What is the predominant color of Amosite?

• A. White; curly
• B. Blue; straight
• C. Brown/tan; long and straight
• D. Gray; short and curly

Answer: (C)

Amosite is a brown asbestos mineral, so its predominant color is brown (often described as brown or brownish-tan). Its fibers are typically long and straight, not curly. This combination—brown coloration with long, straight fibers—fits Amosite best. In contrast, white asbestos (chrysotile) is known for curly fibers, blue asbestos (crocidolite) is blue, and gray short curly fibers don’t match Amosite’s usual appearance.
