Glass stovetop kettles can be safe to use if they are used and handled correctly. However, there are a few factors to consider when using a glass stovetop kettle.
1. Quality of the glass: It is important to ensure that the glass used in the kettle is of high quality and can withstand high heat. Low-quality glass may crack or shatter when exposed to sudden temperature changes.
2. Heat source compatibility: Glass stovetop kettles are designed to be used on gas or electric stoves. However, they may not be suitable for induction cooktops, as the magnetic field generated by induction cooking can sometimes cause the glass to break.
3. Proper handling: When using a glass stovetop kettle, it is essential to handle it carefully to prevent accidents. Avoid exposing the kettle to sudden temperature changes, such as placing a hot kettle on a cold surface or adding cold water to a hot kettle. Always use oven mitts or pot holders when handling the kettle to avoid burns.
4. Cleaning and maintenance: Regularly clean the glass stovetop kettle to keep it in good condition. Avoid using abrasive cleaners or brushes that may scratch or damage the glass. It's also important to check the kettle for any cracks or chips before use and replace it if necessary.
5. Water level and boiling time: Only fill the kettle with the recommended amount of water to avoid overfilling. Overfilling may cause the hot water to spill out when boiling, increasing the risk of accidents. Also, be mindful of the boiling time to prevent the kettle from running dry, which can lead to the glass overheating and potentially breaking.
