Make sure there are no plastic elements on the cup.
Can i put a ceramic mug in the oven.
A pure metal cup like a camping mug should be safe to put in the oven.
A mug with a plastic handle or grip will have the same problem.
Place the freshly painted mug in a cold oven.
Many people may think that any type of ceramic bowl can be placed in a hot oven.
Turn the oven onto bake at 360.
One final remark needs to be added about coffee mugs made out of thin porcelain.
Most coffee mugs are made from some kind of ceramic.
Yes kelly you can but it will be hotter than blue blazes when you take it out.
Bake for 30 minutes.
However the glaze that is placed onto the ceramic bowl isn t always oven safe.
When the 30 minutes is up turn off the oven but leave the mug inside.
Nonstick finishes will also react poorly to heat.
All plastic cups and mugs will melt if put in the oven.
