My previous results with a fresh pot were in the pink and purple range.
This dye/tannin was definitely worth the expense. I’ve had a pot sitting for two weeks in the back room, where it’s quite cold in the winter. No mold grew, no funny smells, no questionable sludge, so i decided to throw a few odd bits in to see what colours i’d end up with. (I know there’s still a lot of colour in the pot, as an experienced eye can tell when a pot is exhausted and when there’s still dye stuff left.)
A few scrappy bits of sheer silk chiffon from 8 years ago (the original hollyhock had completely faded: no mordant!), i love the purple/pink cast to this brown. The cotton lace was a surprise as well. (Note none of these were premordanted, in this case because QR is also a tannin, which can be a mordant. Normally i would have premordanted, even old scraps.)
The gold in the photo below, to the right, was an errant piece of previously ecoprinted POLYESTER, that had snuck into the pot long ago. GOLD? All right!
But that deep reddish brown on the osage (yellow) silk velvet–OOOOOOOOOOOOO!
So, the Quebracho Rojo has gone from giving striking pinks and purples to rich warm browns., money well spent.
