Yes, you can can in colored jars! Canning is a preservation process that involves transferring cooked food from the kitchen to an air-tight container, like a jar. While the traditional canning jars are typically clear or light blue, you can use colored jars for canning.
Although the color of the jar won’t affect the food, it can add an decorative element to the canned food. When canning with a colored jar, make sure to purchase a lid with a rubber seal that fits securely in order to ensure a tight seal and prevent spoilage.
You’ll have to sterilize the colored jar, just like any other type of jar, and make sure not to expose the jar to direct sunlight while it’s in the canning process. The best type of colored jars to use are those that are made of heat-resistant glass or those labeled as “heat-safe” jars.
As long as you follow your canning recipe’s instructions, you can successfully can your preserves in beautiful, colored jars.
What kind of jars should not be used for canning?
Generally speaking, any jar that is not specifically intended for canning should not be used for this purpose. Any jars used should be designed for high-temperature processing, contain no cracks or chips, and can maintain a proper seal.
Jars with shoulder-seal lids, such as those used for pickles and olives, should never be used for canning. Additionally, home canners should avoid using jars with tin lids that are not specifically designed for canning, as these do not properly seal.
Mason, Ball, and Kerr jars are all designed for canning, as are many others. Prior to using any canning jars, it is important to thoroughly inspect them for any defects or imperfections that could cause problems during the canning process.
Are all glass jars safe for canning?
No, not all glass jars are safe for canning. Canning requires a specific type of jar – usually a Mason jar – and it is important to use the correct lid for a safe seal. Additionally, all jars should be free from any visible flaws or cracks, and any older jars should be checked for wear and tear.
Jar manufacturers typically designate the types of jars that are suitable for canning, and many guidelines exist for safe canning practices. Certain types of jars, such as mayonnaise, salsa, and jelly jars, are not suitable for canning.
Using a jar that is not specifically designated for canning could result in a broken seal, which would cause the food to spoil before it can be safely consumed.
Can I use supermarket jars for canning?
No, you should not use supermarket jars for canning. Canning jars are specifically designed and tested to be able to withstand the heat and pressure of boiling and canning. Reusing jars designed for single-use can weaken and corrode the jars, leading to breakage and potentially creating a health hazard.
Supermarket jars are not made of the same materials and are not designed to withstand the same high temperatures and pressure. Additionally, supermarket jars may contain chemicals that should not be heated or come into contact with food, posing another risk.
Instead, opt for canning jars specifically designed for this purpose for a safe and successful canning project.
What is the difference between Mason jars and canning jars?
Mason jars and canning jars are actually the same thing. Both terms refer to the type of jar designed with a threaded screw-on lid that creates an airtight seal, making them popular for canning and preserving food.
However, Mason jars are actually a specific brand of canning jar created by the Mason Jar & Bottle Company in the late 1800s. They are usually made of clear glass and feature the company’s namesake raised on the side of the jar.
While Mason jars were originally marketed as a revolutionary home canning solution, they’ve since become a popular choice for decorative uses, such as centerpieces and storage solutions, due to their airtight seal and clear design.
In contrast, canning jars refer generally to the style of jar with a screw lid, including many brands like Ball, Kerr, and Atlas that have become standards in the home canning industry.
What other types of containers can be used for canning?
In addition to traditional canning jars, there are several other types of containers that can be used for canning. Mason jars are the most common option, but plastic freezer containers and plastic storage containers also work.
Additionally, any type of wide-mouthed, rectangular, or cylindrical container that can be sealed or tightly covered is a suitable option. Freezer bags—especially ones made of durable, food-grade plastic—can also be safely used for canning.
Lastly, specialty canning containers, such as metal tins and clay pots, can also be used, although they are not as common or widely available as the other aforementioned containers.
What can I use instead of a Mason jar?
If you are looking for an alternative to a Mason jar, there are a variety of other glass containers that can be used to store and organize items. Popular options include canning jars, canisters, bell jars, jugs, demijohns, stoppers, candy jars, apothecary jars and even wine bottles.
Each offer their own unique look and feel, making them great options for home décor, organization and storage. Additionally, there are many ceramic, plastic, and metal containers that can work similarly to a Mason jar.
These can be found in various sizes, shapes and colors, and many have special features such as lids, handles, and compartments. With all of these options, you should have no trouble finding the perfect alternative for your storage needs.
Why were old canning jars blue?
The blue hue of antique canning jars is a result of an old tool called a “Metal Mold” which was used to produce these jars from the 1870s through the 1910s. The Metal Mold was used to shape the glass and stamps that would be used to create a consistent design in the jars.
This method of glass production often produced translucent blue glass, which would result in the light blue hue that is found on many antique canning jars. This blue coloring was actually also seen on many glass items made during that time period, such as bottles, glasses, and lamps.
The glass was often refered to as “Vaseline” glass because of its light yellow-greenish hue.
The glass producing factories of the time switched to the patented “Owens Automatic Bottle Machine” (patented in 1903), which produced a different style of glass which was completely clear. The old blue tinted glass slowly phased out as this new machine became more popular.
As of today, there are modern reproductions of jars from the “Metal Mold” period available, however, they are not as common since the originals are hard to come by or are too fragile to use.
How do you date old blue mason jars?
Dating old blue mason jars can be a bit tricky, as they don’t have many distinguishing factors that can help with pinpointing an exact year of manufacture. However, there are a few key factors that can help you figure out the approximate age of your jar.
One of the main identifiers of vintage mason jars is the logo. Old Ball jars and Kerr jars typically have logos with the company’s name and location printed on them. The Ball logo, for instance, began using block letters in the mid-1920s, so if you find one of these, it’s likely from that era.
The exact date of the logo change is hard to pinpoint, as it could vary from one region to the next.
The style of the lid is another factor to look at when dating a mason jar. The wire bail system was perfected and widely used in the 1910s and ’20s, and was the standard for 50–75 years. During the 1940s and ’50s, the two-piece lids with the rubber seal were introduced, and were widely used for about 30–50 years.
The mold number or finish on the tops and/or bottoms of the jar can also help to date them. Many Ball jars have a number on the bottom, like 5, 8, or 1. A 5 indicates the jar was made between 1885 and 1887, 8 signifies 1888 to 1910, and 1 stands for 1912 to 1933.
Finally, the color of the jar can also help in dating. Until the 1950s, jars were usually made in shades of opaque glass—aqua, greenish blue, and even black. After that time, jars were made mostly in a clear color, for decorative purposes.
In the end, dating a blue mason jar is all about using the clues you’re able to observe and making an educated guess. If you’re still uncertain, consult a book or website that has a comprehensive list of vintage mason jars and their associated values.
Are blue mason jars rare?
Yes, blue mason jars are relatively rare compared to other colors. During the early 1900s, many mason jars were manufactured in shades of blue, but the popularity of other colors eventually overtook blue.
Over time, the blue mason jars lost their appeal and gradually became harder to come by. Today, blue mason jars are considered rare and highly collectible pieces. While you may be able to find some blue mason jars on the secondary market, they can be sold for much higher prices than other color mason jars.
It is important to note that not all blue mason jars are considered rare; it depends on the age, pattern, and maker of the jar. If you’re looking for a rare blue mason jar, it’s best to research the specific item you’d like to purchase beforehand so you know what you’re looking for.
What Mason jars are worth a lot of money?
Mason jars that are worth a lot of money are collectors items, typically old, rare, or unique jars that have significant historic or monetary value. Clear glass jars with zinc, glass, or porcelain lids tend to be the most valuable, as well as Mason jars with interesting or unusual embossing, such as the Ball Perfect Mason or the Mckee Perfect Mason.
There are also certain jars that have a unique or rare color, and even variants with unique shapes. Some of the most valuable jars include the rare Blue Quart-sized Atlas E-Z Seal jar, the Atlas H over A Mason, the early Ball Ideal with ground lid, and the amber Quart-sized Mason’s Patent 1858.
These jars could be worth anywhere from $30 to $3,000 depending on condition, rarity, and age.
Are Old Ball Mason jars worth anything?
It depends on the age, size, and condition of the Ball Mason jar. Generally speaking, the older and more rare the jar is the more it is worth. Some Ball Mason jars can be worth thousands of dollars. For example, Ball jars made in 1933 with the embossed “Ball” and “Perfect Mason” on them have been known to sell for upwards of $3,000.
Colors can also make a difference. A green jar may be worth more than a clear jar or vice versa. It all depends on the jars rarity and often takes research and an understanding of the historical context of the jar to accurately assess its worth.
Generally, though, antique Ball Mason jars are very collectible and may be worth something to a collector.
Is it safe to store food in old Mason jars?
In general, it is safe to store food in old Mason jars as long as the jars are intact with no chips or cracks in the glass or rims. However, it is important to inspect the jars for any signs of deterioration or damage before storing food in them.
Additionally, if the jars have rubber seals, such as with certain wide-mouth jars, make sure the seals are intact and not worn or brittle. Be sure to use the correct lids, which should fit securely against the jar and not allow air or moisture to enter.
It is not recommended that you use older jars with zinc lids, as these were known to corrode and actually shatter when the jars were heated. Furthermore, it is important not to process jars that have any cracks or chips in them and discard them instead.
When storing food in Mason jars, it is also important to make sure they are in a cool, dry place, as extreme temperatures can cause glass jars to crack and break. Lastly, as with any food storage containers, cleaned them thoroughly before and after use.
Do Mason jars have a shelf life?
Mason jars do have a shelf life, however it depends on the type of jar and the materials used to make the jar. Traditional Mason jars made of glass and metal can last for decades, and are generally considered to be shelf-stable, although their seals may start to degrade over time.
Plastic and silicone Mason jars have shorter shelf lives, since they are prone to cracking, discoloring, and absorbing odors. Other factors, such as whether or not the jar is stored in a cool, dry place, can affect its shelf life.
In general, it is best to follow the manufacturer’s recommendations for shelf life, as this will ensure that your Mason jars remain safe and usable.
How do you know if a canning jar is safe?
To determine whether a canning jar is safe for use, you’ll want to look for certain features of the jar itself. Firstly, make sure the lid has an airtight seal so that the contents of the jar remain safe and secure.
Look for any cracks or breaks in the lid, or any signs of rust or corrosion. You’ll also want to make sure the jar itself has no cracks or chips, as these can create openings that allow bacteria to enter the jar.
Additionally, check the glass for any bubbles or discoloration, as these can indicate the jar has been exposed to too much heat. If you’re reusing an old jar, make sure the jar is designed for canning—some jars may not be safe for this purpose.
Finally, as a safety precaution, it’s helpful to sterilize the lid and jar prior to canning. This can help reduce the chances of contamination.

Can mason jars be spray painted?
Yes, mason jars can be spray painted. However, if you want the paint to last, some preparation steps are necessary. First, clean the jar thoroughly with soap and warm water, then rinse and let it dry.
Next, sand or otherwise roughen the jar to create a surface that will hold paint better. You may also need to apply a primer or base coat so that the paint will adhere better. Once the primer is dry, carefully spray the jar with an even coat of spray paint, then allow it to dry completely.
You can also add a coat of clear sealant afterward to help preserve the paint job. With the proper preparation, mason jars can make colorful and unique decorations for your home or craft projects.
