(2) Tongue licking: Even in the dog days of hot summer, licking the natural crystal surface with the tongue also has a cold and cool feeling. Fake crystal, there is no cool feeling.

Check the connection between the curtain wall and the main structure of the building. Check the specifications and quantity of connectors, insulation sheets, and fasteners. Where anchor bolts are used for anchoring, check the type, specification, quantity and layout of anchor bolts.

While some natural glass does exist in nature, such as black stone and talc, the vast majority of glass is fired by humans at high temperatures. As far as we know, the origin of glass dates back to the Bronze Age of Mesopotamia. About 4,000 years ago, humans began melting silica (sand or crushed stone) and mixing it with small amounts of limestone and soda ash. According to Pliny, the invention of glass was a happy accident: the Roman historian suggested that glass was accidentally acquired by Phoenician sailors in the course of a beach picnic, but since there were no flames at the time capable of reaching temperatures high enough to melt sand, this view is questionable. Contemporary historians believe that glass may have been discovered in the process of making ceramics or working metals. These two processes require higher firing temperatures and longer firing times than baking bread or roasted leg of lamb.

(7) Check with a magnifying glass: check with a 10x magnifying glass under transmitted light, and the bubbles that can be found can basically be defined as false crystals.

Benefits of Tinted Tempered Glass

Decorative glass panels for walls can add a touch of elegance and beauty to any space. Whether you are looking to add a unique design element to your home or office, decorative glass panels are a versatile option that can enhance the overall aesthetic of a room.

Low-E2 glass, or low-emissivity glass, features a microscopically thin, transparent coating that reflects heat while allowing visible light to pass through. This unique characteristic makes it an ideal choice for energy-efficient buildings. Unlike traditional glass, which transmits both heat and light, Low-E2 glass effectively minimizes the amount of infrared radiation that can penetrate through windows and doors. As a result, buildings equipped with Low-E2 glass can maintain more stable indoor temperatures, reducing the reliance on heating and cooling systems throughout the year.
