what makes some glass containers super heat proof and others crack under heat?
In: 5
It’s called borosilicate glass.
They are two materials – Boron and Silicon to the glass
When you heat things up, they get slightly bigger. When they cool down, they get smaller.
Regular glass expands a lot with heat. If one side of the container heats up and expands while the other side is cold – then it cracks.
But borosilicate glass expands less, so it’s tolerant of bigger changes.
Sometimes heating up a cold dish cracks it.
Sometimes cooling down a warm dish cracks it. Often glass will break when you wash it in the sink because the cold water suddenly cools it down.
