Making Black Walnut Stain
It is Strongly Recommended that you wear Rubber Gloves, Eye Protection, and old clothing when handling Black Walnut Hulls or the resulting Stain Mixture. And anything that comes in contact with the Hulls or stain may be indelibly marked.
After removing the Walnuts,
(1) - put three quarts of Hulls and one quart of Rain Water
in a Metal Bucket or Cook Pot.
(2) - Mash the Hulls with the end of a hammer handle
in the bottom of the Metal container.
(3) - Let them soak ten hours or more
(4) - Bring them to simmer over medium heat.
(5) - Simmer them for 30 minutes.
(6) - Allow them to cool.
(7) - Repeat step (2).
(8) - Allow them to drain through a Wire Strainer or Colander.
(9) - Then squeeze the remaining liquid from the hulls.
(This will be the most concentrated stain liquid)
(10) - Now strain the liquid through a Coffee Filter.
(11) - Store it in a plastic jug.
This stain works best if it is preheated to about 110F.
Wear Rubber Gloves when handling Black Walnut Hulls,
or your hands will become an unsightly brown.
White Eggs can be dipped in it to color them brown.
Boards can be stained with a brush or rag. I prefer a rag.
Apply it sparingly, and wipe off the excess. Let the board dry.
If you desire darker stain, apply subsequent coats.
Always allow the board to dry between coats,
as the shade will change upon drying.
Sand the boards and apply your favorite Sealer and Finish.
For Fox Traps you may want to double the Hulls in the recipe.
This creates a thicker mixture.
Traps are submerged in this mixture after step (7).
Keep them in the mixture about twelve hours, stirring occasionally.
Then remove them by the chain with rubber gloves.
Hang them on a tree limb and spray off the residue with a garden hose.
Allow them to air-dry.
The hulls contain a Toxin called Juglone. It is also contained in the roots, bark, and leaves of the black walnut tree. It remains in the soil years after the tree is cut down. It is thought to be harmful to Horses. It is KNOWN to be harmful to garden plants, especially Tomatoes which become wilted as though blighted. It is best to distance your garden from your Black Walnut trees.
Some think the Toxin will dissipate during composting. But it may be wise to limit the amount of Black Walnut sawdust, leaves, chips, and hulls in your Compost.
