he common glass products for food contact in our daily life are mainly divided into two categories: bottles, cans and utensils.

As the world's largest glass producer and consumer, my country's food-related glass products cover all aspects of our daily life. Here are some tips for 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 prone to damage 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 gradually 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 temperature difference range. In the process of scalding wine, the temperature difference is large when adding hot water, which is prone to rupture. It is recommended to use heat-resistant appliances for heating when scalding wine to avoid damage to the wine bottle and spillage of wine.
2. Avoid collision and impact: Glass products should be prevented from colliding with each other or other hard objects; especially unopened beer bottles and carbonated beverage bottles, under the influence of the contents, are likely to burst and even cause personal injury.
3. After use, it should be cleaned and dried in time to prevent dirt from depositing.
4. For cleaning, avoid using steel balls and other tools that are easy to scratch the glass. It is recommended to use nylon cloth or sponge to wipe in warm water to prevent the glassware from being ground and affecting the transparency.

1. Check the logo and trademark to determine whether to mark the manufacturer's information.
2. Check the appearance. The appearance of glassware should be smooth, transparent, without cracks, scratches, dirt, burrs and bubbles that affect the appearance.
3. The product type should be applicable. If it is only used at room temperature or room temperature, ordinary products can meet the requirements. If you need to hold hot food or heat it in a microwave oven, you need to choose heat-resistant glass utensils. If consumers find the nominal heat-resistant glass but the price is very low when purchasing, they should consider its authenticity. It is also possible to preliminarily judge whether it belongs to soda lime glass or heat-resistant glass by observing the clarity, fineness and roughness of glass products. Glass.
4. In order to meet the needs of consumers for appearance, there are many colorful glass products on the market. In simple terms, colored glass is the addition of colorants in the production process of glass, such as gold, silver, copper, selenium, sulfur, etc., Small particles are suspended in the vitreous body to color the glass, and the added colorant is relatively stable in the vitreous body and will not precipitate toxic and harmful substances. When purchasing colored glass products, it is necessary to distinguish between colored glass products and color printing and painted glass products. Color printing, painting and color glaze are usually on the surface of glass products, and heavy metals are more likely to migrate into food. Consumers are advised to try their best to purchase colored glass products. Choose clear, unadorned glass products.
