How about a simple tiles? Good quality
"water". The water droplets on the back of the tiles, the water spread after the slow density of the tiles, as the top grade.
Are almost it, you can tell how to identify the quality of tiles:
The main production areas are: Guangdong, Shandong, Sichuan, Fujian. Look at the surface: mainly include, tiles, tiles, tiles, tiles, tiles, tiles, tiles, tiles, tiles, tiles, tiles, tiles (Except for special pattern processing, such as roller printing products, for the pursuit of natural stone texture effect), to see whether there is any difference between the color and the color performance (color) , Each piece of brick patterns are different.To see the texture of tiles: good products generally firing temperature is relatively high, the product is more compact, knock on the sound more crisp to see the size of the tile: size uniform, the size of each piece of brick Non-edging products should be less than 0.5% of the side length, edging products should be less than the side length of 0.2%.) See the brick flatness: take a few pieces of brick on a more standard plane, between the brick and brick Whether there is no obvious high and low deviation
"Look": a look level, the best of the best products, third-class goods and other goods are worrying; two look appearance and glazed, good tiles without drums, Qiaojiao and other issues, side straight, glaze Smooth, no particles or different shades of color phenomenon; three look at the pattern, the pattern should be delicate, no obvious color, dislocation, broken or different shades.
"listen". To one hand the thumb, index finger and middle finger folder tile corner, easy to hang, the other hand index finger tapping the lower part of the tile, such as the sound clear, sweet for the top grade, such as the sound boring, astringent turbidity for the defective.
"cut". Cut out the tile cut (usually to the store to have broken pieces of observation), see the break at the Department. Broken at the fine, hard and brittle, consistent color for the top grade.
