What is a tripod for in chemical experiments?

There are two types of tripods: an iron tripod and a tripod stand.

A tripod is a tool for placing a crucible or spirit lamp during heating, a tool for supporting and preventing rupture when heating a crucible or spirit lamp. The iron tripod has three legs for stability. Place the asbestos net on the tripod and place the spirit lamp on the net to heat it up.
