❗Can you put a glass plate in the oven ?-pureglassware

Whether a glass dish can be placed in a microwave oven depends on its material and characteristics. Heat-resistant glass (e.g. borosilicate glass) is usually safe to use, while ordinary glass may break due to uneven exposure to heat and cold. Here are key considerations: 

1️⃣ . Verify that it is “microwave safe”

- Check for the “Microwave-safe” symbol on the bottom of the dish.

- Check the bottom of the dish for the “Microwave-safe” sign. Check that the glass dish is not overused and is not cracked.

2️⃣ . Avoid sudden temperature changes

- Do not put the glass dish which has been frozen in the refrigerator directly into the high temperature microwave oven, in order to prevent it from blowing up due to rapid cooling and heating.

- Place a rag on the bottom of the plate when removing it after heating.

3️⃣ . Pay attention to metal decorations and cracks on plates

- Sparks may be generated by the gold threads on the mouth of the dish or the metal decorations on the body of the dish, which may cause a hazard.

- Cracked or worn glass dishes are fragile and are not recommended.

4️⃣ . Alternatives 

If you are unable to confirm the suitability of the glass plate itself, you may replace it with another material:

- Ceramic dishes (without metal decoration).

- Plastic labeled “microwave safe”.

⭕ Summary 

Heat-resistant glass dishes are microwave safe, but care should be taken to avoid rapid cooling and heating, metal decorations, and the degree of use of the dish itself. If you are unsure, it is advisable to choose dishes that are clearly labeled as microwave safe to ensure safety!
