Is the fireplace in your house marble?

Have you checked the material of your house's fireplace? Is it marble or other material? The snow plaster is a kind of translucent, fine stone, which is often mistaken for marble. It is soft and easily engraved and polished. It is now used in a lot of indoor ornaments. Like marble, it is a metamorphic rock, but the difference is a component part: it is mainly composed of hydrated calcium sulfate. "Hydration" refers to the inclusion of water in its crystal structure, which affects its durability and deterioration.

The snowflake gypsum can be dissolved in water and can be damaged by heat. Heat expelled water from the crystal structure and could not be reintroduced. This effect is a translucent and irreversible loss, while snowflakes show a dim and opaque appearance. The only way to avoid this is to avoid exposure to high temperature. Agate "marble" is sometimes called alabaster, because they have similar appearance, but they are actually more durable polished limestone than gypsum gypsum.
