First and foremost, durability is one of the most significant features of tempered glass containers. Tempered glass is produced by a process that involves heating the glass to high temperatures and then cooling it rapidly. This treatment enhances the glass's strength, making it more resistant to shattering compared to regular glass. As a result, tempered glass containers can withstand extreme temperatures, whether in the freezer, oven, or microwave. This versatility means you can store leftovers, reheat meals, and even bake directly in the containers without worrying about cracks or breaks. Such durability reduces the need for frequent replacements, ultimately saving money in the long run.
