Best Practices for Microwaving Porcelain
If you have confirmed that the porcelain is microwave-safe, follow these best practices to ensure safety and preserve the quality of your dinnerware:
Pre-heating Your Porcelain
Before placing porcelain in the microwave, it’s best to pre-heat it:
- Allow the porcelain to sit at room temperature for a bit (especially if it was stored in a cold area like a refrigerator).
- Microwaving porcelain from extreme cold can lead to temperature shock.
Microwave Settings and Time
Using a medium power setting is recommended for porcelain. Consistently microwave in shorter intervals to gradually heat the item rather than shocking it with intense heat.
Testing for Safe Use
When microwaving a new porcelain item, it’s best to test its safety. Follow these steps:
- Microwave the item for 30 seconds with a glass of water alongside it. If the porcelain remains cool, it is likely safe.
- If it becomes too hot while the water is still cool, refrain from microwaving that platter or bowl in the future.
Alternatives to Microwaving Porcelain
If you want to avoid any potential risks, consider alternatives for warming your food:
