The Science Behind Anyday Cookware
Understanding the materials, safety, and health benefits of microwave cooking with Anyday. Let's debunk myths and explore the evidence-based science that makes our cookware revolutionary.
Is Metal in Microwave Safe?
The truth about stainless steel in Anyday cookware and why it's perfectly safe for microwave use
Dangerous: Sharp Metal Objects
Forks, aluminum foil edges, and crinkled metal create "arcing" (sparks) because sharp points concentrate electromagnetic energy
- ✗Aluminum foil with sharp edges or wrinkles
- ✗Forks, knives, or utensils with pointed ends
- ✗Metal twist ties or staples
Safe: Smooth Metal Rims
Anyday's stainless steel rim is smooth and rounded with no sharp edges, preventing energy concentration and arcing
- ✓Smooth, rounded stainless steel rim design
- ✓Tested and certified for microwave safety
- ✓No sharp points or edges to concentrate energy
The Engineering Explanation
Microwaves work by emitting electromagnetic waves that cause water molecules in food to vibrate, generating heat. When these waves encounter metal, they reflect off the surface. This is actually why the inside of your microwave is metal—it reflects waves back into the food.
The problem occurs with sharp edges: Sharp points or crinkled metal concentrate electromagnetic energy at those points, causing electrons to accumulate. When enough electrons build up, they discharge as sparks (arcing), which can damage your microwave.
Why Anyday is safe: Our stainless steel rim is intentionally designed with smooth, rounded edges. The curved surface distributes electromagnetic energy evenly without concentration points. Additionally, the rim is positioned at the top edge of the dish, away from the food and microwave walls, minimizing any potential interaction.
This design has been extensively tested and certified by independent safety laboratories. In 2026, Anyday cookware continues to meet and exceed all microwave safety standards set by regulatory bodies worldwide.

Borosilicate Glass vs. Regular Glass
Understanding the superior material science behind Anyday cookware
Soda-Lime Glass
Standard glass used in most cookware
- •Lower thermal resistance: Can crack from sudden temperature changes (thermal shock)
- •Temperature range: Safe from -40°F to 350°F
- •Composition: 70% silica, 15% sodium oxide, 9% calcium oxide
- •Cost: Lower manufacturing cost
Borosilicate Glass
Used in Anyday Cookware
- Superior thermal resistance: Withstands extreme temperature changes without cracking
- Temperature range: Safe from -40°F to 560°F
- Composition: 81% silica, 13% boron trioxide, lower thermal expansion
- Durability: Laboratory-grade material used in scientific equipment
What is Thermal Shock Resistance?
Thermal shock occurs when glass experiences a rapid temperature change, causing different parts of the material to expand or contract at different rates. This stress can cause regular glass to crack or shatter.
Example scenario: Imagine taking a frozen glass dish from your freezer and immediately placing it in a hot oven. Regular soda-lime glass would likely crack from this 400°F+ temperature swing. Borosilicate glass handles this transition seamlessly.
Freezer → Microwave
Take frozen ingredients directly to microwave without defrosting
Microwave → Fridge
Store hot leftovers immediately after cooking with no waiting
Dishwasher Safe
Withstands high-temperature dishwasher cycles without damage
Additional Benefits of Borosilicate Glass

How Microwave Cooking Works
The physics behind faster, healthier cooking with Anyday
Electromagnetic Waves
Microwaves emit electromagnetic waves at 2.45 GHz frequency, targeting water molecules in food
Molecular Vibration
Water molecules vibrate rapidly (billions of times per second), generating friction and heat from within the food
Even Heat Distribution
Anyday's sealed design traps steam, creating consistent temperature throughout the dish for perfect results
Why Anyday Cooks Better Than Regular Microwave Dishes
Silicone Rim Creates Perfect Seal
The platinum silicone rim creates a gentle seal that traps steam inside, preventing moisture loss while allowing pressure to escape safely through the vent system. This means your food stays moist and tender, not dried out like with open containers.
Intelligent Venting System
The stainless steel knob has two positions: lift to vent steam during cooking (preventing pressure buildup), or push down to seal for storage. This two-way system is unique to Anyday and prevents messy explosions while ensuring even cooking.
Optimal Glass Thickness
Anyday's borosilicate glass is engineered to the perfect 3.5mm thickness—thick enough to retain heat for even cooking, but thin enough to allow microwaves to penetrate efficiently. This balanced design cooks food 30% faster than thicker ceramic dishes.
Frequently Asked Questions
Common questions about microwave cooking safety and Anyday materials
Does microwave cooking destroy nutrients?
No, this is a myth. Scientific studies show that microwave cooking actually preserves more nutrients than boiling, steaming, or frying. As shown in our nutrient retention data above, microwaving vegetables retains 10-25% more vitamins compared to boiling. The key factors are shorter cooking times and minimal water usage, which prevent nutrient loss.
Is it safe to put metal in the microwave with Anyday?
Yes, Anyday's stainless steel rim and knob are specifically designed for microwave safety. The smooth, rounded edges prevent arcing (sparks) that occur with sharp metal objects. Our design has been extensively tested and certified by independent safety laboratories. However, never place other metal objects like forks, aluminum foil, or twist ties in the microwave.
Can I use Anyday in a conventional oven?
Yes! Anyday cookware is oven-safe up to 560°F (293°C) when you remove the silicone lid. The borosilicate glass can handle high temperatures without cracking. This makes Anyday incredibly versatile—use it in the microwave, oven, freezer, and dishwasher. Just remember to remove the silicone components before placing in the oven.
What makes borosilicate glass better than regular glass?
Borosilicate glass has superior thermal shock resistance, meaning it can withstand extreme temperature changes (freezer to microwave, or hot oven to cold counter) without cracking. It's made with boron trioxide, which gives it a lower coefficient of thermal expansion compared to regular soda-lime glass. This is the same laboratory-grade material used in scientific equipment and premium cookware worldwide. It's also more resistant to scratches, stains, and chemical corrosion.
Do microwaves cause cancer or radiation exposure?
No. Microwaves use non-ionizing radiation (like radio waves), which is completely different from ionizing radiation (like X-rays) that can damage DNA. The electromagnetic waves used in microwave ovens simply cause water molecules to vibrate and generate heat—they don't make food radioactive or change its molecular structure. The FDA, WHO, and all major health organizations confirm that microwave cooking is safe. The metal walls of your microwave contain the waves inside, and modern microwaves have safety interlocks that stop operation when the door opens.
Why does the lid sometimes feel stuck after microwaving?
This is due to vacuum seal effect. When you cook food, steam builds up inside the dish. When it cools, the steam condenses back into water, creating a slight vacuum that "sucks" the lid down. This is actually a sign that Anyday's seal is working perfectly! To release: simply lift the knob to break the seal and allow air in. You can also run warm water around the rim to equalize the pressure. This vacuum seal is what keeps leftovers fresh longer in the fridge.
Can I freeze food in Anyday dishes?
Anyday cookware is freezer-safe down to -40°F (-40°C). You can prep meals, freeze them in Anyday, then cook directly from frozen in the microwave—no need to transfer to another container or wait for defrosting. This is where borosilicate glass really shines, as it handles the extreme temperature change from freezer to microwave without any risk of cracking. Just remember to leave some space at the top for food expansion when freezing liquids.
Is Anyday dishwasher safe? How should I clean burnt food?
Yes, all Anyday components (glass, lid, and silicone rim) are dishwasher safe on the top rack. The borosilicate glass withstands high-temperature dishwasher cycles without clouding or degrading. For burnt or stuck-on food:
- • Fill dish with warm water and a drop of dish soap, microwave for 2-3 minutes. The steam will loosen debris.
- • For stubborn stains, make a paste of baking soda and water, let sit for 15 minutes, then scrub.
- • The non-porous glass surface won't absorb stains, making cleaning easier than plastic.
What is the platinum silicone, and why is it better?
Anyday uses platinum-cured silicone, which is the highest grade available. Unlike peroxide-cured silicone (used in cheaper products), platinum silicone doesn't contain fillers or release volatile compounds when heated. It's FDA-approved for food contact, BPA-free, and can withstand temperatures from -40°F to 500°F without degrading. This medical/food-grade material is odor-resistant, non-toxic, and maintains its flexibility and seal integrity even after years of daily use. It's the same silicone used in baby bottle nipples and surgical implants.
How long will Anyday cookware last compared to plastic containers?
Anyday cookware is designed to last decades with proper care. Borosilicate glass doesn't degrade, scratch, cloud, or absorb odors like plastic. The platinum silicone maintains its seal and flexibility for years. In contrast, plastic containers typically show wear (staining, warping, cracking) within 1-3 years, especially when microwaved regularly. Many Anyday customers report their dishes still look brand new after 3+ years of daily use. This longevity makes Anyday more economical and environmentally friendly than replacing disposable plastic containers every few years.
