Our extract is sourced directly from 100% waste walnut hulls and therefore has limited seasonal availability to winter. We will not restock until December 2021. If Black Walnut Paste is placed alongside other items in an order, we will cover shipping of the paste within the United States, once it has become available.
This Black Walnut Paste is concentrated into an easy-to-use paste from the Rubia tinctorum tree’s walnut hulls. As a substantive dye, walnut ranges from warm taupes and dark browns to mustard yellows and mauve pinks without the need of a mordant.
Our improved formula yields higher and more saturated dye content and has been specially formulated for natural dyers. Black walnut contains juglone and tannins to produce saturated colors and provides extra depth in combination with other dyes. Our product turns fabric darker when post-mordanted with Iron, while other “natural walnut browns” cannot offer the same results.
