Identify the Quality of Ceramic Bathroom Sink

Appearance Inspection

Glaze finish, brightness: Good glaze finish and brightness, pure color, not easy to hang dirt, easy to clean, long-term use is still bright as new. When judging, you can choose to observe from the side of the ceramic from multiple angles under a stronger light line. A good glaze should have no stains, pinholes, sand holes, or bubbles, and the surface of the bathroom sink is very smooth. The light reflection is good and uniform.

Texture Touch

You can use your hand to touch the surface of the ceramic bathroom sink gently, good hand sensing is very smooth and delicate, and even the back of the basin is smooth and neat, and the good glaze is smooth and smooth to touch.

Sound Test

Use the hand to knock the surface of the ceramic bathroom sink, the sound of the good ceramic material is very crisp. If the beating sound is not clear or low enough, then the porcelain basin will be defective, or the basin body hidden internal cracks, convulsions and other limitations.

Water Absorption Index

The so-called water absorption rate is an indicator to judge the adsorption and permeability of ceramic products to water. It is understood that after water is sucked into the ceramic, the ceramic will produce a certain expansion, which is easy to crack the enamel on the surface of the ceramic due to expansion. It can be seen that the lower the water absorption rate of ceramic products, the better the quality. According to the relevant national water absorption standards, sanitary ceramic bathroom sink with a water absorption rate of less than 3% are high-grade ceramics. When purchasing, we should pay more attention to the manufacturer’s instructions, and try to choose products with low water absorption.

Art Basin

If it is an art basin, you also need to pay attention to the process, pattern, color: most of the high-grade hand-painted table basin are using under glaze color ceramic process, which is also the best ceramic process at present, so pay attention to distinguish when purchasing, to prevent illegal dealers from pretending to be under glaze color.      

Under glaze decoration pays attention to meticulous brushwork freehand style, must be hand-drawn, not printed, applique, and the color should be bright. It should be reminded that the hand-painted bathroom sink, because of its manual production, different from the machine mass production, the production method and style are different, the effect of the same group of patterns are slightly different, should be observed carefully when buying. Products in the high temperature firing process, due to the use of color glaze kiln change, each product will appear a certain color difference, color glaze glaze surface will appear small cracks, which is the color glaze manual products for thousands of years, so it will not affect the overall effect.
