A visual observation of the surface structure of the stone
In general, the uniform fine material structure of the stone has a delicate texture, which is a good stone; the coarse grain and the unequal grain structure of the stone have a poor appearance. In addition, due to the influence of geological effects, the stone often produces some fine cracks in it. The stone is most likely to rupture along these parts, and should be removed. As for the lack of edges and corners, it is more important to affect the appearance, especially when choosing.

So as not to affect the splicing, or cause the pattern, pattern, and line deformation after splicing, affecting the decorative effect.
Three listen to the tapping sound of the stone
In general, the sound of a good quality stone is crisp and pleasing; on the contrary, if there is a slight crack inside the stone or the contact between the particles becomes loose due to weathering, the knocking sound is rough.
4. Try a simple test method to check the quality of the stone.
Usually a small amount of ink is dropped on the back side of the stone. If the ink is quickly dispersed and leached everywhere, it means that the inside of the stone is loose or there is a gap, and the quality of the stone is not good. Conversely, if the ink is not moved in place, the stone material is good.

Furniture Chipboard / Twinfast Screws, also known as particleboard screws. These self-tapping screws have a coarse thread with twice the thread pitch of standard Wood Screws, making it easy to drive them into a variety of materials such as chipboard or various densities of fibreboard. They can be easily inserted using ordinary hand screwdrivers or drive bits.
As chipboard does not have a natural grain this type of screw fixing is ideal, and the self-centring point helps the screws to start straight and drive true, with less risk of splitting.
