Bad batch of chemicals?
I prepped 3 Jacquard cyanotype kits (all at the same time, in the same way I always do). And 2 of the kits gave me a dark green coating to my textile, the third was the normal yellow-ish tone. You can see in the picture the contrast between the green and the yellow. I exposed the textiles, and there was basically no contrast, the whites were more blue/purple. Any clue what caused this? A bad batch of chemistry?
I prepped the chemicals separately 24 hours before mixing, etc.
