Reaction with acid to produce a gas, which is passed through limewater and goes milky if the gas is CO2. This would show the presence of carbonate in the sample.
Other tests include strongly heating the sample. Limestone decomposes to quick lime (CaO) and carbon dioxide. If you continue heating the lumps you will see glow, a white glow of limelight, an incandescent reaction which used to be used to light theatre stages. Limelight looks best if you use a hydrogen oxygen flame, but you still get a reasonable glow with normal gas flame. When cooled the lumps will react exothermically with water to produce slaked lime, Ca(OH)2
