Perfume Blending Kit

The scent's three phases. Top notes (citrus, herbs) are light and volatile — they evaporate first (the first 15 minutes). Heart notes (florals, spices) are the core (the next few hours). Base notes (woods, resins, musks) are heavy and linger (the dry-down, hours to days). A balanced perfume has all three; the journey from top to base is the perfume's arc.

Essential oils are natural plant extracts (complex, subtle, variable); fragrance oils are synthetic/aroma-chemical (consistent, wider range, often more "literal"). Natural perfumery uses essential oils and absolutes; modern perfumery uses fragrance oils (and a blend of both). Natural is the artisan path; fragrance oils are the accessible and consistent one.

A balanced blend of two-to-five notes that reads as a single new scent — the building block of a perfume (a perfume is several accords layered). Crafting an accord (a jasmine-rose-sandalwood that reads as "floral-wood") is the perfumer's core skill. The accord, aged a week to integrate, becomes a module you combine into the full perfume.

Freshly blended oils are disjointed — the components have not integrated. A week (or more) of aging lets the molecules marry into a smooth, unified scent. A new blend smells "raw"; an aged blend smells "designed." Aging is the perfumer's patience — the same as a cured soap or a conditioned mead. Age the accord, then the full perfume.
