Heating marble. A piece of marble (mineral of calcium carbonate, CaCO3) is heated in the flame from a propane Bunsen burner. When heated to 900-1200C, calcium carbonate decomposes into quicklime (calcium oxide, CaO) and carbon dioxide gas (CO2) CaCO3 -> CaO + CO2. Calcium gives the flame a bright orange-yellow color. The color of the flame is determined by the element's emission spectrum which is characteristic to that element. Therefore, flame test can be used as an analytic procedure for identifying elements.
