What is Corelle?
Corelle is a brand that produces dinnerware and glassware. It was introduced in the United States in the early 1970s and quickly became famous thanks to its durability and convenience.
Corelle is made from a unique glass material called Vitrelle. This material was initially developed for use in the aerospace industry because of its strength and lightweight nature. Corelle adapted this material for use in dinnerware, and the result is a virtually unbreakable product. I have often dropped my Corelle dishes, which have yet to break or chip.
In terms of design, Corelle offers a wide range of patterns and colors to choose from. Whether you prefer a classic white set or something more colorful and modern, there is a Corelle design to suit your taste. The designs are also printed directly onto the glass, so they won’t fade or wear off over time.
What is Corelle Made Of?
Corelle dinnerware is made of a unique three-layer glass laminate called Vitrelle glass. This material was developed by Corning Glass Works (now Corning Incorporated) in the 1940s for use in early television screens. Vitrelle glass is made by fusing three layers of glass.
The process involves heating a sheet of glass until it becomes molten, then cooling it quickly to create the three layers. The three layers of Vitrelle glass used in Corelle dinnerware are:
- The core layer is made from a special type of tempered glass that is strong and durable. It is the layer that gives Corelle its strength and chip resistance.
- The top layer is a protective coating that helps prevent scratches and chips.
- The bottom layer is a protective coating that helps prevent scratches and chips and provides a smooth surface for the dinnerware to rest on.
In addition to Vitrelle glass, Corelle produces glassware made from tempered glass. Tempered glass is heated to a high temperature and then rapidly cooled, making it much stronger than regular glass. This makes Corelle glassware resistant to both thermal shock and impact.
Is Corelle Microwave Safe?
According to the manufacturer, Corelle dinnerware can safely withstand heat up to 350°F, making them microwave-safe. However, using the right dish size is important, and never microwave an empty plate or bowl.
Corelle with plastic lids should loosen the caps to allow steam to escape, and dishes should never be heated under the broiler. While Corelle dishes are sturdy and microwave-safe, they should be treated carefully to prevent breakage.
Are All Corelle Products Microwave Safe?
There can be some confusion when using Corelle products in the microwave. Corelle dinnerware is microwave safe and can withstand heat up to 350°F.
However, it’s important to note that not all Corelle products are microwave safe. Some older patterns may not be able to handle the high temperatures of a microwave. It’s always best to check the bottom of the dish for any warnings before putting it in the microwave.
Can You Put Corelle Mugs In the Microwave?
Corelle mugs are made of stoneware and can be safely used in the microwave. However, it is essential to note that the bottom of the mugs may be rough and can scratch the microwave’s surface. Therefore, placing the mugs on a mat or tablecloth is recommended to avoid scratching.
Additionally, do not overheat the mugs in the microwave, and use oven mitts to handle the hot mugs, as they can become extremely hot. Always allow the mugs to cool slowly and naturally to prevent any accidents.
Can Corelle Go From Refrigerator To Microwave?
Corelle dishes can go from the refrigerator to the microwave. The dishes are made from a tempered glass called Vitrelle, which can withstand high temperatures. This means they are safe to put into the microwave directly after being taken out of the refrigerator.
However, it is essential to note that extreme temperature changes can sometimes cause dishes to break, so it is always best to let the dish come to room temperature before putting it in the microwave. Following these simple guidelines, you can safely and easily microwave your Corelle dishes straight from the refrigerator.

Is Vintage Corelle Microwave-Safe?
Vintage Corelle dishes may not be microwave-safe. Some vintage Corelle patterns have been found to have high lead content in their paints, which can leach into food and pose a health risk if the paint chips or cracks.
Therefore, it is recommended that vintage Corelle dishes be used for display purposes only and not for eating or reheating food in the microwave. It is important to use the right dish size, not microwave an empty Corelle, and not heat or warm Corelle dishes under the broiler part of the microwave oven to avoid any damage or breakage.
Are Corelle Dishes Dishwasher Safe After Being Microwaved?
According to the Corelle brand, their dishwasher is safe after being microwaved. Corelle dishes are made from tempered glass ceramic, sturdy and durable enough to withstand high temperatures without warping or melting.
While microwaving your Corelle dishes, it is imperative to follow some guidelines to ensure safe usage. One of these guidelines is to use a low-power setting and heat the dish for a shorter time than other dishware.
After using them in the microwave, allowing them to cool before washing them in the dishwasher is advisable. Corelle dishes are dishwasher safe, but it is essential to avoid stacking them to prevent damage to their prints and designs.
What Precautions Should I Take When Using Corelle In The Microwave?
Corelle is known for its durability and versatility, it is important to keep in mind that certain precautions should be taken when using it in the microwave.
- Check for microwave compatibility: Before using Corelle in the microwave, ensure the dish is microwave-safe. Most Corelle dishes are, but it’s always good to double-check. You can usually find this information on the bottom of the dish or the packaging.
- Don’t overheat: While Corelle is known for being durable and resistant to chips and cracks, it can break. Avoid using the microwave on high power settings or for extended periods, as this can cause the dish to become too hot and possibly crack or shatter.
- Use a microwave-safe cover: When reheating food in Corelle dishes in the microwave, it’s a good idea to use a microwave-safe cover to prevent splatters and spills. This can help keep your microwave clean and prevent any potential damage to the dish.
- Let it cool down: Once you’ve finished heating your food in the microwave, it’s important to let the dish cool down before handling it. Corelle dishes can retain heat for a while, so be patient and give it a few minutes to cool off before removing it from the microwave.
- Avoid sudden temperature changes: While Corelle is known for being resistant to thermal shock, it’s still a good idea to avoid sudden temperature changes whenever possible. For example, don’t take a dish straight from the freezer and put it directly into the microwave, as this can cause it to crack.
What Makes Corelle Dishes Lightweight And Safe To Use In The Microwave?
Corelle dishes are made of a unique three-layer glass laminate called Vitrelle, originally developed for American military tanks during World War II. Vitrelle is made by fusing three layers of glass – a core layer that gives the dish strength and durability and two outer layers that provide a smooth finish and protect against chips and scratches.
The result is a material that is lightweight yet incredibly strong and resilient. Corelle dishes are three times stronger than traditional ceramic dishes, and they are designed to withstand the rigors of everyday use, including being dropped, bumped, and knocked around. Plus, because they are made of glass, they don’t absorb odors or stains, which makes them easy to clean and maintain.
But what about using them in the microwave? Well, here’s where things get interesting. Because Vitrelle is a type of glass, it is completely microwave safe. Unlike some plastics or other materials that may melt or warp in the microwave, Corelle dishes won’t deform or release harmful chemicals when exposed to high temperatures.
Corelle dishes are not only safe to use in the microwave, but they are also designed to be stackable and space-saving, which makes them perfect for small kitchens or busy households. And because they are so lightweight, they are easy to handle and transport, whether serving dinner at the table or taking leftovers to work.
FAQs About Is Corelle Microwave Safe
Does Using Corelle In The Microwave Affect The Quality Or Durability Of The Product?
Using Corelle in the microwave does not affect the quality or durability of the product. Corelle dishware is made from a material called Vitrelle which is a tempered glass product. This material is designed to withstand high temperatures, making it ideal for use in the microwave.
The heat-resistant properties of Corelle dishware make it safe for serving and reheating food in the microwave. In addition to being microwave-safe, Corelle dishes are chip-resistant and durable, ensuring they can withstand everyday wear and tear.
As long as Corelle dishes are used within the recommended temperature range and handled carefully, they will maintain their quality and durability in the microwave.
Is Corelle Toxic?
Corelle, a popular dinnerware brand, has come under scrutiny due to concerns about high lead levels in pre-2005 pieces.
The New Hampshire Department of Health and Human Services issued a warning on Facebook advising anyone with pre-2005 Corelle dinnerware to consider removing it from their kitchen cabinets and using it only as decorative pieces.
While Corelle assures customers that its products meet safety standards and are routinely tested for lead and cadmium content at third-party laboratories, vintage and legacy pieces produced before tighter lead content safety regulations may contain small amounts of lead, which can be ingested if the paint deteriorates over time.
It remains unclear whether pre-2000 Corelle products comply with today’s safety standards and are safe to use as everyday dinnerware. Therefore, consumers should exercise caution and consider their options carefully, especially if young children or pregnant women are at risk of exposure.
Conclusion
The material component, Vitrelle, is heat-resistant and break-and-chip-resistant, which makes Corelle microwave safe. However, individuals should use a small dish for a small amount of food when microwaving and avoid heating empty dishware to prevent dishes from absorbing too much heat.
It is important to note that vintage Corelle dishes produced before 2005 are not safe for use due to the high level of lead hazard, but Corelle dishes produced after 2005 comply with FDA regulations and are lead-free.
Therefore, Corelle dishes are a safe and convenient option for serving and reheating dishes in the microwave oven. Do you have any questions about is Corelle microwave safe? Let us know in the comments below.
