Calcium Hydroxide – Hydrated Lime for Natural Dyeing
This natural calcium hydroxide (also known as hydrated lime, slaked lime, or calx) is a versatile, high-quality product derived from limestone and water. Valued in both traditional crafts and ecological applications, it is especially important in natural dyeing for preparing indigo vats and supporting resist techniques.
✨ Ideal for Natural Dyeing:
Indigo vats: Raises pH and supports the reduction process, allowing indigo to dissolve fully.
Organic indigo dye baths: Works with ingredients like iron or fructose syrup (e.g. the 1-3-2 vat inspired by Michel Garcia).
Fabric pre-soak: Deepens and enriches indigo shades when textiles are pre-soaked in lime water.
Nori paste (Japanese resist): Helps rice starch swell, giving body to the paste and extending its shelf life.
A must-have for natural dyers working with indigo, and a useful addition to any natural dye studio.
