Vermiculite typically appears gold, brown, or silver in color. The exact shade can vary depending on the specific type and its origin.
- Gold vermiculite is the most common type, often found in gardening products and insulation.
- Brown vermiculite is another common variety, often used in construction and fireproofing.
- Silver vermiculite is less common and is often used in high-performance insulation applications.
Vermiculite's color can also be affected by its processing and treatment. For example, vermiculite that has been heated to a high temperature may appear darker or more reddish.
