Why did my glass lid shatter?
Our glass lids are made of tempered glass, which is an extremely durable and safe material. That said, there is a common misconception that tempered glass lids are "unbreakable."
There are a few ways that tempered glass lids can become damaged. Over time, small scratches caused by cleaning the lid with a scouring pad or harsh abrasives, or other nicks caused by utensils and cooking, can weaken the tempered glass. These scratches can lead to spontaneous or delayed breakage, in which the lid appears to explode or implode for no apparent reason. Extreme temperature change, such as running a hot lid under cold water, can also result in glass lid breakage.
We use tempered glass lids for our products not because it is indestructible, but because it breaks more safely than ordinary glass. Tempered glass is designed to fracture into small, relatively harmless pieces when broken, as opposed to the jagged shards that ordinary glass may break into.
