Square Jars

Square jars with wide mouths are perfect for jams, jellies, and other preserves, and as such you could use either a round or a square jar.

Square jars are great for storing dry goods like rice, beans, and pasta. No matter what your needs are, there's sure to be a glass jar that's perfect for preserving food, bottling your homemade goods, and storing pastas, rice, sugar and more.

Square jars are great for storing dry goods like flour, sugar, and rice
If you're looking for a more efficient way to store your dry goods, then you should definitely consider switching to square jars. There are many benefits to storing dry goods like flour, sugar, and rice in square jars.

Square jars take up less space than round jars. The increase in storage between square and round is roughly 25%. Square jars are also easier to stack, so you can make the most of limited storage space. Not to mention, they look a lot nicer on shelves and in pantries.

Round jars are perfect for canning fruits and vegetables
For anyone who loves to cook, canning fruits and vegetables is a great way to preserve the harvest and enjoy seasonal flavours all year round. And while there are many different types of jars, the best ones to use for canning are our 500ml Mason Jars.
The round shape of these jars makes them perfect for storing food, as the smooth sides of round jars make them easy to clean, ensuring that your food will be free of bacteria and other contaminants.

Round jars are also less likely to break than other types of jars, making them a safer option for canning. So if you're looking for the perfect container for your next canning project, be sure to choose a round Mason jar.

Can Square Cans Really Improve the Utilization of Refrigerator Space?

Square cans are a very practical kitchen tool that provides us with many conveniences and benefits. Whether in family life or in the workplace, using square cans can help us better keep food fresh and effectively manage our refrigerator space.

First of all, using square cans can extend the shelf life of food. Square cans have sealing properties that can prevent food from being contaminated by outside air and bacteria. In this way, the freshness of food can be effectively protected and not easy to deteriorate. Especially for foods that are prone to moisture, such as vegetables and fruits, the use of storage boxes is even more indispensable. Putting vegetables and fruits in storage boxes can minimize the loss of moisture and nutrients, making our diet healthier.

Secondly, square cans can effectively manage refrigerator space. The refrigerator is an important place for us to store food, but unreasonable placement will lead to a waste of space. Using refrigerator square cans can classify food and make the refrigerator well organized. We can classify food according to type, purpose or shelf life as needed, and then put it in the corresponding storage box. In this way, we can clearly see the space occupied by each food, and there will be no situation where the refrigerator is full of food but we can't find what we need. At the same time, square cans can also prevent cross-contamination between foods, making food safer and more hygienic.

Finally, square cans can also help us save time and energy. When we need to take food from the refrigerator, we only need to open the corresponding storage box without searching one by one. This not only saves us time looking for food, but also reduces the loss of cold air in the refrigerator and saves energy. In addition, square cans can also prevent food from splashing and odor from spreading, keeping the refrigerator clean and tidy, and reducing the workload of cleaning the refrigerator.

Can Square Jars be Put in the Microwave?

Although square cans are environmentally friendly packaging with good waste disposal performance, they can protect tea, food, cosmetics, moon cakes, cooking oil and other commodities from natural factors such as sun, wind, rain, dust and contamination, and prevent volatilization, contamination, collision, leakage, melting, extrusion, loss and theft. However, it is necessary to be cautious when heating in a microwave oven. The heating principle of a microwave oven is to use water and food to absorb microwaves and make them heat up to achieve the heating effect. The material of the metal container iron box is tinplate metal. When microwaves encounter the metal iron can container, they will reflect. This will not only prevent the food from absorbing microwaves and heating, but also damage the core components of the microwave oven.

The basic properties of microwaves are usually presented as three characteristics: penetration, reflection and absorption; for glass materials, plastic packaging and porcelain, microwaves almost pass through without absorbing heat. Magnetrons are used in daily household microwave ovens to convert electrical energy into microwave energy. Therefore, when using microwave ovens, we should use easily penetrable glass, plastic and porcelain products. If it is necessary to heat food in iron cans, the food in the iron cans can be poured out and placed in easily penetrable glass, plastic and porcelain products for heating.

1. Before heating square canned food in a microwave oven, open the top cover of the square can completely to prevent all microwaves from being reflected. At the same time, the heating time should not be too long to reduce the probability of damaging the microwave oven.
2. Limit on the number of heated cans: The microwave oven can only heat one iron can at a time;
3. Place the can in the middle of the glass turntable of the microwave oven, and the square can of food packaging must not be less than 2.5 cm away from the walls of the microwave oven. If the microwave oven does not have a glass turntable, the square can of food packaging must be placed on a porcelain plate before heating.

Make sure to Clean your jar Thoroughly Before use to Avoid Bacteria Growth

It's important to make sure the jars are clean before use, especially if you’re storing or preserving food. Bacteria can easily grow in warm, moist environments. If not properly sterilised, the square jars can contaminate the food inside and cause illness.

The good news is that it's easy to sterilise square jars at home. Simply wash the jars in hot, soapy water, then place them in a pot of boiling water for 10 minutes. This will kill any bacteria that may be present and help to ensure that your canned foods stay fresh and safe to eat.

Now that you know all about the different types of square jars and their uses, it's time to get shopping! And remember, always clean your jar thoroughly before use to avoid bacteria growth.
