How to Sculpt Limestone in Your Own Home

An easy way to make limestone sculptures without the need of fancy tools.

Get some CaCO 3 (limestone).

Cook the CaCO 3 (limestone) at high temperatures until it turns into a crumbly powder.

Take the CaO (the crumbly powder) and thoroughly mix with a small amount of water until paste.

Sculpt the CaH 2 O 2 (the paste) into the desired shape of your limestone and dry.

Tips

• Don't be alarmed if your limestone doesn't look right; normal limestone is formed under intense heat and pressure, yours wasn't.
• CaCO3 (limestone) ---> CaO (powder) + H2O (water) ---> CaH2O2 (paste) ---> CaCO3 (limestone)

Warnings

• Don't use oil.
• Danger! The CaH2O2 (paste) is a strong base. Very corrosive!
• This powdery and paste substances can burn skin slowly. The more moisture involved, the greater the burn.

Things You'll Need

• limestone
• rubber gloves (for handling the CaH2O2 (paste)
• goggles
