Kitchen dyes: Dyeing with pomegranate

Stoffe faerben mit Granatapfel

Pomegranate as a dye? There are quite a few fugitive plants found in our kitchens. That are so inviting especially for first dye experiments, like red cabbage or beet root – yet not colourfast. But pomegranate peels are a trustworthy and traditional source of dye.

Ich färbe nur ungern mit Essbarem – aber das Schöne ist ja, die Schale vom Granatapfel wird natürlich nicht gegessen, sondern landet auf dem Kompost. Oder im Färbetopf! Das ist also auch unter dem ‘Zero Waste’-Aspekt eine schöne Färberpflanze.

Pomegranate trees (Punica granatumare not native where I live. Their home is West/Central Asia but they have been cultivated in the Mediterranean for a very long time. Today they are grown pretty much around the globe wherever climate allows for it. The trees can stand light frost. In Germany they need some protection to overwinter, unless your garden is in an especially mild growing location.

Pomegranate peels as dye plants have a long history in the Mediterranean and West Asia, and can yield pale beige, bright or golden yellow, ocher and greys to blacks. There are some very old instructions for dyeing with pomegranate peels, dating to the neo-Babylonian period (626 to 539 BC), more on that can be found in Dominique Cardon’s Natural Dyes.

Bark and roots were also used for dyeing. In addition, they were also used medicinally. Humans and pomegranate trees have a long and multifaceted history.

Zero waste: Compost colours, even in winter

Because I was curious about dyeing with the peels, I once asked at a juice stall at the weekly market if I could have some pomegranate peels. And after some explanations I was allowed to get some in my bag. You will most likely find a vendor offering orange and pomegranate juice, too! Just kindly ask them for the peels. It is also one of the few dye plants that can be found here in winter, although not in the wild.

Drying pomegranate peels for dyeing

Recipes usually refer to dried pomegranate peels. To thatend I scrape the skins thoroughly with a spoon to remove flesh and seeds, and then dry them with as little pulp as possible. So if you eat one pomegranate from time to time and only have a few peels and not a whole bag like I do, that's no problem either. Simply dry your peels one at a time and keep collecting until you have enough. Dried dye plants are easy to store. Best protected from sunlight, but airy so nothing gets damp and moldy. I use brown paper bags and cardboard boxes to store them.

Tannin rich dye plant

Pomegranate peels are a special dye plant because they contain a high proportion of tannins. In many plants that dye yellow, flavonoids are responsible for this, but not here.
Tannins have a dual function in dyeing. Not only as a dye, but often they are also used in the pre-mordanting process. They can deepen colors and make them more colourfast.
And in pomegranate peels they are the reason why you can also use it to dye unmordanted fibers and still get fast colours: a rather delicate yellow or beige-yellow. With aluminum mordants it turns a stronger golden yellow and with iron the tannins react to shades of gray to black.

Dyeing with pomegranate peels

Most recipes I saw recommend equal weight of fiber and dyestuff.
Ich habe auch meist mit getrockneter Schale gefärbt, auch mal mit einem höheren %-Verhältnis – die Farben wurden nicht viel intensiver, eher etwas schmutziger, fand ich. Wenn die Schalen zwar trocken, aber noch recht “neu” waren, habe ich etwas reinere Gelbtöne bekommen. Bei Schalen, die schon einige Jahre getrocknet waren, fand ich die Töne weniger klar und leuchtend, etwas mehr Richtung Ocker. Falls dir das auch aufgefallen ist, oder du das gar nicht bestätigen kannst, schreib mir gern einen Kommentar dazu. Es interessiert mich sehr, ob andere auch diese Beobachtung gemacht haben!

For comparison I also dyed with fresh peels that had only dried overnight. The colors were more delicate, a beautiful clear yellow. (When using fresh plants for dyeing, remember to use a higher WOF % than with dry plants. They contain a lot of water, which makes them heavier.)

For dyeing, break or crush the dry peel into smaller pieces. I like to soak them overnight before gently heating them the next day and then dyeing as usual.
The author Eberhard Prinz (recommended herealso mentions that flowers and peels of unripe fruit dye red tones. I could not test that so far, but maybe you have that opportunity.

I was also interested whether a cold extraction would shift colours. To test this I cut up fresh peels and soaked them in water for a few days. This dye bath looked indeed redder than the hot extraction. But from all the fibers I dyed, only the wool yarn looked different, a bit more reddish. Of course, the hot extraction is quicker and yields more dye in the process.

Reading further about pomegranates

Im Buch ‘Natural Dyes. Sources, Tradition, Technology and Science’ von Dominique Cardon habe ich jetzt nochmal zum Granatapfel nachgeschlagen. Darin sind dem Baum drei Seiten gewidmet. Wenn dich Geschichte von Färberpflanzen, Färbemethoden und das Chemische “hinter den Kulissen” vom Färben interessiert, ist das ein wirklich spannendes Buch. Ich lese es sehr langsam (es hat über 700 Seiten), und benutze es ansonsten als Nachschlagewerk. Das Original ist Französisch, und ins Englische wurde es zwar übersetzt, soweit ich weiß aber nicht ins Deutsche. Wenn du einen vergleichbaren Wälzer suchst, aber auf Deutsch, vielleicht ist dann Helmut Schweppe’s ‘Handbuch der Naturfarbstoffe’ (see here) is what you're looking for.

Vor allem aber bin ich in der Bibliographie von Cardon’s Buch auf einen weiteren Titel gestoßen, der mich neugierig macht. Der Granatapfel hat eine reiche Kulturgeschichte, ist unter anderem Symbol für Fruchtbarkeit und das Leben, und nun steht ‘Der Granatapfel. Symbol des Lebens in der alten Welt’ von Friedrich Muthmann, 1982, auf meiner Leseliste.

Have you dyed with pomegranate yet? Or do you maybe have another pomegranate reading suggestion for me?
