1. Be sure to buy tempered glass basins and glass countertops, because tempered glass has several characteristics: high temperature resistance, impact resistance, and no injury (rounded glass particles after breakage). 2. The thicker the glass is, the better the sink is. In fact, the thicker the glass basin is, the slower the heat transfer rate is when it is loaded with hot water. At this time, the internal and external temperature difference will be formed. The glass basin will be hot. Under the effect of expansion and contraction, cracks appear as if the ice is placed in boiling water. The greater the temperature difference, the more severe the rupture may be. 3. When choosing a glass wash basin, care should be taken to ensure that the edges of the pots and pot holders are rounded and that the edge-cut products are unqualified products. It is also possible to distinguish the quality of the wash basin from whether or not the glass contains air bubbles, and only bubbles exist in the glass of the inferior glass wash basin. glass insect control ,Termite Killing,Pest Exterminator ,Pest Removal Pesticide & Insecticides Co., Ltd. , http://www.nbfungicide.com
