Cochineal Dyes?

[Bugbear]

Keep seeing "cochineal dyes" come up in history discussions.
Do you mean from the cactus bug, Dactylopius coccus, or is this historically referring to something else?
Just wondering.

Here is a wiki link on Cochineal dyes.

Isn't the commerce of rare dyes amazing? I read at the University in Dublin that the Book of Kells used lapis lazuli from Afghanistan, though a web search suggests that this probably isn't true. Nevertheless, commerce in natural pigments was (and still is) an important trade.

Yes, 'natural' coloring for red foods like little chocolates covered with colorful coating - melt in the mouth! Saw them used for dying of wool at Old Sturbridge Village in Massachusetts.

Ok, thanks, just wanted to make sure the "cochineal" in all the historical discussions on the forum meant the same thing; I'm never sure about anything historical.

Those are the Opuntia ficus-indica or "Indian Fig" cacti that are often used as a host.

If you had been around in the 1700s, Ted, you could have made a fortune raising cochineal bugs and selling them to dye uniform coats.

Thanks for posting that picture. I had almost forgotten what you look like.

As far as I know, piperdbh, there are none on my cacti. I know a lot of artists who would like to have a supply of the cochineal bugs, though, as well as several other natural dyes. Indigo comes to mind.

I had to email my sister because I didn't remember. Christmas 2008 I flew down to Cali, the airline lost my luggage, I was two weeks in California with my carry on. I bought some plain white tshirts, my sister the textile wizard had some cochineal bugs, and we got to work.

We used a grinder with a vertical plunger to grind up the bugs. I can't remember if I got mine at Williams Sonoma or Sur le table, neither are showing the unit as current product. Check Target for salt/ pepper mills before you buy.

With the the ground bugs in the bottom of a stock pot with 2 inches of water we brought the dye to a simmer and submerged one of my new plain white shirts for 20 minutes or so.

Two years later (100% cotton) it looks like this. It was never "red" or "purple", but once upon a time it was pretty dark for pink.

That is unusual if you are using a mordant before the dying ... what mordant did you use? You typically heat the mordant and cloth in solution of just below boiling (~200 degrees F) for about an hour and then let it cool. And THEN do the dying.

Aurorasilk.com goes over the process here : Dying Process

It typically gives a beautiful scarlet color that lasts forever when processed with an Alum mordant.

Guess you could make cochineal red hose that way.
