Are ceramic containers safe for candles?

Once you’ve gathered your candle-making gear and materials, a significant decision lies in selecting the perfect vessel for your candle. Curious about which options ensure safety and which should be avoided? Allow us to guide you through some recommendations and precautions in this realm! While a coconut shell might seem like an exotic choice for a candle, it might produce more blaze than tropical vibes.

Let’s start with the apparent: your container must be heat-resistant. While most glassware, ceramics, and pewter can serve the purpose, it’s crucial to delve deeper:

Glassware Selection

When opting for glassware, ensure it can endure heat, retain wax effectively, and is unlikely to fracture. A rupture during the candle’s burn can lead to calamitous outcomes! Some glassware might be too delicate. Opting for canning jars proves beneficial—they not only exhibit charm but also fulfill the prerequisites of heat resistance and optimal wax containment. Besides choosing suitable glass, adhering to certain precautions can avert glass breakage.

Firstly, always match the wick size with your candle. An inappropriate wick might generate excessive heat on the glass, potentially causing rupture. If uncertain about the wick size, refer to a “Wick Guide” that determines the ideal wick based on your container’s diameter and the wax type. Secondly, ensure the wick remains centered. An off-center wick can concentrate heat at a single point, leading to potential fractures in the glass.

Ceramic Considerations

When considering ceramics, it’s crucial to ensure the container isn’t porous, and capable of absorbing liquids. Ceramics are ideal candle containers but necessitate proper treatment to eliminate porosity. Porous, unglazed materials like clay pots could act as wicks, prompting flames to reach the pot’s edges, resulting in unexpectedly larger flames. Opt for non-absorbent options like ceramic plates and cups.

Metal Insights

Additionally, your container should be leak-proof, a seemingly obvious but crucial factor. Some metal tins possess seams on their sides or bottoms that could lead to leaks. Prior to pouring hot wax, inspect your metal tin thoroughly, perhaps even filling it with water to check for leaks.

When determining the safety of your container for candle making, ask yourself three pivotal questions: 1) Could it fracture? 2) Might it potentially ignite? 3) Is there a risk of leakage?

If uncertain or in doubt, consider purchasing candle containers from specialized suppliers. Reusing old candle jars is a fantastic option! To repurpose an old candle jar, try this hack: place it in the freezer for a day or more. The cold temperature causes the wax to contract and solidify, facilitating easier removal. Then, using a blunt butter knife, scoop out the wax residue. Remove any remaining soot stains with rubbing alcohol on a cotton pad. Follow up with a thorough wash using soap and water, allowing the jar to air dry.

However, regardless of your container choice, any vessel can pose risks if left unattended! Compliance with container selection guidelines doesn’t guarantee absolute safety; each candle should burn on a heat-resistant surface, far from curtains, plants, or any flammable items!
