Choosing the Right Candle Container
At emc2 Creations, the safety starts with the container. Not all vessels are created equal, and the material a candle is poured into is critical for a safe burn.
The National Candle Association's (NCA) safety protocols emphasize using heat-resistant, non-flammable vessels to prevent fires in your home. Using vessels not made for candles can be risky as they may become too hot and burst, creating a fire hazard.
Safest Choices
πͺ Glass Jars: I use high-quality glass jars that are manufactured for candle making guaranteeing the glass is safe to endure the high, sustained temperatures of a burning wax pool.
πͺ¨ Hydro-Stone: I use vessels hand poured from Hydro-Stone. Since this material is naturally porous, I ensure it is completely sealed with a candle-safe sealant to prevent wax penetration.
Proceed With Caution
π Metal Vessels (Like Tins): Many skilled candlemakers use tins successfully. However, metal is an excellent heat conductor, and tins can potentially heat up too quickly and excessively and may damage the surface underneath. For this reason, I only use tins for wickless candles, where no direct flame is involved.
Containers to Avoid
πͺ΅ Wood Vessels: These are a significant fire hazard. Wood is flammable, and when combined with a hot wax pool, the entire container can catch fire.
π« Unique/Unverified Vessels: I am often asked to make candles into unique items, like antique teacups. The answer is strictly no, for your safety. A container must be specifically made and rigorously tested to withstand candle heat. Testing several identical items for safety isn't possible with a single, unique vessel.
The Final Safety Rules
Even with the safest containers, these final rules enhance your safety:
π΅ Heat-Safe Surface: Always place your burning candle on a heat-safe surface away from drafts and flammable objects.
π₯ When to Stop Burning: Dispose of the candle once it reaches Β½β to ΒΎβ of wax remains at the bottom. This step ensures the flame's heat never reaches and compromises the very bottom of the container, preventing the jar from dangerously overheating or cracking.
