Safety tips: Things to know before microwaving CorningWare

Though CorningWare products are microwavable, there are some tips one must remember to ensure the safety of the food, oven, and longevity of the product.

We have already warned people to maintain a low to medium temperature. Apart from that, there are a few other safety tips too. 

Before you put CorningWare in the microwave, make sure you go through the following safety tips mentioned below:

Examine the container properly

Before putting any CorningWare in the microwave, flip your dish to see its bottom. Now check what’s written on it. Some dishes are labeled as microwave-safe while some are labeled as not microwave-safe. You must confirm that the dish is microwavable before putting it inside the oven.

Don’t fill the container to the brim

If you intend to warm water, you must fill the CorningWare container halfway. Take one liter of water in a bottle and place it inside the CorningWare dish. Don’t microwave for more than 30 seconds. After you have switched the microwave on, don’t leave the spot and get occupied with other activities.

Restricted Foods

Though it says that CorningWare products can withstand extreme temperature changes, they may crack or fracture sometimes.  That’s why people shouldn’t use CorningWare products to heat prepackaged food items.

One shouldn’t also heat or microwave popcorn in a CorningWare dish. People are advised so because such items contain special browning wrappers that produce too much heat. 

Appliance Restrictions

There are a few models of microwaves that come with an inbuilt browning element, meant to make any food crispier. If you have such a type of microwave, you shouldn’t put CorningWare inside. It can cause breakage or fracture of the product. Therefore, people mustn’t use CorningWare together with a browning feature, irrespective of the type of dish.

At the same time, one should avoid heating an empty or partially filled CorningWare dish.  Fill it with enough food and then heat it.

Proper maintenance

While you are using Corning ware, you must take good care of it. After cleaning the CorningWare dishes with water, don’t let the water soak in for a long time. It can reduce the life expectancy of the product. It will also affect the quality of the dish to withstand repeated microwaving.
