Microwave safe glass – can glass go in the microwave?

Generally, all Heatproof glass and Glass-ceramic containers are safe for use in the microwave. You can usually microwave anything which is pure glass, but glass cups or plates with metal rims should be avoided.

I have posted in the above image a type of glass container that you can usually use for microwaving. This is Heatproof glass. It is generally labelled microwave safe and can also withstand hot soups or curry if they are placed in it.

Notice the thickness of the containers. It is usually a better idea to put only thick glass in the microwave as it can always withstand heating to high temperature.

Can I use glasses with embossed imagery?

No, you should not use glass containers with embossed designs and patterns. This type of glass is usually weak as the embossing takes away huge chunks of glass to etch the designs. The areas with low glass material will crack and the glass object may even shatter in the microwave.

Can I use glasses with metal?

No, you should absolutely not put in any glass material with metal. Thin Metal will usually heat up first while microwaving. Usually, the glass cups and containers have metal rims and designs. Hence this type of metal contains thin pieces that are usually ornamental and thus can cause fires.

Can I use glasses with printed images?

No, it is not a good idea, especially if the printing is on the inside of the container. Microwaving will heat up the printing inks and can mix with the food. As most inks are usually not safe for consumption you will have to throw the food out.

Can I use glass with no microwave-safe tag?

Yes, you can. If it is a thick glass container it will not shatter. But objects made of thin glass will usually shatter.

Can I use Non-heatproof glass?

Yes, you can if it is thick enough. Glass usually doesn’t heat up in the microwave.

Can I use Glass-Ceramic containers?

Yes, you can. Glass-Ceramic containers are safe for use in the microwave. An example of this would be Corning Ware.
