Hi, for the flame tests lab in chemistry, we used a prism-sheet to look through when the compounds were being put up to the flame a question on the lab asks how viewing the flame through a prism-sheet can make it easier to analyze the metal iron being tested personally all the prism-sheet did for me was make rainbows on the side lol. A flame test is an analytic procedure used in chemistry to detect the presence of certain elements, primarily metal ions, based on each element's characteristic emission spectrumthe color of flames in general also depends on temperature see flame color.
