What concrete vessels are

Concrete candle vessels are containers cast from cement, concrete or similar mineral materials such as jesmonite or terrazzo. They are popular for modern, Scandinavian and industrial-style candles. Their weight makes them stable, they come in many natural tones, and once the candle is finished they can be reused as planters, pen holders or trays.

The main difference from glass is porosity. Raw concrete absorbs oils, so an unsealed vessel can soak up wax and fragrance and develop dark stains or even leak through the walls. Good vessels made for candles are sealed inside with a heat-resistant coating. They pair well with soy wax and coconut wax and look great with a wooden wick.

What to look for when buying

• Sealed interior. The listing should say the inside is sealed or waterproofed for candles. If not, you will need to seal it yourself with a product rated for heat.
• Wall thickness. Thick walls insulate better and prevent hot spots. Avoid very thin, lightweight vessels.
• Smooth, flat base. A cork or felt pad underneath protects furniture.
• Shape. Wide, straight vessels burn most evenly. Bowls with a narrow top or very deep shapes are harder to wick.
• Finish and color. Natural gray, white, terracotta and terrazzo flecks are common. Remember that oil stains show most on light colors.
• Lids. Some vessels come with wooden or concrete lids, which are handy for curing and gifting.

Common sizes

Concrete vessels often have thicker walls, so the inside diameter can be much smaller than the outside. Always measure inside and check the wick calculator.

Size	Typical inside diameter	Approx. wax	Notes
Small (about 4 oz / 120 ml)	2–2.4 in (5–6 cm)	3 oz (85 g)	Minis, gifts, tests
Medium (about 7 oz / 200 ml)	2.8–3.1 in (7–8 cm)	5–6 oz (140–170 g)	Most common size
Large (about 12 oz / 350 ml)	3.5–4 in (9–10 cm)	9–10 oz (260–290 g)	Often needs two wicks
Bowl (wide and shallow)	4.5 in+ (12 cm+)	varies	Multiple wicks, test carefully

How to use and clean them

Dust off the vessel with a dry cloth. If it is unsealed, apply a heat-resistant sealant inside and let it cure fully according to the product instructions. A simple test: put a drop of oil on the inside; if it soaks in quickly, it needs sealing.

Fix the wick with wick stickers, warm the vessel slightly (concrete holds cold for a long time), and pour at your wax's recommended temperature. Concrete keeps heat longer than glass, so the candle cools slowly, which is good for a smooth top. Keep fragrance load within the supplier's maximum; excess oil is more likely to seep into the walls. Our fragrance load guide explains how to calculate it.

To reuse, warm the outside gently with a heat gun or set it in the freezer, remove leftover wax, and wipe the inside with a paper towel. Avoid soaking concrete in water; wipe it with a damp cloth and let it dry completely.

Safety

• Use only vessels that are sealed and free of cracks.
• Burn on a heat-resistant surface; the base can get warm.
• Stop when about 1/2 in (1 cm) of wax remains.
• Keep wicks trimmed and never leave a burning candle unattended.
• Test burn every new vessel shape with your wax, wick and fragrance before gifting or selling.

Common mistakes

1. Pouring into unsealed concrete. Oil stains and leaks are almost guaranteed.
2. Measuring the outside diameter. Thick walls make the inside much smaller.
3. Pouring into a cold vessel. Wax can pull away or crack on the surface.
4. Overloading fragrance. More oil means more chance of seepage.
5. Washing with lots of water. Concrete absorbs moisture, which affects the next pour.

Pros and cons

How to use concrete candle vessels, step by step

1. Check whether the inside is sealed with a drop of oil.
2. Seal it with a heat-resistant product if needed and let it cure.
3. Measure the inside diameter and choose your wick.
4. Attach the wick with a wick sticker and warm the vessel slightly.
5. Pour your wax at the recommended temperature.
6. Let it cool, cure and do a full test burn.

Tips

• Add a cork or felt pad to the base to protect furniture.
• Light-colored concrete shows stains most, so seal it well.
• Wooden wicks suit the modern look.
• Keep fragrance load moderate and within the datasheet maximum.
• Store empty vessels dry to keep them ready for pouring.
