What is a pipestem triangle use for?

A pipestem triangle is a laboratory tool used primarily in chemistry to support apparatus during experiments, particularly when heating substances. It consists of a triangular metal frame with a ceramic center that can hold a crucible or other containers over a heat source, such as a Bunsen burner. The design allows for even heat distribution while maintaining stability. Additionally, it helps prevent direct contact of the container with the flame, reducing the risk of breakage.
