How to use a Bunsen Burner - Bunsen Burner Parts and Functions - Alpha Genomics

[@Gamdun]

Actually there is no concept of clockwise etc , in fact when the nob is parallel to the gas pipelines the flame will be the highest & when it makes some angle with it the flame will be lower and it will be put out when there's an angle of 90 degrees between the nob & the gas pipeline. The burner can be put out by rotating the nob in either way.
