• After the enamel becomes cracked, the only way to use it is to remove the rest of the enamel, and use it as a non-enamelled pot.

Lodge

"We do not recommend preheating an empty piece of enameled cast iron on the stovetop as it could damage the enamel coating. … It is perfectly safe to preheat empty enameled cast iron in the oven since the heat will be more consistently distributed across the entire cooking vessel."

Le Creuset

"Putting a hot pan directly in cold water after being used could spell a recipe for disaster, with thermal shock occurring and causing the cracking or loss of the enamel."

"Just be sure to avoid drastic changes in temperatures which could crack the enamel."
