Mason jars are incredibly versatile, used for everything from canning and food storage to crafting and decoration. But have you ever considered making your own custom lids? These concrete mason jar lids are not only functional but also add a touch of industrial chic to your kitchen or pantry. The process is surprisingly simple and requires minimal materials, making it an ideal weekend project for DIY enthusiasts of all skill levels.

This project draws inspiration from the “Crafts” section of Mason Jar Nation. Unlike some other intricate mason jar crafts, this project is designed to be easy and accessible for everyone. You don’t need any specialized skills or tools to create these stylish concrete lids.

But why concrete, you might ask? Concrete provides a modern, industrial aesthetic that contrasts beautifully with the classic design of mason jars. It’s also incredibly durable, ensuring your lids will last for years to come. Plus, concrete lids add a nice weight to your jars, making them feel more substantial and preventing them from tipping over easily. They’re also perfect for using mason jars as canisters for storing anything from flour and sugar to coffee beans and spices.

In the 19th century, mechanical engineer William Ward, driven by a deep fear of fire, sought to build a fire-proof home for his family. This was no small concern in an era when open flames were essential for survival. Lighting, cooking, and heating, combined with common household combustibles, made the threat of fire a constant worry. But William Ward was not just any engineer; he was a visionary who understood the potential of concrete.

With the help of his friend and architect, Robert Mook, Ward constructed a reinforced concrete home in Port Chester, NY. Completed in 1875, this groundbreaking structure was the first of its kind in the United States.

Initially, the fire-resistant home was ridiculed as “Ward’s Folly,” with critics predicting its imminent collapse under its own weight. However, “Ward’s Castle” still stands today, largely unchanged, a testament to Ward’s ingenuity and the durability of concrete. The naysayers were proven wrong, and Ward’s creation marked a turning point in the modern use of concrete in the country.

From sturdy facades to elegant interior elements like flooring and countertops, concrete has become ubiquitous. And now, it’s even topping a Mason jar, bringing a touch of modern durability to a classic household item. —From MASON JAR NATION, by JoAnn Moser, Cool Springs Press 2016

Materials You’ll Need

  • Empty plastic cylindrical container slightly larger than the jar band (an empty cake frosting container works well)
  • Utility scissors or tin snips
  • Craft glue, such as E6000
  • 1 mason jar lid and band to fit the jar
  • Empty container for mixing the concrete
  • Water
  • 1 cup of Portland cement
  • Cooking spray
  • A few pebbles for weight
  • 1 Mason jar with a regular-size opening

Step-by-Step Instructions: Crafting Your Concrete Lid

Follow these simple steps to create your own stylish and durable concrete mason jar lids.

  1. Prepare the Mold: Cut down the edges of the frosting container to approximately 2 inches in height. This will serve as the mold for your concrete mix. Ensuring the mold is the right size is crucial for achieving the desired lid thickness and appearance.
  2. Assemble the Lid and Band: Apply craft glue to join the mason jar lid and band together. Allow the glue to dry completely. This step ensures that the lid and band are securely attached, providing a stable base for the concrete.
  3. Mix the Concrete: In the empty container, gradually add clean water to 1 cup of Portland cement until you achieve the consistency recommended on the cement packaging. The mixture should be smooth and pourable, similar to a thick pancake batter. Avoid adding too much water, as this can weaken the concrete.

  1. Prepare the Mold for Pouring: Lightly coat the inside of the plastic mold with cooking spray. This will prevent the concrete from sticking to the mold and make it easier to remove the lid once it has cured.
  2. Pour the Concrete: Carefully pour approximately 1 inch of the mixed concrete into the mold. Ensure that the concrete is evenly distributed across the bottom of the mold.
  3. Nestle the Lid Assembly: Gently nestle the assembled lid and band into the mold, allowing it to displace the concrete. Position the lid so that the band’s edge is level with the top of the concrete.

  1. Add Weight: Place a few pebbles inside the lid to weigh it down and ensure it remains submerged in the concrete until the band’s edge is equal to the top of the concrete. This step helps prevent the lid from floating to the surface as the concrete sets.
  2. Cure the Concrete: Allow the concrete to cure completely, following the instructions on the Portland cement packaging. This usually takes at least 24-48 hours. Patience is key here; allowing the concrete to fully cure will ensure its strength and durability.
  3. Remove from the Mold: Once the concrete has cured, carefully coax the entire part out of the mold. If it’s sticking, gently tap the mold to loosen it.
  4. Attach to the Jar: Twist the new concrete lid onto your mason jar. Your stylish and functional concrete mason jar lid is now complete!
