<p>of identification of all ceramic tiles. &amp;nbsp; &amp;nbsp; a look (1) look at the appearance, the surface of all ceramic tiles to uniform color, bright and clean, flatness is better, around the rules, no color difference, deformation, lack of edges and corners and other defects. (2) see section, section was divided into two layers is not all ceramic (3) look at the weight, the general weight of the ceramic tile because the processing time to join the glazed tiles are so heavy, if not all </p>
<p>ceramic tiles on the light. Two (1) to listen to the sound, with a hard object tip, the sound is more crisp, the higher the degree of porcelain, the better the quality. (2) with one hand hanging tiles filed the edge or corner, easy to hang, on the other hand on tile, a deep and long echo tiles (such as issued by the sound of knocking Bell) for all ceramic tiles; such as sound or no echo echo turbidity is smaller and shorter description the degree of porcelain tile poor embryo </p>
<p>material particle size tiles are less dense, such as ordinary semi porcelain brick. &amp;nbsp; &amp;nbsp; three drop due to low water absorption ceramic floor tiles, floor tiles in turn, in the back drop of water, see the speed of water infiltration, spread out in general, water more slowly, indicating that the tile density is higher; on the contrary, water more quickly, that the density is sparse, the intrinsic quality is superior to the former. Four feet of the precision of the ceramic tile </p>
