How to Paint the Inside of a Mason Jar

How to Paint the Inside of a Mason Jar

Mason jars are usually clear, but you can find them in a wide range of tints and colors. However, if you have some clear mason jars that youd like to transform into decorative items, there are easy ways to paint the inside of them yourself. You can coat the inside of a mason jar with paint to provide an opaque color, or you can tint the inside of a mason jar with food coloring for a transparent color. The paint or food coloring will dry on its own, but you may also cure it by placing the jar in your oven if desired.


[Edit]Coating a Mason Jar with Acrylic Paint

  1. Mix acrylic paint in a bowl to achieve the desired shade. Measure out 2 tablespoons (30 mL) of acrylic paint and pour it into a small bowl. You can use a 50/50 mixture of 2 different colors to achieve a specific shade or add a few drops of 1 color to another to adjust the shade slightly. Mix the paint colors together well using a spoon or fork.[1]

    • For example, you could use 1 tablespoon (15 mL) each of blue and white to create a pastel or light blue shade. Or, add a few drops of green to 2 tablespoons (30 mL) of white paint for a light mint green paint.
    • If you dont want to adjust the shade of your paint before coloring the inside of the mason jar, pour it directly into the jar.
  2. Pour the paint into a clean, dry mason jar. Wash out the jar with dish soap and water, then rinse it out thoroughly. Let the jar air-dry upside down or use a paper towel to dry it out. When the jar is dry, pour the mixed paint into the jar.[2]

    • If youre painting the inside of multiple jars, measure out 2 tablespoons (30 mL) of paint per jar.
  3. Twist and turn the mason jar to coat the inside of it. Swirl the paint around in the jar by slowly turning the jar on its side and rolling it around in your hand. Keep turning and tilting the jar until the inside of it is completely covered in paint.[3]

    • This may take a few minutes since the paint will move slowly. However, do not use a paintbrush as this will result in an uneven appearance.
  4. Place the mason jar upside down on a piece of cardboard to dry. After the inside of the jar is completely coated with the paint, place the jar on a piece of cardboard. The excess paint will continue to drip down, so pick up the jar and move it to a different spot on the cardboard about once every 15 minutes.[4]

    • The jar will take several hours to dry, so plan to wait 24 hours before you use the jar for decorative purposes.
    • If you dont have cardboard, use a few layers of newspaper or paper towel to catch the paint that drips down.

[Edit]Tinting a Mason Jar with Food Coloring

  1. Combine water and food coloring in a small bowl. Add 1 tablespoon (15 mL) of water into a small bowl. Then, add 20 or more drops of food coloring to the water and stir the food coloring into the water until they are well-combined.[5]

    • You may use any color or combination of colors you like to tint the jar. Try using blue food coloring for a blue-tinted jar or red and yellow for an orange-tinted jar.
  2. Pour the mixture into the jar and add 1 tablespoon (15 mL) of white school glue. Use a fork or spoon to stir the food coloring a water mixture with the glue right inside of the jar. Stir until everything is well-combined.[6]

    • You can also use clear PVA glue if you dont have school glue.
  3. Twist and turn the jar to coat the inside. Pick up the jar and start twisting and turning it in your hand to coat the inside of the jar. Turn the jar to the side and roll it around in your hands to get an even layer of the food coloring mixture all over the inside of the jar.[7]

    • Do not turn the jar upside down until the inside is fully coated with food coloring. Then, pour the excess into the small bowl to use on another jar or discard it.
  4. Place the jar upside down on a paper towel to dry. Use 2 to 3 layers of paper towel to catch any excess glue that drips down while the jar is drying. Pick the jar up every 15 minutes for the first hour to prevent the glue from collecting and adhering to the paper towel. Then, turn the jar right side up and let the jar dry overnight.

    • If you dont have paper towels, you can also use a few sheets of newspaper or a piece of cardboard to catch the glue.
    • Make sure to keep the jar away from pets and children while it dries.

[Edit]Curing the Paint or Food Coloring

  1. Pre-heat your oven to . Turn your oven up to this temperature and allow about 10 to 15 minutes for it to reach it. Do this right after you finish painting or tinting the inside of your jars to cure the paint or food coloring while it's still wet.[8]

  2. Bake the jar upside down for 15 minutes. Place the jar upside down on a cookie sheet lined with wax paper. Then, carefully put the cookie sheet in the oven. Set a timer for 15 minutes to keep track of how long the mason jar is baking.[9]

    • While the mason jar is baking, try making another jar or simply use the time clean up your supplies.
  3. Turn the jar over and bake for another 15 minutes. After the time is up, put on a pair of oven mitts and carefully remove the cookie sheet from the oven. Then, turn the jar over so that the open end is facing up and put it back into the oven. Bake it for another 15 minutes.[10]

    • Do not touch the mason jar with your bare hands! It will be very hot and it will burn your skin.
  4. Remove the mason jar from the oven and let it cool. Use oven mitts to remove the cookie sheet from the oven and set it on a potholder or trivet. Then, let the mason jar sit on the cookie sheet until its completely cool. This will take about 20 to 30 minutes.[11]

    • After the mason jar is cool, use it for all your decorating needs!


  • Put down a layer of newspaper or paper towels before you begin. This will help to protect your work surface. You may also want to put on an old t-shirt before you begin.
  • Fill your painted or tinted mason jars with silk flowers for a simple centerpiece, or place a single tea light candle inside of one for decorative ambiance.
  • If you need to wash the jar after painting it, use a small amount of dish soap, lukewarm water, and a non-abrasive sponge. Dont scrub the jar or put it into the dishwasher.


  • Dont store food in a mason jar after you paint or tint it.
