Heat it.
Calcium Oxide reacts with CO2 in the air to convert back into limestone. It also reacts violently with water. It will also blind you quickly. Probably one of these.
When you heat limestone it becomes calcium oxide but if you mean calcium carbonate then it should go down slightly due to the release of CO2
Calcium oxide.
carbon dioxide calcium oxide (quicklime) CaCO3 > CaO + CO2
The Chemical formula for lime is CaO. This comes from Limestone (CaCO3). As Limestone is heated up to 1000 degrees, it lets of Carbon Dioxide and becomes CaO, or quicklime.

calcium oxide calcium carbonate and something else....
Calcium oxide.
heat. limestone (CaCO3) ---> carbon dioxide (CO2) + calcium oxide (CaO)
When limestone (CaCO3) is heated, calcium oxide is produced!
Limestone is mainly calcium carbonate, CaCO3. When heated, it breaks down to form calcium oxide and carbon dioxide. Calcium oxide reacts with water to produce calcium hydroxide. Limestone and its products have many uses: for example, in mortar, cement, concrete and glass.
When heated, limestone forms two different things. It forms both calcium oxide and carbon dioxide. This occurs because limestone is made up of calcium carbonate.
carbon dioxide calcium oxide (quicklime) CaCO3 > CaO + CO2
Once burnt limestone turns into calcium oxide which is known as quicklime.
