Microwaving Metal? A Guide to Microwave Safe Steel

We’ve all heard the dire warnings: "Never put metal in the microwave!" But here’s a little-known secret that might just blow your culinary mind: not all metals are microwave no-nos.  Thanks to a specific steel composition and smooth, rounded design, some stainless steel lunchboxes defy the conventional wisdom and make microwaving with metal not only possible but safe. So, how does it all work, and what should you know before you start nuking your leftovers in stainless style? Let's dive in!

How Do I Know Which Stainless Steel Boxes Are Safe?

Be sure to check with the manufacturer. Three of the Elephant Box ranges are microwave safe. The Prep & Store Range, the Lunch Bowls (including the lid) and the Clip & Seal Range have all been tested and are safe for use in the microwave.  

So, How Do These Work in the Microwave?

First things first, let’s address the science behind why these stainless steel boxes don’t turn your microwave into a mini fireworks display. Unlike some metals that can cause sparks and arcs (we’re looking at you, aluminum foil and cheap cutlery), these boxes are crafted from stainless steel with a design that prevents such mishaps. Their smooth, rounded edges help distribute electromagnetic waves evenly, avoiding the sharp edges that can cause sparking.

Rigorous testing and adherence to stringent safety standards ensure that these boxes are microwave-friendly. So, rest assured, you won’t be re-enacting any scenes from a sci-fi disaster movie.

What Do I Need to Know Before Putting These Boxes in the Microwave?

Alright, you’re ready to test the waters (or rather, the waves). But before you start, here are some crucial tips to ensure your microwaving experience is both safe and effective.

1. Compatibility: If your microwave dates back to the Stone Age (okay, maybe just a few decades), specifically older 915 MHz models, these boxes are a no-go. Stick to modern microwaves up to 1000W for best results.

2. Initial Use: Give all parts a good wash with warm, soapy water before the first use.

3. Condition: Avoid using any boxes that have major dents or deep scratches. While the boxes are designed for microwave use, significant damage can compromise their safety.

4. Avoiding Sparking: Remember the cardinal rule of microwave metal management: no cutlery, no foil, no multiple boxes at once. Heat one box at a time to keep things spark-free.

5. Heating Time: Stainless steel takes a bit longer to heat compared to plastic or glass. So, expect slightly longer microwaving times.

6. Contact with Metal: Ensure the box doesn’t touch any metal surfaces inside the microwave, such as metal plates, racks, or the microwave walls. We’re aiming for safe, not shocking.

7. Microwave Power: These boxes are best buddies with microwaves up to 1000W. Anything higher might be a bit too intense.

8. Handling: Post-microwave, the box will be hot. Protect your hands with oven gloves or a tea towel. Safety first, always.

9. Lid Management: The lids (but not the lunch bowl lids) are not microwave-safe. Always remove the lid before microwaving your food - except for the lunch bowl! Just make sure the vacuum tab is up.

Wrapping Up (Without Foil)

Using stainless steel boxes in the microwave might sound like a magic trick, but it’s really just good design and smart science. By following these tips, you can enjoy the convenience of microwaving without the worry.
