When the lava cooled, steam and other gases formed bubbles. The air bubbles are sealed when the rock freezes, creating many holes. After a long period of time, the silica-containing solution soaked into the pores and condensed into silica gel. The fusible components of the iron-bearing rock enter the silica gel, and finally the silica crystallizes into agate. It has a gelatinous texture, a hard texture and a variety of colors, usually green, red, yellow, brown, white, and other colors. The most common types are south red agate, candy gate, etc. The shape of agate is generally cylindrical and grape-shaped, with concentric waves on the surface, which is very popular among people.

When cutting semi-precious gemstone slabs, special cutting discs need to be purchased. The polishing of the edges can be performed in the same way as other standard granites.

Ammonia, bleach, or any other harsh cleaning agents must be avoided when cleaning semi-precious stones. Mild or neutral cleaning agents are suitable for cleaning semi-precious stones. Store the slate away from direct sunlight and avoid placing the slate at temperatures below 10°C (50°F) or above 40°C (104°F).

1) Look at the color. If natural agate and artificial agate are placed together, it can be clearly seen from the true and false, because the color difference between the two is obvious. The color of natural agate is relatively pure, and the color is relatively high, which is very attractive at first sight. There are some small dots densely distributed in the stripes on the surface, but there is no artificial agate stone. The color of artificial agate is darker than that of natural agate, and it looks Rather cloudy and not shiny.

2) Look at the texture. Artificial agate is generally made of stone, and its hardness is lower than that of natural agate. If jade is used to rub the two kinds of agate, the natural agate will not change, but the artificial agate will have scratches.

3) Look at the craftsmanship. The craft products of natural agate have stricter requirements in the production process, so the overall visual appearance of the finished product is relatively complete. There are generally no cracks, and the surface is relatively smooth.

4) Look at transparency. Although crystals are said to have high transparency, natural crystals are not absolutely transparent. Artificial agate has high transparency, while natural agate has some natural clouds inside, which should be distinguished.

5) Look at the weight. Natural agate is heavier than synthetic.

6) Sensing temperature. Natural agate will feel cool when you hold it in your hand at first, but it will be the same as your body temperature after a while, while synthetic agate is warm and moist without a cold feeling in your hand.

The distance should be minimized to prevent damage and cracking. For the countertop, the distance between the fulcrums should not exceed 30 cm.
