Natural stone grain 1. More options 2. Hardness is 3. High density 4. Wear-resistant nature. Its disadvantages: the natural stone is relatively heavy, and the gap between the two pieces is large, so it is difficult to connect and seamless splicing; Permeability is also high, and stains are difficult to clean. Insufficient elasticity, heavy impact will produce cracks. If you choose natural stone as the countertop, the disadvantage is that the length is required. If it is too long, the splicing can't be as seamless as artificial stone. In addition, natural stone has pores, so it is good to choose dark granite (granite) when making cabinet countertops, and obviously you can't buy any artificial stone at this price.

Artificial stone: it is a kind of mineral-filled polymer composite material (referred to as solid surface material or solid board for short, commonly known as artificial stone) made of natural mineral powder, high-performance resin and natural pigment by vacuum casting or molding.
