How-to-Tell-if-a-Mug-is-Oven-Safe

The most significant criteria to consider when asking about the safety of coffee mugs in the oven depends on the quality and manufacturer’s instructions. They can tell you whether or not your cup is oven-safe. So, here I will tell you some vital information based on which you will tell if a mug is oven safe or not. So, let’s see:

Material

  • Plastic: Mugs that are made with plastic is not able to withstand heat. Because any mug constructed of this plastic material will immediately melt when subjected to high temperatures. Your mug won’t be oven safe if any part of it is made with plastic, whether it’s handle or body.
  • Metal: Mugs made with pure metal are oven friendly because this material has excellent heat conductivity. You just need to ensure it’s made of solid metal with no non-stick coatings or plastic sections, as these materials don’t conduct heat properly.
  • Glass: People mistakenly think that glass remains impervious to heat. Several glass types can withstand oven heat due to recent improved technologies. To be assured, look for instructions from the maker.
  • Bone China: Mugs made with bone china are delicate, and don’t even think to put it into the oven. Because they are very thin and frequently have elaborate decorations on the outside and paintings.
  • Porcelain: Another substance that can be used in the oven safely is this one. However, not all porcelain mugs may not be used in the oven. It’s because porcelain is a delicate material with a high thermal shock sensitivity.
  • Stoneware: Stoneware can be used in the oven because it is heat-resistant. Mugs made with stoneware are frequently opaque. They’re also available in various finishes, including gleaming and coarsely baked.
  • Earthenware: Many kitchen items are made with earthenware and have beautiful prints. But because of the possibility of chipping, it is not suitable and safe for oven use.
  • Decorated: Keep in mind that every kitchen equipment with decorations isn’t suitable for using the oven. This is because the factory will apply the decorations just after the mug burning process is completed.

    These decorations make the mugs look nice, but they quickly shatter or break under intense heat.

Manufacturer’s Guidance

Underneath the mugs, you can readily find manufacturers’ guidelines and the material properties. For example, an “oven, stove, & dishwasher-safe” certification is what you’re looking for.

If your mug has no printed or written information on it, then look at the packet. Most of the mugs feature a user guide for maintenance, which is usually in the shape of a little book.

In furthermore, most mugs have a brand emblem on them so you can clearly recognize who made them. As a result, you can check their website to see if your newly purchased mug is safe for oven use or not.

However, avoid mugs with sticky graphics, and even if the cups are glazed, be sure they were made to be used in the oven. If you don’t find any oven safety confirmation in the mug’s body or in the packet, avoid using it in the oven.
