Hey there, coffee lovers! We all adore a steaming cup of coffee, but have you ever wondered if your coffee mug can go in the oven? Is it safe to do so, or will it crack or break due to thermal shock (a sudden temperature change)? Letâs explore!
Which Coffee Mugs Are Oven-Safe?
The oven-safety of your coffee mug all comes down to the materials itâs made of. So letâs take a closer look at some common materials and whether they can handle the heat:

Material | Oven-Safe? | Notes |
---|---|---|
Porcelain | Rarely | Check for manufacturerâs label or guidelines. |
Stoneware | Yes | Avoid thermal shock by using room temperature mugs. |
Metal | Yes | Be cautious with metal mugs that have plastic parts. |
Ceramic | Usually | Check for an âoven-safeâ label and avoid thermal shock. |
Enamel | Usually | Avoid very high temperatures; not microwave-safe. |
Glass | Usually | Check manufacturerâs instructions; beware of thermal shock. |
Melamine/Plastic | No | Not safe for the oven or microwave; can melt at high temperatures. |
Safety Tips for Using Mugs in the Oven:
- Always check the manufacturerâs guidelines to confirm if a mug is oven-safe.
- Avoid putting cold mugs directly into the oven to prevent thermal shock.
- Use oven mitts to handle hot mugs after removing them from the oven.
- Let mugs cool down gradually to avoid sudden temperature changes.
How Long Should You Put A Mug In The Oven?
