Can you put the glass in the microwave? Yes, you can as long as you take the proper precautions.

A microwave without a doubt makes lives a lot easier. You can go from a frozen ready to cook meal to a cooked dinner in less than five minutes. With a microwave, you have the power of cooking almost anything at the tip of your fingers.

The convenience a microwave brings should be combined with responsibility.  This kitchen appliance can make or break your dinner depending on what you put in the microwave.

How to know if Glass is Microwave Safe

Although glass can go inside the microwave, not all glass is made for such use. The safest way to know if the glass you are holding can safely be used in the microwave is to check if it is labeled “microwave safe.” This label can usually be found at the bottom of the glass dish.

If glassware does not come with a “microwave safe” label, does it mean that you cannot put it in the microwave? No because in most instances you can still put that glass in the microwave.

While most glasses are safe to use in the microwave, you can subject it to a test:

  1. Pour some water into the glass, glass dish or bowl.
  2. Put it in the microwave and set timer to one minute.
  3. Remove the glass, glass dish or bowl.
  4. Dip your finger on the water and feel the glass.
  5. The glass, glass bowl or dish should be cooler to the touch than water inside for them to be “microwave safe.”

It is good to know that most glass cookware and bowls are made of tempered glass. This means they can withstand high temperatures. This also means that should the glass break, it will not shatter into tiny pieces but will break into large chunks of glass making it safer to deal with.

Precautions to Take when Putting Glass in the Microwave

While glass can withstand high temperatures making it safe to use in the microwave, it is vulnerable to extreme changes in temperature or temperature shocks. Temperature shocks can cause the glass to break.

Here are some precautions to take to prevent the glass from temperature shocks:

  • If the glass is coming from the freezer, allow it to cool down to room temperature before placing in the microwave. Not doing so may cause the glass to break or explode even if it is made from tempered glass.
  • Never place in the microwave glass, glass dishes, or glass bowls with metal inlays or trims.
  • Avoid using glass with breaks or cracks in the microwave. These cracks weaken the glass and may cause it to break once heated. The portions of glass with cracks will heat faster than the other portions of the glass which may lead to a disaster.
  • Never heat food for too long.
  • Never place glass, glass bowls, or dishes you just took out of the microwave on anything that is cold.

Glass is a better container to use in the microwave than plastic because it does not contain any harsh chemicals that can leech out when heated.

Can glass go from fridge to oven?

It would almost certainly be OK, but to be on the safe side I’d put it on a room temperature baking sheet (ideally quite a thick one) before putting it in the oven. This will avoid the thermal stress caused by the bars of the shelf.

What temperature will crack glass?
