Common sense of daily use and purchase of glass products in contact with food
Glass products commonly used in our daily life for food contact are mainly divided into bottles and containers. Glass bottles and containers are mainly transparent containers made of molten glass by blowing and molding. It is mainly used for packaging liquid, solid drugs and liquid drinks. Common glass bottles mainly include white wine bottles, beer bottles, wine bottles, beverage bottles, food cans, etc; Utensils in contact with food refer to glass utensils containing food and beverages, such as cups, dishes, bowls, plates, cups, etc，glass cookware .
As the largest glass producer and consumer in the world, China's food related glass products cover all aspects of our daily life. Here are some tips on the daily use and purchase of glass products.
1、 Due to the stability of the glass material itself, there is generally no shelf life. However, glass products are easy to be damaged during use, so the following points should be noted:
1. Avoid strong thermal shock. When adding high-temperature food to glassware, it should be added step by step so that the glass can adapt to the temperature difference; For example, the glass used in general wine bottles is soda lime glass, which can withstand a small range of temperature difference. During the process of using wine bottles to warm and scald wine, the temperature difference is large when adding hot water, which is easy to crack. It is recommended to use heat-resistant appliances for heating when scalding wine to avoid damage to wine bottles and spillage of wine.
2. Avoid collision and impact: glass products shall not collide with each other or with other hard objects; Especially the unopened beer bottles and carbonated beverage bottles are easy to burst and even cause personal injury under the influence of the contents.
3. After use, it should be cleaned and dried in time to prevent dirt deposition.
4. It is recommended to use nylon cloth or sponge to wipe in warm water to prevent glassware from being scratched and affecting transparency.
2、 Consumers should pay attention to the following points when purchasing glass products
01
Check the logo and trademark to determine whether the manufacturer information is marked.
02
Check the appearance. The appearance of the glassware should be smooth, clean, transparent, free of cracks, scratches, dirt, burrs, bubbles and other defects that affect the appearance.
03
The product type shall be applicable. If it is only used at room temperature or room temperature, ordinary products can meet the requirements. If it is necessary to hold hot food or heat it in a microwave oven, heat-resistant glass utensils shall be selected. If consumers find that the nominal heat-resistant glass is low in price when purchasing, they should consider its authenticity. It can also be preliminarily judged whether the glass products belong to soda lime glass or heat-resistant glass by observing the clarity, fineness and roughness of the glass products. The glass with poor clarity, fineness and roughness is generally soda lime glass, and the glass with poor clarity, fineness and roughness is heat-resistant glass.

In order to meet the consumers' demand for appearance, there are many colorful glass products on the market. In brief, colored glass is added with colorants, such as gold, silver, copper, selenium, sulfur, etc., in the production process of glass, so that smaller particles are suspended in the glass body and the glass is colored. The added colorants are relatively stable in the glass body and will not release toxic and harmful substances. When purchasing colored glass products, attention should be paid to distinguishing between colored glass products and color printing and painted glass products. Color printing, color painting and colored glaze are usually on the surface of glass products, and heavy metals are more likely to migrate to food. It is recommended that consumers try to choose transparent glass products without decorative layers in the purchasing process.
