Lessons

What you are working with

  1. Perfumery Material Types for Beginners

    Essential oils, absolutes, concretes, resinoids, CO2 extracts, tinctures and isolates: what each one is, how it behaves on your bench, and which to start with.

    20 min · Exercise: Classify what you already own

  2. What Are Aroma Chemicals? A First Guide

    Aroma chemicals are odorous molecules used as perfumery ingredients, some isolated from nature and many synthesized. Learn what to expect from your first few.

    15 min · Exercise: Meet three aroma chemicals on paper

  3. Read a Material's CAS Number and SDS

    A guided first reading of a safety data sheet and CAS number for a perfumery material: where to look, what to record, and what these documents leave out.

    20 min · Exercise: Read one real SDS

Bench technique

  1. Safe Handling of Perfumery Materials at Home

    A beginner routine for handling aroma chemicals and essential oils safely at home: ventilation, gloves, flammable alcohol, spills, labels and what to avoid.

    15 min · Exercise: Audit your workspace

  2. Your First Weighing Practice

    A beginner's practice session with a perfumery scale: how to choose one, tare it, add drop by drop, and measure how repeatable your weighing really is.

    15 min · Exercise: Hit 1.00 g five times, using water

  3. Perfume Dilution Basics: Make Your First 10%

    Make your first 10% dilution by weight, label it properly, and step down to 1% and below. Includes a free calculator, worked examples and common errors.

Keeping a working library

  1. How to Store Perfume Materials

    Keep perfume materials fresh and safe: light, heat, air and containers, why oxidized terpenes matter, how to log your stock, and how to judge an old bottle.

    15 min · Exercise: Set up storage and a stock log

  2. Build a Training Material Library

    Choose, buy, dilute and document a small training library of perfume materials: which ones teach the most, how many you need, and how to finish Stage A.

    20 min · Exercise: The Stage A project: your documented library
