Testing Soy Wax Candles – Evaluating Scent, Appearance and the “Burn Test”

Starting a journey into candle making is all about diving deep into the craft of turning simple soy wax into container candles that not only smell amazing but also scream quality. Candle making is pretty much like mixing art with science—you’ve got to get your hands dirty, pay attention to the tiny details, and really get to know your wax, wicks, fragrances, and containers inside out. Considering how many different elements can change the game, figuring out a solid way to tell which candles are the top of the class becomes super important.

This guide is like your friendly map through the tricky terrain of candle making, zeroing in on what makes a candle truly special, way beyond what’s trending. We’re specifically tailoring our criteria for a budding candle-making business operator – but you can use most of the criteria even if you aren’t planning to sell your candles.

For those who are looking to start a candle making business, success oftentimes comes down to your ability to build a strong brand. Building a brand that’s known for top-notch candles means nailing the perfect mix of soy wax, scent, and style, and making sure every candle that comes out is something to be proud of.

Evaluating the quality of soy wax candles involves considering several critical factors that impact both the performance and the appeal of the candles. Here’s a comprehensive set of criteria you can use to assess your soy wax container candles:

1. Burn Quality

  • Even Melt Pool: The candle should melt evenly across the surface, creating a melt pool that reaches the edges of the container without tunneling. An ideal melt pool depth is typically around 1/4 to 1/2 inch.
  • Burn Time: Assess how long your candle burns relative to its size. A longer burn time can be a selling point, indicating efficiency and value.
  • Wick Behavior: The wick should burn cleanly without producing excessive soot or smoke. It should remain centered and not mushroom excessively.

2. Scent Throw

  • Cold Throw: The aroma of the candle when it is not lit. It should be noticeable and pleasant without being overpowering.
  • Hot Throw: The strength and distribution of the fragrance when the candle is lit. It should fill the intended space without being too faint or too overwhelming.

3. Appearance and Presentation

  • Surface Quality: The top surface of the candle should be smooth and free of blemishes, such as sinkholes or frosting, once it has cooled and set.
  • Container Compatibility: The container should not only be aesthetically pleasing but also functional, capable of withstanding the heat of the candle without cracking or discoloration.
  • Consistency: All candles in a batch should look uniform in appearance and performance.

4. Fragrance Oil Compatibility

  • Oil-Wax Interaction: The fragrance oil should be well incorporated into the wax, without separation or sweating.
  • Fragrance Stability: The scent should remain consistent throughout the life of the candle, without fading over time.

5. Safety

  • Proper Wick Size: Ensuring the wick is the correct size for the candle’s diameter to prevent high flames or soot.
  • Container Safety: The container should be safe for candle use, meaning it can handle the heat without breaking and is large enough to contain the melt pool.

6. Environmental and Health Considerations

  • Clean Burning: The candle should be free from harmful chemicals and pollutants. Soy wax is already a good choice in this regard.
  • Sustainability: Consider the environmental impact of your materials, including whether the soy wax, fragrance oils, and wick materials are sustainably sourced.

Practical Steps for Evaluation

  • Create a Testing Protocol: Set up a consistent method for testing each candle variant under the same conditions. This includes burn time, room size for scent throw tests, and initial candle weight.
  • Document Results: Keep detailed notes on each test, including any anomalies. Photos can help document issues like tunneling, sooting, or frosting.
  • Feedback from Testers: If possible, get feedback from a small group of testers to provide insights into consumer preferences, especially regarding scent throw and burn quality.

By systematically evaluating your candles based on these criteria, you can identify the best formulations for your small business. To that end, we just wrote a post with a specific candle testing protocol that you might want to use to keep yourself structured and organized during your formulation and testing phase.

Remember, achieving perfection in all areas is challenging, so prioritize the factors most important to your brand and target market.
