# Long description

Figure 10 shows an illustration of a Bunsen burner in which its components are labelled and the position of nichrome wire for a flame test is shown. The Bunsen burner is a metal thin hollow vertical tube on a flat metal stand. Gas passes into this via a flexible rubber tube and is controlled by the barrel, which is at the base of the metal tube. This can be rotated to allow gas to pass up the main tube. In the diagram this is open, so gas is passing through and the flame at the top of the metal tube is blue. A thin long nichrome wire is shown being held in the side of the flame. This has a loop at the flame end and a cork at the other. The cork is used to hold the wire.
