- Meet the beetles: Cochineal dyeing

I need to say up front that tiny cochineal beetles did lose their lives in the pursuit of this latest natural dye experiment. Encased in waxy white webbing and tiny in size, it was easy to pretend that I wasn't doing anything untoward ... especially since their habitation was ultimately destined to be burned ...


But it did feel a little creepy. However, putting aside my moral scruples I read up on how a local blogger gathers cochineal beetles and then made up my own way (after all, when have I ever followed a recipe?)

Taking a vintage knife with a flexible blade and a bit of linen, I went out and started to scrape little bits of white off of prickly pear (Opuntia) cactus pads. The beetles were well protected, usually hunkered down on the underside of a cactus spine, presumably to deter birds from eating them.

As I repeatedly wiped the blade off on the linen, the potency of cochineal as a dyestuff became abundantly obvious. Unsure as to how much would be needed, I filled one side of the cloth, folded it over on itself and was halfway to filling the next side when a snake and I scared the heck out of each other. 

Don't ask me what kind of snake it was ... a sorta big snake is all I know. Big enough to convince me that I had collected quite enough cochineal beetles, thank you very much ...


Having read that cochineal is particularly sensitive to mineral content, I decided to use distilled rather than tap water and heated it to a simmer in the hot pot I used for tea at my last job. Fortunately, the hot pot is no longer needed for that purpose.

I dropped the beetle smeared cloth into the water and color happened within seconds ...


An hour later, I had to fish out the cloth for a look as it was no longer visible in the darkened brew ...


Still, having watched the Dharma Trading dyeing tutorials I decided to give it time to steep overnight (with thanks to KINDRED SPIRIT Dee Mallon for pointing the Dharma Trading info out to me) . 

Next I pulled together four batches of cotton and linen cloth scraps for pre-mordanting ...


putting them into canning jars with 1 tsp. of food grade alum and 1 cup of boiling distilled water ...


The plan is to do four jars with ...
  • Alum alone
  • Alum with cream of tartar
  • Alum with fresh lemon juice
  • Alum with steel wire
So tomorrow morning I will warm up the bug juice, strain out the solids, and pour it into the canning jars in equal measures.

Then I will cap the jars and wait. 

How long will I wait? I haven't a clue. Suggestions anyone?
