What materials are GlassLock products made of?

Asked 4 months ago
GlassLock products are made primarily from high-quality glass, which is designed to be both durable and safe for storing food. The glass used in these containers is often borosilicate glass, a type that is known for its strength and resistance to thermal shock. This means that it can withstand sudden changes in temperature without cracking, making it suitable for use in both the freezer and oven, as well as for reheating in the microwave. In addition to the glass component, many GlassLock containers feature airtight and leak-proof lids, which are typically made from high-grade plastic materials. These lids often include a silicone sealing mechanism, ensuring freshness and preventing spills. It is important to check the specifications for particular products, as some lids may vary slightly in their composition. GlassLock products are designed to be safe for use in various settings, emphasizing both functionality and user safety.
