Are Glass Dishes Microwave-safe In General?

In our homes, several dishes such as bowls and plates are used in the microwave. However, caution has to be taken to choose the right type of dishes to use in the microwave. If you are wondering whether glasswares are safe to use to heat food in the microwave; the answer is yes.

However, glassware that has tiny air bubbles are not safe to use in the microwave because the heat could be expanded through the tiny air bubbles which cause the glassware to explode inside the microwave.

Also, Glasswares that have metal components on it should not be used because the metal could cause a spark which would lead to the glass dish shattering inside the microwave.

What Are Glasswares?

The term glassware is made up of two words glass and ware. Glass refers to a hard brittle substance, commonly transparent, which generally consists of dissolved silica and silicates (soda and lime).

On the other hand, ware could be referred to as any tangible object made up of a particular substance. Put together, glasswares are cutleries or dishes made up of glass components. Aside it being used as kitchen utensils, it can be used to make tables, windows and other objects.

Glasswares such as cups, food storage containers are most times placed on the dining table or kitchen and also used in the preparation of foods. Glasswares can be used for drinking, storage, cooking, reheating or warming food.

What Are The Different Glasswares That Are Available

In case you have not noticed, there are different types of glassware which can be used for heating or food storage. For someone who has no idea, it may not be easy to differentiate by just looking at them. But that’s fine, it quite easy to tell them apart once you see the glass-make as written by the manufacturer. So, let me share the major types and show you what makes them different. This way, you would know what to do with each one you may have. They are:

  1. Borosilicate Glassware: These are products made up of borosilicate glass materials. The borosilicate is a type of glass comprising of silica and boron trioxide. Products made with this type of glass are more resistant to temperature shock than any other common type of glass. The borosilicate glassware can be used for various purposes such as cooking, lab equipment and medical services.
  2. Pyrex Glassware: The pyrex glasswares are those type of glass materials that can be used for cooking, reheating or warming and baking. Pyrex glassware is usually dishwasher safe and you can also easily wash it using your hands with the aid of non-abrasive cleaners, plastic or pads made with nylon. The pyrex glasswares are products commonly used in the kitchen for heating or cooking. They can be used in the oven and microwave because they are much stronger than the regular glass.
  3. Simax Glassware: Food containers made up of simax glass are suitable for fridge, freezer and heat sources. The simax glassware can be used in the oven and microwave. The nature of the simax glassware makes it possible for it to be used on the electric, gas and glass-ceramic hot plates.
  4. Soda-Lime Glasswares: The soda-lime glass is generally regarded as safe for food storage and beverage products. It can be used on an electric pot, microwave or oven because it is made up of heat resistant components but cannot withstand EXTREME heat.


How To Know If Glass Utensils Are Safe For Microwave

Knowing if glass utensils are safe for your microwave is of great importance because you would not want to damage your microwave or cause any type of accident as a result of an explosion. There are easy steps you can use as a test to check if glass utensils are safe for your microwave. The steps include the following:

  1. Fill the glass dish with water. Put the filled glass dish into the microwave. You should first of all check for the safety indicator on the glass dish to be sure it is safe for use in the microwave. The manufacturer usually indicates with a label at the bottom of the glass dish to indicate whether the material is safe in the microwave. So, ensure you read the label for safety precaution.
  2. Switch on the Microwave with the filled glass dish inside: Ensure the glass dish can properly fit into the microwave. Then increase the heat level from the microwave buttons to a considerable level and wait for a minute (or 2 if your microwave doesn’t heat fast).
  3. Remove the water and check the temperature of the water: Turn off the power button of the microwave and use a potholder to remove the glass dish filled with water. This is where you do the main test by checking for the following:
    – You should take important note by observing if the microwave and the glass dish/bowl is warm or hot, but the water inside the glass dish is cold. If this happens, it means it is unsafe. A warm dish signifies that it can absorb heat. And by absorbing heat, it can explode easily.
    – The glass dish is safe to use in the microwave if it is cool and the water is warm. This implies that a cool dish means it doesn’t absorb heat.
  4. Mark or label your glass dish: If you have a lot of glass dishes, you can carry out this test on all your glass bowls to see which one you can use in the microwave. Putting marks or labelling a glass dish would help you know the dish that is safe for the microwave so that you don’t end up blowing up your precious dishes. You can use a permanent marker to label the bottom of the glass dish based on the result of your test. Do not forget to label the glass dish and you can use any method. For example; you can mark with the letters SM which could mean Safe for Microwave. Or you use two lines (=). Just anything that would help you or others in the house know which to pop into the microwave.
12 Important Tips to Consider when buying Glasswares

There are some important factors to consider when selecting glassware to use, whether it is for storage, cooking or heating. If you are looking at getting the best glassware for your kitchen to be used in the microwave, here is a buyer’s guide with a. some important tips that would guide your buying decision:

  1. Look out for the size of the glassware. Ideally, it is good to buy glassware that can easily fit into your microwave.
  2. The cost of the glassware should be considered. The price tag on the glassware product shouldn’t cost you all your savings. Go for the one that is good and yet, does not cost so much. However, if you can afford something higher, then go for it as long as it has all the qualities you are looking for in a good microwave-safe glassware.
  3. The quality of the glassware is of great importance. You should select glassware that is thick enough and would stand the test of time (or your microwave in this case).
  4. The durability of the glassware should be considered. Select glassware that has a long-lasting lifespan. It is unwise to keep buying glasswares repeatedly over a short period of time, so you must go for a brand that delivers durable ones.
  5. Pick one that is not susceptible to cracking. Look at the rims and edges of the glassware; glassware designed with rolled edges and rims would reduce chipping and cracking problems.
  6. Avoid stemmed glasses because it could easily be broken. If at all you opt for stemmed glass, make sure the designs are harder to tip over.
  7. Select glasswares that are airtight and watertight. Food stored in this type of glassware would hardly leak.
  8. You have to consider the versatility of the glassware. Go for glasswares that you can easily use in microwave, oven or that can go directly into a heat source without causing much (or any) harm.
  9. You have to consider value for money. Buy glasswares that can satisfy your needs or demand.
  10. Look out for the weight of the glassware. Is it what you can easily carry when food is stored inside? Can your kids (if any) comfortably carry it around when they want to help in the kitchen? If the dish is lightweight enough and still strong, then it’s a good option. But you can choose something heavy if that’s fine with you.dishwasher-safe-glasswares-for-microwave-oven
  11. You should also consider the washing of the glass dishes. Select glassware that is dishwasher-safe or can be cleaned easily without much stress put into washing.
  12. Take out time to read the manual which contains the manufacturer’s instruction on the particular product. Try to find out if such glassware can be used in the oven, microwave, and electric hot plates or can be stored inside the fridge or freezer. This would save you money, energy and the shock of opening your microwave/oven and coming face to face with shattered glass.
