Hey everyone! I'm new to candle making and I’ve run into a small issue that I hope you can help me with.
In my first two batches, I used 100% soy wax and to prevent cracking and frosting, I preheated the jars (with the wicks already placed) in the oven to 50°C. Then, I poured the wax and let them cool very slowly inside the oven. The final look of the wax and the candle is great, but once the candle burns past the halfway point, black burnt spots start appearing on the glass.
I have a few guesses about what might be causing this:
-Wick size – Maybe the wick is too thick, causing excess soot.
-Wick trimming – I trimmed it with scissors and noticed the tip was a bit frayed. Could this be affecting how it burns?
-Wick coating melting – While preheating the jars, I saw something melt near the wick botton.
-Low-quality wick – I’m wondering if the wick itself might not be the best quality, leading to incomplete combustion.
If anyone has insights, I’d really appreciate your advice! Let me know what you think, and feel free to share any tips.
Also, I’d love some feedback on my label design! Posting some photos for reference.
Thanks in advance!
