Even though its named after Robert W Bunsen, it was actually just an improvement of the design that his laboratory assistant, Peter Desaga in 1855, made on a previous design produced by Michael Faraday.WARNING!Unless working directly with the Bunsen burner have the safety flame on so others or your self dont get burnt! Only once your ready for your experiment you open the air holes.

And rememberSafety flame = closed air hole = orange and red colour = cooler flame Hot flame = open air hole = clear and blue = hotter flame= hotter flame Packing awayTurn off gas
