1. Look and feel
When choosing and purchasing, first of all, like ordinary white ceramic table basins, we should pay attention to glaze smoothness and brightness. Good glaze finish and brightness excellent, pure color, not easy to hang dirt and scale, easy to clean, long-term use is still bright as new. When judging, it can be chosen to observe from the side of the ceramics in a strong light from multiple angles. A good glaze should have no stains, pinholes, sand holes and bubbles, and its surface is very smooth. It has good and uniform reflection of light. It can also be touched gently with hands on the surface, and the hand feeling is very smooth and delicate.

The so-called water absorption rate is an index to judge the ability of ceramic products to absorb and penetrate water. It is understood that after water is absorbed into ceramics, ceramics will expand to a certain extent, and the glaze on the surface of ceramics will easily crack due to swelling. Thus, the lower the water absorption, the better the quality of ceramic products, so try to choose products with low water absorption. According to the national standard, sanitary ceramics with water absorption less than 3% are high-grade ceramics.

When choosing and purchasing glass basin, we should make sure whether it is toughened glass. True toughened glass can be knocked by blunt instrument, and ask the merchant to show the relevant proof.

2. Consider the actual situation of bathroom
When choosing a basin, first of all, we should consider the installation environment of the Space University in general, when the width is less than 70 cm, it is not recommended to choose the basin on the platform. Because the platform basin wants to be installed within 70 centimeters, there are few kinds of products that can be selected. After installation, it will appear cramped and the visual effect is poor.

In addition, before choosing and purchasing, you should also consider the location of the water supply and drainage pipes at home, refer to the space environment around the water supply and drainage pipes, and match the basin. When purchasing art bowls and basins, we should also take into account the height of the faucet and other issues, so as to prevent the use of the basin from being too low.

3. Technology, pattern and color
Most of the top-grade hand-painted tables and basins are made of underglaze colored ceramics, which is also the best ceramic technology at present. Therefore, attention should be paid to distinguishing when choosing and purchasing. Underglaze decoration pays attention to meticulous freehand brushwork, must be hand-drawn, not printing, decals, and bright color. In the process of firing at high temperature, each product will have a certain color difference due to the use of color glaze kiln. Small cracks will appear on the glaze surface of color glaze. This is the characteristic of color glaze handicraft products for thousands of years, so it will not affect the overall effect.

In addition, as a high-quality ceramic basin, after tapping gently with your hands, you can also hear a crisp and loud knock. If the voice is hoarse, the surface of the product has cracks, the best look is inferior.

Maintenance of artistic bowls and basins on stage

In addition to cleaning in accordance with the above methods, glass basins should not be cleaned with boiling water, cleaning cloth, steel brushes, strong alkaline detergents, hard sharp tools, etc.
