire. It helps in determining the wire's current-carrying capacity and electrical resistance.
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.
The middle of the wire gauze turns red hot first because that is where the flame is most concentrated due to its design. The wire gauze allows for more efficient heat transfer and concentration of the flame's heat energy in the center.
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."
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.

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.

A clamp or clamp holder is used to secure a beaker or flask to a ring stand. The clamp is adjustable to accommodate different sizes of glassware and can be tightened to hold the beaker or flask securely in place during experiments.

An iron stand is used to support items during heating or chemical reactions in a laboratory setting. It is often paired with a ring clamp and wire gauze to hold glassware or other equipment securely above the lab bench. This setup helps prevent direct contact between the heat source and the glassware, ensuring safe and controlled heating.
