About a month ago we went to a local art shop which is the home base of the amazing water-colour paints (https://stonegroundpaint.com), and as we got talking about colors, paints and dyes, the owner, Eric, brought out a container of dried cochineal and gave me some to take home. So yesterday I finally got to it and cooked up some dye with alum and cream or tartar (as suggested by some fabric dyeing recipes). The pink you see on these eggs is that cochineal dye.
The other coral-like reddish orange is coreopsis extract with alum on top of the fist cochineal. The brown is the same cochineal-coreopsis sequence finished with a dip in iron water.
I will have to play more with the next batches of the dye (I only used about a teaspoon of bugs, which I then ground not very finely), I will likely use more bugs next time (to make the color more concentrated), I’ll grind them better, and will start with no mordants, and add cautiously.
For the first experiment with the whole bugs, I think this is not bad. I have tried cochineal extract before but didn’t have a lot of it, so I used it in combination with madder.
The next few months I will be experimenting more with cochineal, both the whole bugs and the extract. My parents gave me for Christmas a gift certificate to the Maiwa online store, so I’ll order some cochineal from them.
