What can’t be put in the microwave?

Now that people's material living standards have improved, more and more families have bought microwave ovens, which are very convenient and fast machines. The main function of microwave ovens is to help heat food. With the development of science and technology, today's microwave ovens are very powerful, energy-saving and environmentally friendly, and becoming more and more intelligent. So what can't be used in a microwave oven?

What can’t be put in the microwave?

1. Non-microwave-safe glass products, such as ordinary water cups, are at risk of bursting;

2. Foods with hard shells, such as eggs, cannot be placed directly in the microwave. The shells must be removed before use.

3. All metal products (including porcelain plates and bowls with metal edges) cannot be placed in the oven, because microwaves cannot penetrate metal materials and will rebound and cause sparks.

4. Wooden tableware should not be put into the microwave as it is likely to dry out and crack after heating.

5. Plastic products that are not specially made for microwaves must be heat-resistant at temperatures above 120 degrees, otherwise they will melt.

Taboos for placing items in the microwave

Lunch bags are not as harmless as they seem. Paper bags, plastic bags and newspapers cannot be put in the microwave. As the USDA report states, "They are unsafe, can catch fire, and can produce toxic gases. The high temperatures could ignite the paper bags, causing a fire in the furnace..."

Single-use plastic containers - such as yogurt, butter or cream containers - should not be placed in the microwave. They are truly disposable and cannot withstand high temperatures. Containers may warp or melt in the microwave, releasing chemicals into your food.

These things can't be microwaved.

1. Metal utensils

Microwaves cannot penetrate metal containers such as aluminum pots, enamel pots and stainless steel pots, and when they touch metal, sparks will occur on the inner wall of the oven, so they cannot be used. Note that using metal utensils can easily cause damage to the microwave oven.

2. Lacquerware

The lacquer on lacquerware may peel off or melt when heated, producing harmful substances, and the container may also crack, so do not use it.

3. Non-heat-resistant plastic containers

Ordinary plastic containers have poor heat resistance and cannot be used as microwave cooking utensils.

4. Non-heat-resistant glass containers

When food is cooked with oil, the temperature may be very high, which can easily cause the glass container to break, so non-heat-resistant glass containers cannot be used. Organic glassware should not be used.

5. Grass, willow, wood, bamboo, and paper products

These containers can be used when heated for a short time, but should not be used if heated for a long time as the containers may burn.
