1, look at the color, beef bones are white and natural, and bone products are mostly bleached. Even if the bovine bone is bleached, it will show an oily white luster, while the bone products will dry after bleaching. Plastic products are dull, unnatural and dull.
2. Look at the texture. Real cattle have thin bones, fine ripples and no bone eyes. In contrast, bone products are rough in texture, with thick lines and bone eyes. Plastic products often have no lines.
3, look at the weight, from the weight point of view, the same size of decorations, due to the large proportion of cattle bones, tooth carving is obviously heavier than bone carving and plastic products.
4, look at the workmanship, most of the real cow bones are finely crafted, and the products are mostly round. However, bone products are rough because of their own materials, even if they are carefully made. In addition, because of the small material, bone products are mostly oval or oblate in shape, and the surface is uneven. Plastic products often leave traces of molds. The patina of bovine bone beads is natural and vigorous, and it is a very good collection. The wenwan category is more valuable and has a high collection value.
