How do you know whether your kitchenware can be used in microwave?

To determine whether your kitchenware can be safely used in the microwave, you should look for information on the packaging or manufacturer's website. Here are a few tips to help you determine whether your kitchenware is safe for use in the microwave:
Look for microwave-safe labeling: Check the packaging or product label for any specific instructions related to microwave use. Most kitchenware products that are safe to use in the microwave will have a "microwave safe" label or logo.
Check the material: Kitchenware made of glass, ceramic, and microwave-safe plastics are typically safe to use in the microwave. Metal or metallic accents on dishes, as well as aluminum foil or metal cookware, should never be used in the microwave as they can cause a fire or damage the appliance.
Conduct a test: If you're unsure whether a particular kitchenware item is safe for use in the microwave, you can conduct a simple test. Place the item in the microwave with a cup of water and heat for 30 seconds. If the item stays cool and the water gets hot, it's likely safe to use in the microwave.
Contact the manufacturer: If you can't find information on the packaging or label, contact the manufacturer directly for guidance on whether their product is safe to use in the microwave.
