The Durability of Granite Sinks

Color Durability

• Granite's color stays consistent over the years. Granite is made when platonic rocks such as feldspar, quartz and smaller amounts of other minerals cool and harden. The other minerals in the granite will make veins of color in the granite. Heat does not affect the granite color. This color will not change over time unless a staining material sits on the surface of unsealed granite. Staining materials include wine, beet juice or lemon juice. You can remove these stains with a poultice, which will absorb the staining material and pull it out of the granite.

Texture Durability

• Natural granite has a rough texture, but builders can grind it down to a smooth and polished surface that will glisten. This texture will remain on the granite unless you scratch it with a harder substance such as metal or very sharp plastic. Heat does not affect the texture of the granite.

Stain Durability

• Granite is less porous than other types of building materials such as concrete, marble or wood. More porous materials tend to absorb stains easier than less porous materials like granite. Other types of stones will absorb a stain if you leave the stain to sit on it for too long.

Rust Durability

• Sinks, in general, are particularly susceptible to rust stains. This is because metal pans often sit in a sink and are full of water. They can rust, and the rusty water can run off onto the sink and cause it to absorb a rust stain. Because granite is not porous, it will not absorb rust stains easily and they will simply sit on the surface.
