Many people think that putting a coffee mug in the oven is unsafe and prone to fire problems, or at worst, the cup will crack when taken out of the range. So can coffee mugs go in the oven?
Yes, the answer is absolute, but not every mug can be put in the oven. And How do you know if a mug is oven-safe? We will reply to you.
First, you need to know the features of the mug; the manufacturer often announces this information on the product packaging or in the advertisement. However, suppose you have a favorite mug on the shelf for years and decide to use it to store your coffee in the oven. In that case, you can check its safety by preventing the material of the mug and seeing the manufacturer’s recommendations on the bottom of the mug.
Some Common Materials To Help You Determine If Your Mug Is Oven Safe:
– Terracotta, ceramics
This is the material commonly used to make coffee mugs. Coffee mugs made of terracotta will be painted with a layer of color and are very susceptible to chipping. This material is vulnerable to heat, causing structural expansion, so earthenware coffee cups are not safe to use in the oven.
However, ceramic coffee cups have a more diverse classification with heat resistance levels, unlike terracotta. The ceramic coffee mug fired at high temperatures will withstand the heat in the ovens without cracking.
If you cannot determine whether your coffee cup is terracotta or ceramic, you should not put it in the oven because there will be high risk.
– Stone material
Cups or bowls dishes made of Stone are highly heat resistant and safe to put in the oven. Cups or utensils made of Stone will be thick and opaque with a baked glaze on the inside. Besides, its outer surface texture will be rough.
– Porcelain material
Some porcelain materials such as plates and bowls are safe to put in the oven; however, with porcelain coffee mugs, this is not possible. Because porcelain coffee cups are difficult to glaze uniformly, they are often thin and susceptible to thermal shock. However, you can rest assured when putting the ceramic coffee cup in the microwave or dishwasher.
– Chinese material:
Coffee cups made of clay from China are often sophisticated and beautiful. However, you should never put them in the oven or dishwasher. These coffee cups are thin and intricately designed, so they can easily damage when placed in the oven.
– Metal material
If designed in a 100% metal monolithic style, metal coffee cups are safe to put in the oven. However, if your cup has plastic elements inside, it is easy to be damaged because the plastic meets high temperatures and will melt.
– Plastic or acrylic material
All materials made of plastic or acrylic will melt in the oven; this is not the case with coffee cups.
– Glass material
Previously, materials made of glass would not be placed in the oven. However, the technology of making glass has changed; some types have been designed to withstand the high temperatures inside the oven. Therefore, if you want to use a glass beaker to put in the oven, you should carefully consider the recommendations from the manufacturer.
If you don’t know what material your mug is made of, you can read what’s printed on it or see the box outside the cup. Some sets of cups will come with instructions on the side of the box.
How Long Do You Put A Mug In The Oven?
Different types of cups have other oven-safe times. There are cups with materials that won’t be put in the oven, but cups can be used without damage. The highest heat resistance is next to products made of Stone. If you want to know if your cup can be put in the oven, you can look at the information on its shell. Materials that should not be placed in the oven are porcelain, pottery, and earthenware cups.
Coffee mugs come in many different types with different materials and decorations. Typically, cups are not set to temperatures above 100 degrees Celsius. However, the cup industry has increased the quality of cups by producing cups that are both more heat-resistant and still meet users’ needs. This increases competition in the market.
When you put the cup in the oven, high temperatures will affect your cup and quickly explode when exposed to steam. Therefore, materials that are not heat resistant are prone to cracking, melting, and exploding when exposed to moisture—especially those made of terracotta, glass, or plastic. But with suitable quality cups, if the manufacturing process is poor, it will still end.
With ceramic cups, depending on the temperature when the manufacturer heats them, the higher the temperature, the more heat-resistant the cup will be when in the oven. With enameled cups, the water absorption during boiling is higher than usual. Therefore, you should not put them in the oven.
The maximum time you can leave the cup in the oven is no more than half an hour. To avoid damage to the cup due to thermal shock, before you start to roast your coffee, you should preheat your cup at a high temperature for 15-30 minutes, depending on your needs. In particular, please pay attention to placing the cup in the oven before heating and only taking it out after it has stabilized.
The ideal temperature you should set for a cup of coffee is 140 degrees F. When you take the coffee cup out of the oven; the cup will gradually cool down and return to its normal steady state.
In addition, you should not put the mug in the oven at too high a temperature; the temperature only between 185F and 200F is best. It’s up to you how you roast your coffee to set the temperature, as too much heat will cause the cup to crack and cause the coffee inside to burn.
