How can you tell if something is soapstone?

To identify soapstone, look for its characteristic softness, which allows it to be scratched with a fingernail. It typically has a smooth, soapy feel and a waxy luster. The color can range from light gray to dark green or blue, often with veining. Additionally, soapstone is heat-resistant and non-porous, making it a popular choice for countertops and sculptures.
