This is a cotton wire net that lays between the fire when heating your beaker with an alcohol lamp. Scientific experiments use the name of cotton net, but now there is no problem with asbestos in white parts and it is turned into ceramic fibers.
As a scientific experiment tool, a round coating on the wire mesh is to prevent beaker and flask from getting hot directly into the fire. The size is 5.9 inches (15 cm) square, so it is useful as equipment for school science laboratories and research institutions.
The cotton wire mesh will not burn even on the fire of a gas stove or gas burner. It also helps prevent the evaporation dish from melting or cracking of an empty evaporation dish when it evaporates moisture and releases water solutions.
