It’ll start to harden after 3 to 4 minutes, so you need to work fast.

What temperature does ceramic crack?

Even some oven-safe ceramics can only handle a certain heat level, which poses the question “at what temperature does ceramic crack?” While many ceramics can handle temperatures up to 3,000 degrees F, they can be sensitive to a quick change in temperature.

How do you fix a hairline crack in bone china?
