A Day in the Studio: Crafting Durable, Hand-Poured Cement Candle Jars

BiirCo Candle Jars

Crafting our cement candle jars is an involved, careful process that ensures each jar is sturdy and stylish for candles and then as a reusable home decor piece. Here’s a glimpse into a day in the studio creating these durable, hand-poured jars:


  • Starting with Clean Molds: We begin by washing the molds to ensure a smooth, clean finish on each jar. Clean molds help prevent imperfections, setting the foundation for a quality jar.


  • Cement Station Prep: Next, it’s time to mix up the cement! Depending on the jar color, we create a specific blend recipe, adding pigments for natural, earthy tones. Safety is key—so with eyewear, gloves, and a facemask on, we’re ready to get started.


  • Blending Cement and Pigment: To get a smooth, flawless mixture, we add reverse osmosis, filtered water as needed and blend the cement and pigment until it’s fully incorporated, ensuring a uniform look with no lumps for each jar. This part involves moving quickly but carefully as to not bubble the mixture.


  • Pouring and De-bubbling: Once blended, we pour the cement mixture into the molds slowly. A gentle but thorough tapping ensures air bubbles are released, resulting in a dense, solid jar that’s built to last.


  • Curing Process: The poured jars sit in the molds for a minimum of 4 hours to begin their initial cure.


  • Demolding and Smoothing: After curing, we demold and sand the bottoms for a smooth, balanced surface. Then, each jar is submerged in water for 24 hours to further strengthen the cement, ensuring it’s ready to handle future uses.


  • Drying and Final Sealing: After wiping the jars clean, they air dry for 5 days, followed by sealing with a safe, non-toxic cement sealer. This sealing process adds an extra layer of protection, enhancing both durability and the jar’s visual appeal. The jars then dry for an additional 2 days to lock in the sealer.


This process may be time-intensive, but it ensures that each cement jar is a high-quality, long-lasting product. With its durable design, each jar can be reused as a stylish home decor piece—whether as a planter, storage container, or decorative element—long after the candle has burned. Each step reflects our commitment to quality and safety, giving you a handcrafted jar that’s as sustainable as it is beautiful!


A Unique Jar Every Time

While we follow the same precise process for each jar, every single piece is unique. The blending of cement and pigments naturally creates subtle patterns and textures, giving each jar its own distinct character. Some may have marbled effects, while others feature soft, organic lines or variations in shading. This individuality is what makes each jar truly one-of-a-kind, a piece of art as well as a practical item. When you choose one of our cement jars, you’re not only getting a high-quality container but also a unique, handmade piece with natural beauty in every pattern.
