Wire gauze is a small square of metal material that kind of looks like a tiny fence. It's used in science experiments to keep things steady and strong when they're being heated up.
When you're cooking on the stove, you might notice that the flames are really hot and they can burn things easily. Wire gauze is kind of like a shield that protects things from getting burned by the flames.
So when scientists want to heat something up without burning it or causing a big fire, they put wire gauze under it. The wire gauze doesn't get as hot as the object being heated, so it can help spread out the heat evenly and keep everything safe.
Wire gauze is also used in some types of chemistry experiments to help support different objects, like test tubes or beakers, so they don't fall over while something is being heated up. Basically, wire gauze is a helpful tool that scientists use to keep things under control and prevent accidents!
