Glass is one of the most durable materials used in the kitchen. It is also one of the most common materials that are used in microwaves. It is used in over 90% of microwaves sold today. Glass is a good material for microwaves because it is non-porous and non-reactive, meaning that it does not interact with the food inside.
Glass also offers other benefits that make it worth using in your kitchen. For example, glass containers are usually more durable than plastic ones, which means they will last longer. Additionally, glass containers often have better clarity than plastic ones and allow you to see what’s inside without opening them up.
You want to enjoy some leftovers. But which dishware material can you use? You can’t go wrong with glass. Before microwaving your food, check what type of glassware you’re using.
Some people believe that glass is not microwave-safe. They think that microwaves can cause the glass to explode and break into shards. To know the truth, dig into this blog post and continue reading to avoid any hazardous situation.

Can You Use Glass in the Microwave?
There are many myths about microwaves and cooking. One of them is that you can not use glass containers in the microwave as it is not safe to use glass containers in the microwave because they can shatter and break, which could cause injury to anyone nearby.
However, this is not true. You can use glass in the microwave if it is heat-resistant and not made of low-quality glass.
The utensils you’re using shouldn’t make much difference, as long as they are labeled ‘microwave safe. This means the glass is designed to handle high temperatures, which most plastic and styrofoam containers aren’t. Gathering take-out in glassware is safer and better for the environment.
This is also true for other types of cooking – only cookware marked ‘oven-safe’ should be used in the oven.
What Type of Glass Can Not Be Used in Microwaves?
Microwave ovens are available to everyone; many find them useful for heating up or cooking food. They’re easy and fast, so you can use them when a microwave is the only option. I would recommend against using anything but plastic or metal containers inside the microwave. However, it has been suggested that glass containers might be microwave safe as long as they are not made of leaded glass. Glass is such a mixed bag; some claim it is acceptable to use, while others say you should never put it in the microwave.
Generally, anything that’s not labeled “microwave-safe” should be carefully inspected before microwaving. This is because the glassware may have metals and other materials, which can cause it to shatter or break in the microwave. Drinking glasses and glass containers are also a no-no, as they could explode at any point during microwaving.
Are All Glass Microwave Safe?
You may be surprised that not all glass products are safe for microwaves.
For microwavable containers, glass seems to be the more durable choice but will still break. The principal problem is that you are heating and cooling the container at high rates of speed, so it’s not indestructible. Most glasses are microwave-safe, but it is certified if you see a logo with a microwave symbol on your dish.
But if the dish doesn’t have a certified safe logo, it doesn’t mean it will break when microwaved, even if we place it inside our oven. Some kinds of Glasses can also break when cooled, so be careful when you take them out of the oven (they might snap if heated). Avoid microwaving any glass if you want it to stay intact.
Why Does Glass Shatter on Microwaving?
Why are some glasses microwavable and not others? Glass that is not microwavable has tiny air bubbles that can expand during the microwave process. If the air in a glass bubble expands too much, it will create excess pressure on the glass and break it.
Also, be careful with glass that is trimmed with metal. As you know, metal is not microwave-safe and can cause sparks when microwaved. This could lead to the glass breaking or becoming dangerous.
Make sure to check if your dish is microwave-safe. This can be done by looking for a label on the dish which will mention it is food safe and microwavable.
Can I Microwave a Cold Glass?
Before you put a dish or glass container containing food from the freezer into microwaves, you need to consider the following:
To avoid damage to your microwave or container, always allow frozen food to thaw before heating it in the oven.
The container will be damp when you take it out of the freezer, so make sure to wipe off any condensation before placing the container in the microwave.
When the microwave stops, do not forget to use pot holders or kitchen gloves to avoid getting burned by the remains of the food left in your dish. Make sure you pick up your container with pot holders or kitchen gloves for the same reason.
Yes, you can microwave a cold glass dish. The dish will not break from the microwaves, but it may crack if heated too high or too long. Glassware is microwave-safe up to 800 watts of power.
A microwave oven uses microwaves to create waves that penetrate the food and cause water molecules in the food to vibrate. This vibration creates heat, which cooks the food. If a cold glass dish is placed in the microwave, it will not be able to absorb any of these waves and, therefore, won’t heat up at all because there is no way for it to transfer its energy.
Microwave Glass Safety Test
Most dishes are now microwave-safe and can be checked by looking for a microwave-safe sticker. But if none is found, there is a way to test whether or not the dish can go in the oven.
The first step is to turn up your microwave oven to its highest possible power. The next step is to pour half a cup of water into a measuring cup or glass bowl and set it on the glass dish inside your microwave oven. Finally, ensure the glass dish is empty.
Both dish and cup need to be microwaved for 1 minute. The glass dish is not microwave-safe if the container becomes hot while the cup remains cold. If the dish remains chilled, but the cup has heated up, the glass dish is microwave-safe. Additionally, the area around the glass cups on this dish is slightly warm, but the rest remain cold to the touch and are safe for microwaving.
FAQ
Can I Use Pyrex Glass in the Microwave?
Pyrex is loved by many because it can withstand microwaves and ovens. Yes, Pyrex is microwave/oven-proof, but always be careful because of the risk of breakage.
Which Materials Should Never Be Microwaved?
Apart from some types of glassware, it would help if you never microwaved metal containers or metal objects (such as foil) in the microwave.
Other materials you should avoid microwaving are brown paper bags, dairy containers, Styrofoam cups and plates, and plastic wrap until it is labeled microwave friendly.
Final Thoughts
If your glassware has a label that claims to be microwave-safe, this is a reassuring detail! If you can’t find the label, always err on the side of safety and don’t cook with it. Avoid microwaving foods with metal edges, dyes in the glassware, or ceramic glass is always a good idea. Also, keep an eye out for any food heated up dramatically when microwaving.
If you’re unsure if the container is microwave-safe, use a different one that is clearly labeled to avoid any risks. It’s always better to avoid risks that can danger your life.
