As a colorful Mother’s Day gift for grandma, the boys and I made some tinted mason jars. How to tint mason jars is actually incredibly easy for the kids to do!

Last summer, my sister and law and a bunch of us girls colored mason jars for her and my brother’s wedding. I called her for a quick refresher of how to do it.

This is one of our 10 non-flower crafts for mom for Mother’s day and its so simple!

I love when I have everything in my supply cupboard already! Mod Podge would be the only thing I don’t restock up on all the time, but did happen to have some for this. But, like I mentioned, school glue works too for this, just add a bit of water to it.

Simple method of how to tint Mason jars:

The boys mixed their own colored glue.

I dumped some Mod Podge in some glass dishes and they added food coloring of their choice and stirred it up.

They got right to painting the mason jars. They can paint either the inside or the outside for this craft, it doesn’t matter.

Henry painted the inside of his first jar.

How to tint mason jars a solid color: This is what we did for my brother’s wedding. We poured a little of the colored glue into the glass jars and swirled it around to cover the entire inside and then let it drip out.

I told them both to get creative and paint with multiple colors to see them marble together.

George painted the outside of his.

He turned it upside down to paint the bottom of it.

George wanted to use all three colors of glue on his jar, which is just fine.

I just made sure to tell him to keep them separate on the jar or all three colors together would probably make brown. He was very careful to paint the colors next to each other and not mix them all together.

On their second jars, they each tried painting their jar the other way.

George painted the inside of this one, and Henry painted the outside of his jar.

As for the finished product, I think they both look the same, whether they were painted on the inside or out. However, you can feel the glue mixture on the ones that were painted on the outside.

If you’re prefer a smooth finish, go with painting the inside.

I was hesitant to having the kids do it that way, I thought it would be hard for them to reach in with the paintbrushes. But neither of them had problems. But they also did the inside on the wider mouth Mason jars.

Its always nice to see them being creative side by side.

Getting along. For the most part.

They had a little argument over the blue paintbrushes because somehow there ended up being three of them and George thought there should only be one.

The kids painting and learning how to tint Mason jars

After they’re done painting, they have to drip, especially the ones that were painted on the inside. So we tipped them over to drip for awhile.

The one good thing about the kids painting the inside of the jars is that I could write on the bottom of the jars with permanent marker the date and their initial so I knew whose was whose.

We really should have let them drip for a good hour or so, but we were in a rush and it was only a few minutes. [Hey, we were going to go roast hot dogs and s’mores on an open fire!]

Let excess paint drip off Mason jars

Then I popped them in oven at the lowest temperature I could, 175F for about 10 minutes with them still upside down.

Then I turned them over and baked them for another 20-30 minutes or so.

I took them out and we went to roast our hot dogs while they cooled off.

They turned out so pretty with marbled coloring. I can see a few thick spots though, so I do think that if I let them drip for a while longer before putting them in the oven, it would be a more even coating. They still look pretty awesome though and I’m super excited to give these to Grandma for Mother’s Day.

Now we just have to deicde what we want to fill them up with! Any suggestions?

Henry is 6 years old. George is 3.5 years old.

    The look so pretty!! I am sure my 3.5 year old would LOVE LOVE LOVE doing this project.

    Maybe you could put flowers in them – use it as a vase? It’s spring, after all! Or if the recipient is a chocolate lover, you could put in some Hershey’s Kisses – show the love! If a health nut, maybe a home-made (or not) trail mix, or even some dried fruit.

    I look forward to reading more ideas. Thanks so much for the neat project idea!

    BTW.. I was wondering if it is safe to put anything edible inside the jars that were painted inside…?

  2. Tricia says

    Would these be able to hold water after they dried? I love them and Nana always has flowers on her table from her garden and it would be perfect for the kids to make if they could hold water….

    • Jamie Reimer says

      Tricia – good question. I think so. Mod Podge isn’t washable (unless you buy the washable stuff) – so I think it would last. It can be ‘peeled’ though, so I think as long as water is just sitting in it (instead of like scrubbing, or a dishwasher) it would last. But then again, I haven’t tested. Would love to hear if anyone else has had experience.

  3. Sheila says

    Did you just use regular mod podge or a metallic finish one? I just experimented with one jar but it looks more tinted and doesn’t have an opaque and metallic finish. Thanks for your help!

  4. Iva says

    Hi Jamie, these look great! Do you have a sense it Elmers white glue might work instead of Mod Podge? We have lots of glue at home and would be fun to use for this project. Thanks!

    • Jamie Reimer says

      Yes Iva. When we did the vases for my brother’s wedding, we ended up using wood glue and elmer’s glue. I think any type of glue will work. If you want to be able to wash it when its done, just make sure its not a ‘washable’ glue.

  5. Shirley says

    Hi..Sissy I do believe the Neon was what gave these the look that they have. These are really nice looking jars.
    I would not suggest using the jars that were painted INSIDE for water as the mod podge will eventually wear off. If it is on the outside, it will be fine.
    If you clean these I would also suggest just wiping it down on the one painted on the outside. They can be washed in the sink but I would suggest doing so quickly and drying them completely immediately after they have been washed.

    I’d like to start off with saying how wonderful your site is! My Wee one is 3 and we love love love your activities on here! Thank you! So I have tons of glass jars left over from used candles, so we’re going to make new candle holders with this! My question for you before we do that is, is it safe since, glue will be on the inside or should we paint the outside? And for something to use for outdoor candle decor I would think to use a clear Acrylic spray to seal it and help guard against rain and such, but again do you think that’s safe to burn? I’m sorry for so many questions, but I’m certain you’d have some great/helpful answers! I appreciate the help!

    • Bayless says

      Bell Mason jars, and any other type of glass jar, are made for heat. They are traditionally used for canning, which involves pressure cooking them. This means they should be able to withstand the 175 degrees necessary for this project. I made these jars and they turned out just fine. In fact, after just about two minutes they’re cool enough to touch. Your jars should be able to go in the oven without a problem.

  7. Meghan says

    Thanks so much for this! I used this project tonight in my Sunday School class. My students are using them for gratitude jars. We will put slips of paper in each week with things they are thankful for.

  8. Rachel says

    My son is using these as his business project for school. I’m thinking we will paint the inside. Any suggestions for stuff to put in the finished product? He will be selling these at his school.
