So excited to have found this forum, appears to have very experienced candlemakers. I have been making container candles for just a short time. While trying to gain more information I have read that people allow their wax to cool to 150 for example than add their FO because otherwise it burns off. Is this true? What are your suggestions? I'm afraid doing that will cause issues with adhering to containers, but if this does preserve the scent I would like to know. I have been pouring at the recommended temp around 175 to 180, they cure perfectly, but if I can get more scent throw lowering the wax temperature before adding FO, I will try that. I'm hoping you'll have suggestions.
