Have you ever wondered which types of glass tableware are safe to use in the microwave? Or how to tell if your glassware is truly safe for food use? Many people aren’t aware of the differences between various glass products, and that can lead to unexpected accidents. For instance, some glass items can shatter suddenly when exposed to heat or temperature changes, posing serious safety risks. That’s why it’s important to understand the materials used in your glassware and follow the manufacturer’s guidelines to ensure safe usage.
According to experts from Lock & Lock, the material used in glassware plays a crucial role in determining its safety and durability. There are generally three main types of glass used in kitchenware: regular glass, tempered glass, and heat-resistant glass. Regular glass is delicate and not suitable for high temperatures. Tempered glass, often found in car windows and shower doors, is stronger but still vulnerable to sudden temperature changes, making it less ideal for use in hot kitchens. On the other hand, heat-resistant glass is designed to withstand extreme temperature fluctuations without breaking. It also doesn’t release harmful chemicals when heated, making it a safer choice for everyday use.
The heat-resistant glass used in Lock & Lock products contains boron, which gives it excellent thermal stability. This means it can handle both very hot and very cold conditions without cracking or breaking, even when exposed to “ice and fire†temperature differences. As a result, it offers a higher level of safety and reliability for cooking and serving food. Whether you're heating up leftovers or pouring a hot drink, choosing the right type of glassware can make a big difference in your kitchen experience.
