How is the white stone defined?

Bailingbi stone is produced in several hills around Dudui Village, Chaoyang Town, Lingbi County. Due to the limitation of origin, it is easy to be confused with Baima calculus. I want to talk about some superficial views on the difference between white jade stone and horse tooth stone, and learn from each other with stone friends.

Bai Yushi, with color background as the top grade, followed by gray background and cement background. No matter what its background color is, we must first look at its whiteness. When it comes to whiteness, it is necessary to talk about the difference between it and horse tooth stone. The white stone is as white as snow, and it feels smooth without unevenness, among which the red (or blood tendon) line is the best. However, the whiteness of horse dental stone is pale white, with uneven feel and natural small cracks, which can only be distinguished by careful look. This is one of them. Second: Look at the fire knot between the white stone and the horse tooth stone. Bailingshi's acne is single, with irregular arrangement and many round beads. Special exceptions, and the fire papules of horse teeth stones are mostly connected in strips, and sometimes it is common to have "thorns". Third, the original stone of Bailing Stone can be seen clearly without hydrochloric acid treatment. Its stone surface is delicate, with natural grooves, and the distribution of fire bumps is relatively uniform, which makes people feel pity at first glance. However, most of the original stones of the horse teeth stone have rough surfaces, large and small bumps, and most of them are strip-shaped. Without hydrochloric acid treatment, there is a sense of unevenness. However, there are some unique shapes and some valuable collections of horse teeth stones. Finally, talk about the difference between the processed stone of Bailing Stone and Ma Ya Stone. The processing of liquor stone is mainly based on the appearance of liquor, and the background stone is kept as little as possible, especially the gray background or cement background. The requirements for the processing stone of the horse's tooth stone are stricter, and the horse's tooth stone leaves more background stones and less spirit.
