Will there be bubbles when Tian Huang is left for a long time?

I won't. Because natural Tian Huangshi has no bubble mouth, there are many imitations of Tian Huangshi made of artificial plastics on the market. Tian Huangshi is often imitated with translucent to nearly transparent light yellow plastic, while ordinary Shoushan stone is imitated with colored plastic.

Plastic imitations usually have bubbles inside and hemispherical pits on the surface. The outstanding feature of Tian Huangshi is that there are radish patterns, red plaid patterns or red rib patterns, but there is no imitation, and the transparency is uniform. Artificial imitation field Yellowstone has no stone skin, the color distribution is very uniform, the inside and outside are completely consistent, and it is thicker than natural products and unnatural.

Tian Huangshi's identification of authenticity mainly depends on the distribution of hue and color, the appearance and appearance of color aggregation.

Tian Huangshi has a variety of colors, all kinds of colors, and each stone color has a rule to follow. Then there is the texture, the feeling of seeing with eyes (observing the texture on the surface and inside of the stone), the feeling of touching with hands), the feeling of falling heavily, such as the heavy feel of stone products in puddles and old pits, the feeling of carving with a knife: the difficulty of eating a knife, whether it is smooth or not, the degree of astringency and so on; Tian Huangshi eats the knife smoothly.
