can you epoxy glass jars?

Does epoxy resin stick to glass? That’s a great question. Epoxy is a type of adhesive that’s used for bonding things together, like plastic and metal.

It’s also used for sealing cracks in cars, making sure that the paint on your car doesn’t wear off as quickly when it gets chipped away by rocks and debris during long drives through the mountains.

But what if you want to use epoxy on glass jars? Can you do that? And if so, how do you go about doing it safely? Or what about using resin instead? Can you use epoxy resin in Mason jars or other types of containers made from glass? Let’s dig into all of these questions today!

Can you use epoxy on glass jars?

Can you resin glass jars?

Absolutely! You can put your favorite flowers in them, or you can use them to store jewelry. The possibilities are endless. Here are some suggestions:

  • Use your glass jar to store food. If you have a large container, then it will be great for storing spaghetti sauce or any other canned foods that need airtight storage conditions.
  • Use your glass jar as a vase for flowers and plants. You don’t have to worry about the water leaking out because of the tight seal this material provides. This means that your flowers will stay fresh longer than usual, which is especially important if they’re expensive or hard-to-find varieties of plants/flowers (or even just regular ones).
  • Use small glass jars around the house or office as decoration pieces by filling them with sand so that they look like miniature versions of aquariums/terrariums/etc.

How do you resin Mason jars?

You’ll need to clean the jars and lids before you begin. Wipe them down with a damp cloth to remove any dust or dirt that may have accumulated over time.

Next, fill each jar almost all the way with water, leaving just an inch or two empty at the top. You want enough space for the resin to settle below its surface so that when it hardens and shrinks down into place, there will still be room for air exchange between your food and your Mason jar lid.

Pour in a generous amount of resin (following instructions on your packaging) until all of it has been absorbed by both sides of each jar’s walls—this will help prevent leaks later on when everything dries out after solidifying into place!

Once everything has hardened up inside their respective vessels (usually overnight), rinse them out under running water one last time before letting them dry thoroughly before using again!

Can you put resin in a jar?

You can use epoxy resin to seal a jar.

To seal your jar, you will need:

  • glass mason jar (or another drinking-glass type) with a lid that accepts cork
  • clear epoxy resin, such as Loctite 5 Minute Epoxy Kit or JB Weld Quick-Cure Epoxy Putty Kit
  • stir rod and mixing cup if you are using the Loctite kit (not necessary with the JB Weld kit)

Does epoxy resin stick to glass?

In short, yes! Epoxy resin will stick to the glass.

When you mix epoxy resin and hardener together, you wind up with an adhesive that’s really sticky. This means that the resin will stick to both of the surfaces—the glass jar and the jar lid—and they’ll both stick together because of it.

How do you prepare glass for epoxy?

The glass needs to be clean and dry in order for the epoxy to work well. If your jar is not clean, you can use a glass etching solution to clean it.

Use an old toothbrush or some elbow grease with a wet paper towel and wipe away any dirt or fingerprints from the glass surface.

Once it has dried, cover your jar with another piece of paper towel and press hard on the sides of the jar until all fingerprints are removed.

What does epoxy not stick to?

Epoxy doesn’t stick to most plastics, but it can bond with some soft plastics like PVC. It also doesn’t stick well to rubbers, metals, or ceramics—though there are other adhesives that can be used in those cases. Epoxy won’t stick to stone, wood, or glass because these materials have no free moisture (like epoxy does).

Is resin safe for food?

Epoxy resin is food-safe. When used properly, epoxy can be used to seal jars, bottles, mason jars, and other glass containers without any issues.

You can even use it on metal lids or caps as long as you pay attention to what glue you use (more on this below). The only thing that is not safe with epoxy resin is using the wrong solvent for your project.

I urge you to make sure that you’re using the right type of solvent for whatever project you have in mind before going forward with any sealing process like this one!


Remember that resin is a sticky substance, so you’ll want to make sure you have plenty of paper towels and rags on hand for cleanup.

Also, clear epoxy resin can sometimes turn yellow over time if it isn’t used in a timely manner. If this happens, there are special additives available from craft stores that will help prevent discoloration from occurring again.

You may also want to consider adding other materials into your mixtures such as glitter or metallic flakes before pouring them into your jar so they will be part of the final product too!
