Our extract is sourced directly from 100% waste walnut hulls and therefore has limited seasonal availability to winter.
This Black Walnut Paste is 7% solids content that is concentrated into an easy-to-use paste from eastern American black walnut (Juglans nigra) 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.
We now have an improved formula for cotton. 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.
We source our black walnuts from local hulling stations around Tennessee and Kentucky. Anyone in the area can bring in their walnuts to be hulled. We take what would normally be agricultural waste.
Since this is a natural product, it is inherently variable and unique, adding to the beauty of plant-based color.
