Glassware includes glassware made of borosilicate glass, microcrystalline glass and titanium oxide crystalline glass. Because of its good microwave penetration, stable physical and chemical properties and high temperature resistance (up to 500 degrees Celsius or even 1000 degrees Celsius), it is suitable for long-term use in microwave ovens.
The material of the glass itself comes from nature, and the harmful substances have volatilized after high temperature in the production process, so the glass has high safety, high temperature resistance and good thermal conductivity, and is suitable for microwave cooking.
Improper use of stainless steel tableware is harmful to human health.
Many consumers like stainless steel kitchenware and tableware very much. Because of its good metal properties, compared with other metals, it has corrosion resistance, and the utensils made are beautiful and durable, which are more and more used to make kitchen utensils. However, stainless steel is made of iron-chromium alloy mixed with other trace elements. If it is not used properly, its trace metal elements will gradually accumulate in the human body, which will endanger human health when it reaches a certain limit.
Ceramic containers have a wide range of uses, such as acid resistance, alkali resistance, oil resistance, high temperature resistance, low temperature resistance and high safety, and can be used for microwave cooking. However, it should be noted that the paint on colored ceramic containers may contain harmful substances such as lead and cadmium. Ceramic products are divided into three types according to their different decoration methods: over-glaze color, under-glaze color and in-glaze color. The underglaze color and the underglaze color are both painted under the enamel color, and the painted color is not in direct contact with food, so it is relatively safe. On the other hand, glazed ceramics are painted on the surface of ceramics and are in direct contact with food. Harmful substances such as lead and cadmium will enter food and enter the human body with food. If consumers can't clearly judge the glaze color type of ceramic tableware, for safety reasons, it is best to choose a ceramic container with a white achromatic color pattern on the inside of the container.
