Onion skins

Allium cepa, pelure d’oignon, Zwiebelschale, cáscara de cebolla, craiceann oinniún

Yet another example of never having learnt everyday words in the language class. While Caecilius erat in horto and coquus erat in culina, we never actually learnt what coquus was cooking. Probably meat as we learnt the Latin vocab for “pest” and “scoundrel”, which he shouted at the dog as it ran out of the kitchen. I don’t think la famille Bertillon ever cooked with onions, and Herr Wasistseinname probably didn’t buy them at the Frankfurter Messe. The fact that we all know what it’s like to cry onion tears really needed to be taken into account. Thank heavens I learnt Spanish without a text book! Dame un kilo de cebollas, por favor. Ya!

And so to the dyeing…  During one workshop the onion skins produced a dark red. As the skins were a little pinkish, I thought perhaps they were either from shallots (nah… too big…) or a new type of “pink” onion that had appeared in the gardening mags and in the supermarket. Haven’t seen them since, so I guess they weren’t popular or suitably different to what we already have. During a subsequent workshop we used brown onion skins and ended up with the same deep red. Interesting.

With my latest experiment, I used 100% WoF brown onion skins. Didn’t get the deep red, but pleasing results anyway:

onions

As usual, 1, 3, 5 7 no mordant; 2, 4, 6, 8 15% WoF A/Cot; 3 & 4 alkaline modifier, 5 & 6 acid modifier, 7 & 8 iron modifier. The photo has picked up a little too much contrast in the plys: squint and imagine there are no white bits. But what about light-fastness? Apparently, low. I read in one source (can’t remember which one), that onion dye fades to a “pleasing shade”, and on another source (French, but that’s all I can remember – with all due respect to the author) that subsequent dyebaths will improve fastness. I have another 16 mini-skeins to test, along with these samples, fastness after the first, second and third dyebaths. More on that later. Even though we use a lots of onions, 40g of skins takes a lot of curries!
