Can You Store Oil Paints in Glass Jars?

If you like to premix colors for future use, or you just don’t like the containers your oil paints come in, you might be wondering if there is another way that you can safely store your oil paint. It is incredibly important that there is no air in the container, so what exactly can you use?

So, can you store oil paints in glass jars? Yes! Glass jars are a pretty good option for storing oil paints. The biggest thing is making sure that the jars are always full and completely airtight. It can be hard to make sure the jar is always full without constantly buying paint to replace what you use. Luckily, there is a simple solution to this problem.

Before you store your oil paints in a glass jar, it is important to make sure you are completely prepared. If the paint isn’t enough to completely fill the jar, you will need to have something that you can put in the jar to get rid of the air. For instance, glass marbles would make a great option.

How Do You Store Oil Paint in a Jar?

The first thing you need to do before storing oil paint in a jar is make sure the jar is clean and dry. You can clean it out with some warm soapy water, then give it plenty of time to dry. Smaller glass containers will work best because they are more likely to hold all of your paint without leaving air space in the jar.

Start filling the jar with the oil paint. If it fills all the way to the lid, then all you need to do is close the airtight lid as tightly as you possibly can. This will prevent any air from getting into the paint and causing it to cure.

My favorite and top pick is always Arteza Oil Paints. They have so many different colors, and the quality is amazing! I usually use Arteza Paints for all my projects.

If the paint doesn’t fill all the way to the lid, you will need to put something in the glass container to fill up the extra space and get rid of air. The best thing for this job is going to be glass marbles because the oil paint won’t react with them in a negative way. After you get the jar full, close it as tightly as you can.

Make sure you are storing the glass jar in a safe place that is away from direct sunlight and heat sources. It is best to store in a dark and cold area like a closet. This will protect your paint and your home from a potential fire.

How to Dispose of Oil Paint

Since oil paint is made with oils and chemicals that can be dangerous, it is important to make sure you are properly disposing of the product. Oil paint is considered to be a hazardous waste, so you should not just throw it in your regular trash or pour it down the drain. Unfortunately, oil paint has very limited options for disposal

The best thing to do is contact your local hazardous waste facility to see what their specific requirements are for disposal. In some cases, they will come pick the product up for you and in others you need to take it to them.

When you dispose of oil paints, it is important to make sure the paint is cured and dry. You don’t want the paint to still be liquid because it can cause harm to the workers of the facility. However, you don’t want to leave multiple containers of oil paint out to dry because it can cause you harm.

Best Oil Paint Containers

Glass is a great option for storing oil paints, but it isn’t the only option. While you might want to stay away from plastic containers because oil paints can eat through the plastic, there are other materials that make great oil paint containers. 

Polyethylene and high-density polyethylene are the most recommended materials for storing oil paints. These materials resemble plastic, but they are much stronger. This gives them the ability to stand up to the chemicals in oil paints.

Metal containers are another great option for oil paints, but they are prone to rusting and they aren’t the most airtight container. Metal should only be used when storing oil paints for a very short period of time to prevent the paint from being compromised.

How Do You Store an Oil Painting to Dry?

Oil paint takes a long time to dry, so you need to keep it somewhere safe. This will prevent any damage from occurring to the painting during the drying process and save you from feeling a ton of frustration. The most important thing to remember is your painting needs to lay flat when it is drying because the paint will run and ruin the painting.

If you don’t have a flat surface that is safe from damage, you might want to consider purchasing a paint drying rack. This will give you a fat surface that is also safe from things like fingerprints and pet prints forming in the wet paint.

If you don’t have space for a paint drying rack, you can also store the painting on a high shelf or a bookshelf if you have one. You might need to move some books to make it work, but this is a great alternative. It is also a good idea to keep the painting away from any heat sources or direct sunlight.

What Happens When Oil Paint Freezes?

The freezing point of oil paint is pretty low at -4 degrees Fahrenheit. However, if you live in the north, you are highly likely to experience temperatures this low in the winter. In this case, your oil paint will start to freeze, and it might have an impact on the quality.

When oil paint freezes, it runs the risk of impacting the emulsion of the paint. When it thaws, both the texture and consistency of the paint can be ruined. This makes it harder, or impossible, to work with the paint. However, before you run and buy new paint, you can check the consistency by slowly thawing the paint.

The easiest, and safest, way to thaw oil paint is to bring it in your home and expose it to room temperature. This will require some waiting, but this is the best way of saving your paint and being able to use it again. After it’s been thawed, stir the oil paint to check the consistency.

If the consistency looks normal, you can continue using it. If the consistency looks off at all, you should just go buy some more oil paint.

Final Thoughts

If you like to pre-mix paints, or just don’t like the container your oil paints come in, you might be wondering how you can safely store it. Glass jars are a great option because oil paint won’t eat through the material. You should avoid plastic containers unless it is made from polyethylene or high-density polyethylene, which are extremely durable and can resist the chemicals in the oil paint.

Whichever you choose, you need to make sure the container is airtight. If the oil paint doesn’t fill the container to the top, you will want to add some glass marbles into the container to get rid of the air. When the jar is full, close the airtight lid as tightly as you can.
