I’m preparing to make dye from black walnut hulls. Some recipies call for soaking the hulls in ammonia for several days, but Eugene Landon’s Finish Line article in FWW 168, p. 121 says he makes the dye by soaking the hulls in water for several months. Is anything gain or lost (other than time and odor) by using the ammonia?

I made some a few years ago by putting them in a pot on top of my shop heater, One of those things with kerosene that sits on the floor. I added water to it when it dried out and stewed the stuff for a couple of weeks, then strained it and bottled it. worked fine...
I think the purpose of the ammonia is to keep mold from growing in it. I soak mine in water, strain it and then add some ammonia to it along with a few drops of dishwashing detergent. Then whenever I need to use some I hold my nose, open the lid and splash a little more ammonia in. If you use lemon scented ammonia it helps with the smell...a little bit.
Can you accelerate the process by boiling the husks?
I don't know. Probably it couldn't hurt, boil or steam them. But it's pretty fast. I mixed up regular grocery store ammonia with a bunch of green to brown walnuts and 2 weeks later I had a really strong dye. It will be absolutely great for dying walnut sapwood.

Don't think boiling continuously would do much, but chopping them coarsely will speed it up, puts more hull in contact with your solvent.
The ammonia may act as a mordant or catalyst, I'm not sure of the chemistry.
The one time I used walnut hulls I chopped them coarsely, placed them in a stainless steel pot, covered with distilled water (65¢/gal at Kroger at the time), brought them to a boil for about ten minutes then poured them into a hot Mason jar, sealed the jar with a band and lid -- mostly to ensure killing off any bugs/microbes/fungi. Left the jar in the basement for about three months, filtered through multiple layers of old tee shirt into a clean jar.
As I recall, I used it on some poplar and some maple, worked fairly well.
Good luck.Leon Jester, Roanoke VA
