How to Blend Fragrance Oils Effectively

Fragrance oils shape the scent profile of every candle. This guide explains how blending works and how to choose the right oils for strong hot throw and balanced aromas.

Fragrance oils for candle making stay stable, offer versatility, and support complex scent combinations. They outperform essential oils in heat stability and scent projection. This guide walks you through blending methods, fragrance notes, ratios, and sourcing reliable oils.

What Are Fragrance Oils?
