How to distinguish whether heat resistant milk Coke tea double layer cup is made of crystal or glass
Time of issue:
How to distinguish between crystal and glass materials, heat resistant milk Coke tea double layer cup summarizes the following points for you:
1. Wipe or clean the heat resistant milk Coke tea double layer cup to be identified. After drying, touch the crafts with the tip of your tongue. If it feels cold, it is a crystalline product, and if it feels warm, it is a glass product. During the test, try not to grasp the sample with your hands or place the sample near a heat source (in the sun, next to the stove), so as to avoid errors caused by the increase in sample temperature.
2. Use a magnifying glass to observe the heat resistant milk Coke tea double layer cup. Inside the glass, vortices or curved lines are often generated due to uneven melting, but there are no crystals at all. In addition, there are usually many bubbles in glass and few crystals.
3. For the crystal heat resistant milk Coke tea double layer cup, you can put it on the newspaper, and then read the following newspaper from the top of the crystal heat resistant milk Coke tea double layer cup. If it is a real crystal, the text on the newspaper will have a double shadow. For glass products, there is always only one handwriting image on the newspaper.
The main body of the heat resistant milk Coke tea double layer cup is made of high-grade crystal glass through advanced technology. The 640℃ high-temperature firing process has reached the critical point of crystal glass melting. It is transparent, pure and harmless. At the same time, the annealing process is adopted to ensure that the cup body can withstand the instantaneous change of cold and heat, explosion-proof, anti-crack, no tail vacuum, high transparency, strong crystallization, wear resistance, and high temperature resistance.
