The solid “rocks” are created through careful fermentation and drying, resulting in a highly concentrated dyestuff that carries both pigment power and cultural history.

Each batch is produced in small quantities by local artisans and is available only in limited supply. Once gone, it may not return, making this a unique opportunity to work with a truly exceptional indigo.

Active dye components: indigotin, indirubin

Shading Tips

• No mordant required: indigo bonds physically with the fiber
• Multiple dips: build depth from pale sky blue to midnight navy
• Overdye with weld or fustic: emerald and leaf greens
• Overdye with cochineal or madder: violets and purples
• Iron post-treatment: muted smokey blues and greys
