During experiments, scientists have protocols they follow for safety. An iron ring provides support for flasks that may contain dangerous substances. If spilled, these substances can be hazardous to the health of those around them. It is very important to ensure that iron rings are used when necessary. In a lot of cases, iron rings are also used to hold crucibles in place because of the heat they conduct.
