Genista Extract
Source: Dyer’s Broom (Genista tinctoria)
Genista extract is a bright, water-soluble natural dye derived from the flowering tops of Genista tinctoria, commonly known as Dyer’s Broom. This traditional European dye plant yields clean, sunny yellows that perform beautifully on both protein and cellulose fibres.
The extract dissolves easily in water, making it suitable for immersion dyeing, textile printing, surface design and ink making.
Main Components:
• Flavonoids (primarily luteolin)
• Isoflavones
Suggested Quantities (WOF – Weight of Fabric):
• Light Shades: Use 2–4% WOF
• Medium Shades: Use 5–8% WOF
• Brighter/Deeper Yellows: Use 8–10% WOF or layer with weld or alum-tannin mordants
Uses:
• Natural Dyeing of Protein & Cellulose Fibres: Produces vibrant, clear yellows
• Printing & Surface Design: Use in thickened pastes or binder systems
• Ink & Paint Making: Suitable for water-based dye binders or lake pigment preparation
The Plant:
Dyer’s Broom (Genista tinctoria) is a native European shrub historically used in medieval dyehouses for its strong yellow hues. Harvested just before flowering, the tops are processed using a low-impact extraction method to produce a dye suitable for modern natural textile applications.
Light Fastness:
Medium
Note:
This is a soluble dye extract, not a pigment. It is fully water-soluble and ideal for immersion dyeing or printing with gum or starch binders.
