We've all been there – standing in front of the microwave, food in hand, wondering if the container we're about to use is safe. From reheating leftovers to warming plates for dinner, it's important to know which materials can safely go in your microwave.
Let's clear up some common questions about microwave-safe materials.
Understanding microwave-safe symbols
Before we dive into specific materials, it's worth checking for the microwave-safe symbol on your containers. This usually looks like a small microwave with wavy lines. If you can't find this symbol, it's best to transfer your food to a container you know is safe.
Common materials and their microwave safety
Here are some common materials you’ll encounter, with information on their suitability for the microwave.
Can you put plastic in the microwave?
Not all plastics are microwave-safe. Look for containers specifically marked as microwave-safe – these have been tested to ensure they won't melt or release harmful chemicals when heated. If in doubt, transfer your food to a glass or ceramic container instead.
Never use single-use plastic containers, such as takeaway boxes or margarine tubs, as these aren't designed to withstand microwave heat and could melt or release chemicals into your food.
Can you put cardboard in the microwave?
Plain cardboard, like pizza boxes, can generally go in the microwave for very short periods. However, avoid any cardboard with metal edges, staples, or decorative prints, as these could cause sparking or release harmful chemicals. For safety and better results, it's best to transfer food to a proper microwave-safe dish.
Can you put foil in the microwave?
This is where things get a bit tricky. While modern microwaves can handle small amounts of foil, it's generally safer to avoid it. If you must use foil, follow these guidelines:
- Use small, smooth pieces only
- Never let it touch the microwave walls
- Ensure it's smoothed flat (no crinkles)
- Keep the time in the microwave to an absolute minimum
While technically possible in small amounts, it's better to avoid using any kind of metal foil in your microwave. The risk of sparking and potential damage to your appliance isn't worth the risk.
Can you put paper plates in the microwave?
Plain, unprinted paper plates are generally safe for brief heating. However, avoid any plates with patterns or designs, as these may contain dyes that could leach into your food. For regular use, invest in proper microwave-safe dishes instead.
Can you warm plates in a microwave?
Yes, you can warm ceramic or glass plates in the microwave, but do so carefully. Make sure they're microwave-safe (look for the symbol or check the manufacturer's guidance), and only heat them for 30 seconds at a time to prevent overheating.
Can you put a glass cup in the microwave?
Most glass cups and containers are microwave-safe, but there are exceptions. Avoid using:
- Very thin glass
- Glass with metallic trim or decorations
- Crystal glass
- Glass that's been damaged or chipped
Always check for the microwave-safe symbol, and if in doubt, use a different container.
Safe alternatives for microwave cooking
The safest materials for microwave use are:
- Ceramic dishes (without metallic decoration)
- Glass containers marked as microwave-safe
- Microwave-safe plastic containers
- Purpose-made microwave cookware
Signs that a container isn't microwave-safe
Watch out for these warning signs when heating containers:
- Warping or melting
- Unusual smells
- Containers that become very hot while the food remains cool
- Sparking or crackling sounds
Remember, when in doubt about whether a material is microwave-safe, it's better to use a different container. Your safety, and your microwave's longevity, are worth the extra effort of transferring food to a suitable container.
