Metals change the colour of a flame when they are heated in it. Different metals give different colours to the flame, so flame tests can be used to identify the presence of a particular metal in a sample.This is how you would carry out a typical flame test: 1  dip a clean flame test loop in the sample solution. 2  hold the flame test loop at the edge of a bunsen burner flame.lame tests are useful for confirming the results of a precipitate test.
