Red sandalwood, or hongmu in Chinese, is a type of precious hardwood that is highly valued for its beauty and durability. Due to its premium status, however, there are often unscrupulous merchants who try to pass off inferior or counterfeit materials as genuine red sandalwood. According to national standards, only eight specific types of wood can officially be classified as hongmu. These include rosewood, padauk, fragrant wood, black rosewood, hongmu, wenge, ebony, and striped ebony, encompassing a total of 33 different species of wood. True red sandalwood has a distinct acidic scent, loose pores, and a rich reddish-brown to dark brown or even purplish-black hue. It typically has low oil content and an air-dry density ranging from 0.9 to 1.2 grams per cubic centimeter. In simple terms, the top and bottom surfaces of a piece of red sandalwood should exhibit a fairly consistent color difference, with the grain patterns running similarly on both sides. The natural color of the wood shouldn't be easily altered by wiping it with just a bit of water. Of course, if the wood has been artificially stained, this would be a different story entirely.
