Touch the surface.
When purchasing culture stones, you can touch the surface with hands to see if there is powder on hands. If there is powder on hands after touching, such culture stones are inferior. However, high-quality culture stones will not have similar situations after being touched.

Look at the back side.
Look at culture stones texture and the back side. Some people ask what can be seen from the back? We can judge the quality of culture stones by the uniformity of particles on the back. Culture stones with smooth surfaces and uniform particles are of good quality.

Look at the surface pattern.
The culture stones we purchased are basically artistic retro simulations, and from a distance, there is nothing wrong with them. The surface patterns of culture stones of not too high quality are carved very finely and realistically, and the patterns on the top are not repetitive.

Look at the cross-section of culture stones.
To buy culture stones well, we can cut them in the middle to see the density and solidity of their cross sections. After opening inferior culture stones, the particles inside will be very loose and not solid at first glance, and there will be large gaps between the particles, and the color will also be very light. While high-quality culture stones do not have too many gaps in the middle, they are strong and durable.

Observe the corners.
If the quality of the culture stones we purchase is good, their edges and corners will be polished more smoothly, and the manufacturing process will also be more beautiful. They will not be scratched during installation, bringing convenience to the construction personnel. Moreover, when buying cultural bricks, we can choose thicker culture stones, which will make the indoor space more three-dimensional when pasted on the ground or walls.
