1、 Is glass cutlery safe

Glass is an inorganic non-metallic material with a wide range of applications, and it is one of the common uses of glass for tableware. Many friends are concerned about the safety performance of glass tableware. In fact, glass tableware produced by legitimate manufacturers is quite safe

Glass tableware commonly uses several types of glass, such as silicate glass, borate glass, and aluminate glass. Their raw materials are basically mineral materials such as silica, calcium oxide, and alkaline oxides, with stable properties. After special treatment, the melting temperature of heat-resistant glass tableware can reach as high as 1100~1800 ° C, which is very safe for normal use in daily life.

It is not worth noting that glass tableware is not entirely reliable. In specific environments where glass is immersed in water for a long time, it can be corroded by water. The sodium silicate in it reacts with carbon dioxide in the air to generate white carbonate crystals, which are harmful to human health. Therefore, we need to master the correct usage methods when using glass tableware in daily life.

2、 How to safely use glass tableware

Glass tableware is clean and hygienic, free from toxic substances, and is a commonly used type of tableware. Its disadvantage is that it is fragile, and if used improperly, it can easily cause glass to burst. Therefore, when using glass tableware, attention should be paid to:

1. When glass cutlery is placed in the freezer, the volume of food contained inside should not exceed two-thirds of the cutlery. If it is closed or semi closed, it should avoid containing juice, broth, milk, Congee and other liquids, so as to avoid the expansion of food volume after freezing and damage of glass tableware.

2. When heating glass tableware in the microwave, be sure to open the lid. Although the box cover can be placed in a microwave oven, it is susceptible to thermal expansion and contraction, which can cause problems such as inability to open or deformation of the box cover after heating, affecting the sealing of the product.

3. Be cautious when using a base pot to heat glass utensils, such as steamed fish, steamed egg custard, etc., as the pressure of the steamer can easily react with the heat resistant glass, causing slight cracks in the glassware

4. When cleaning glass tableware, attention should be paid to avoiding scratches by using steel wire balls for cleaning

5. Glass is fragile, so when using glass tableware, it should be handled with care and avoid hitting it with hard objects such as steel spoons to avoid breakage

The above are the precautions for using glass tableware. Under normal use, glass tableware is still relatively easy to use.
