My bestie was having a baby shower and I was in charge of decorations. It was going to be outside and we were using all sorts of bright colors as the theme. (No, they're not finding out.)
I wanted to do something fun and was in a Mason Jar kick. So I looked up how to tint mason jars. The ones I saw online were BEAUTIFUL! Mod Podge and food coloring.
I followed the directions carefully. Mix food coloring with a little water. Add to Mod Podge (glossy). Spin and cover entire inside of jar. Pour out excess. Bake upside down in 200 degree oven for about 1/2 an hour. Check. If not clear, back another 20 minutes and keep checking.
Well, mine never got really clear. They were more streaky and gloppy.
I ran out of Mod Podge (I was using a trial-size bottle) and looked around for something else. Something clear. Something that would mix with water and dried hard. I dug though my art boxes, drawers, storage totes, closets (it's embarrassing...) Liquitex to the rescue! I found a bottle of Pouring Medium and decided to give it a try.
NOTE: Liquitex Pouring Medium is NOT food-safe. Do not eat/drink from the tinted jars!
Once again, I mixed the food coloring with a little water to break up the pigments. Then I mixed some pouring medium in with it. I kept it dark because I knew it would dry lighter. I tilted the jars to totally coat the insides, then turned it upside down on a paper bag (to catch the drippings) After about 1/2 an hour, I did a second coat in the same way. I left the jars upside down for another 1/2 an hour or so, moving them once and awhile to make sure they were not going to stick to the paper bag.
I then moved them to wax paper (still upside down) and let them dry for the night.
The next morning, I turned them right-side up and let them finish drying for a couple days. Just to be safe.
(Worth noting again) NOTE: Liquitex Pouring Medium is NOT food-safe.

The finished jars as centerpieces. I crinkled some decorative cellophane and put the rings back on with a cut artificial flower (I had to travel 4 hours with the decorations. I didn't want to tempt fate with real flowers or hope to find a florist.) they turned our lovely and with the cellophane inside, you could hardly see the streaks & glops from the green Mod Podge batch.
