Why Glass Bowl Can Not Be Put In Microwave

One customer told us his confusion yesterday。He said, I was shopping in the supermarket and a large transparent glass bowl as gift.  

It's about the same thickness as my white bowl. It's mainly made of soup. I put the leftover food in the microwave oven for just ten seconds, and then I heard the cracking sound. Turn off the power and turn it on. It really broke in two. It is ok with my that white bowl. I always put it in the microwave. 

Why some glass bowls can’t be put in microwave?

The glass bowl can be heated by microwave. Not only the glass bowl can be used, but most of the glassware can be heated in the microwave oven, including the glassware made of borosilicate glass, microcrystalline glass and titanium oxide crystal glass. 

Due to the good microwave penetration performance, stable physical and chemical properties, and high temperature resistance, it is suitable for long-term use in the microwave oven. It is suitable for use in microwave oven for a long time because of its good penetrability, stable physical and chemical properties and high temperature resistance.

In modern society, people need to use a lot of glass products in their daily life, which has been completely unable to get rid of glass. Glass is stable, acid and alkali resistant, hard and durable. It is one of the raw materials for most important equipment. Want to know more about whether you can put glass bowls in the microwave oven for heating, and what kind of containers can be used in the microwave oven.

What kind of container is suitable for use in microwave oven?It is important to master three elements: 

A.strong penetration of microwave oven

B.high temperature resistance

C. food hygiene requirements

1.Glass bowl 

Glassware made of borosilicate glass, microcrystalline glass and titanium oxide crystal glass. Due to its good microwave penetration, stable physical and chemical properties, and high temperature resistance (up to 500 ℃ or even 1000 ℃), it is suitable for long-term use in microwave oven. Glass, milk bottle and nursing bottle made of ordinary glass are only suitable for short-term heating in microwave oven, About 3 minutes. If heating for a long time, it is easy to crack. Carved glass, reinforced glass, crystal glass products, due to the uneven thickness of materials, will burst when cooking oily food, not suitable for use in microwave oven.

2.Ceramic bowl

it can be divided into heat-resistant ceramics and ordinary ceramics. Pots, plates and other utensils made of heat-resistant ceramics are suitable for long-term use in microwave ovens, while ordinary ceramic utensils can only be used for short-term heating. It should be specially reminded that ceramic utensils containing gold and silver wires will spark when used in microwave ovens, so they are not suitable for use.

3.Plastic bowl

 All kinds of utensils made of polypropylene, polypropylene resin, composite polypropylene, polysulfone and other materials, with temperature resistance of more than 120 ℃, can be used for microwave heating. Utensils made of PET resin and polyester materials, with temperature resistance of more than 220 ℃, can be used for barbecue. The fresh-keeping film also belongs to plastic products: one is common fresh-keeping film, which can be used when heating vegetables; The other is a special fresh-keeping film for microwave oven, which can be used to heat meat, poultry and sugar food. As for the non heat-resistant containers such as polyethylene, styrene, phenol and melamine, they must not be used in microwave oven, because these materials can melt when heated, and some will emit toxins and peculiar smell, which is harmful to human heal.

4.Metal bowl

all kinds of utensils made of aluminum, stainless steel, enamel and other metal materials. Microwave can't transmit through metal. The bright metal surface can reflect microwave. The non transmission and reflection of metal container make it impossible for microwave to reach its interior and heat food. At the same time, the mutual reflection between the container and the inner wall of the furnace will cause eddy current and ignition of some metals, It's very dangerous! So it's not suitable for microwave oven

Before putting the glass bowl into the oven, it is necessary to distinguish what glass it is. If it is heat-resistant glass, it can be used in the oven, with reliable safety. However, ordinary glass or toughened glass can not be used in the oven, or there will be a risk of self explosion! So when buying glass products, you should see the glass materials clearly. That's how you use it.
