Those used to be perfectly ordinary mason jars. Then we dyed them to get these awesome retro colors, so now they look like they’re made of sea glass.
What must seem like a complicated process is actually pretty easy to do once you know how. You need Elmer’s glue and food coloring. You should also have some ramekins and old newspapers on hand when you start, for best results.
Start by mixing food coloring with a little bit of water in the ramekins. Keep the colors separated – one color for each ramekin. Once properly mixed, move onto the mason jar. Pour a few teaspoons of Elmer’s glue into the mason jar, then pour one ramekin of food coloring and water mixture into it. Stir vigorously to mix it all together. Keep the mixture moving until it’s fully incorporated as you don’t want the glue drying up.
You’ll know when its fully incorporated because you’ll be left with a thick consistent cream that’s a lighter color than what you started with. Now take out the stirrer and pick up the mason jar. Carefully twist and roll the jar around so that the mixture inside moves around and coats the entire inside. Don’t let it drip out as the color is really hard to get out of anything. Do this for a while to make sure you’ve covered everything. By now some of it should have started to dry.
Pour off any excess and then turn the mason jar upside down over a newspaper and leave it to dry. Half an hour should be enough. If you want clear mason jars then you need to dry it further, so place them upside down on some cookie paper and let them dry inside an oven for 10 minutes. Then turn them over and heat for another 10 minutes.
Check to make sure there aren’t any streaks of color left. Just stick it in the oven for another few minutes to get rid of any streaks. Let us know in the comments if you have any questions.
