What is the use of wire gauze in laboratory?

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.
