Mordant - Hydrated Lime

Lime (Calcium Hydroxide 85%) is a versatile alkaline agent used across a range of textile dyeing processes, including indigo dyeing, natural dye preparation and pH adjustment. It plays a key role in creating the alkaline conditions needed for certain dyes to develop properly and for pigments to become soluble.

Commonly used in indigo vats, lime helps maintain the correct pH balance, allowing the dye to remain active and produce consistent, strong colour. It is also used in other natural dye processes where careful control of alkalinity is required. This fine-grade powder dissolves easily in water, forming a stable solution that can be used reliably in both studio and workshop settings. Its consistent performance makes it a dependable choice for dyers working with traditional or modern natural dye techniques.
