I'm glad you found my first round of experiments with the Vintaj inks helpful.
There is some air drying that happened on the raw clay. I didn't let the inks sit long enough on the clay to test how long it would take for them to dry completely (that is, past the sticky phase.)
Apparently if you use these inks on metal, it takes quite some time for the inks to completely dry to the touch. Using a heat gun was recommended on the package to speed drying on metal. That is part of the reason I took that approach when putting the inks on the raw clay.
I'm not familiar with the Adirondack white mixer, snowcap. I only have some Adirondack alcohol inks. The Vintaj inks are more like thin acrylic paints. There is a mixing ball in the bottle. That is why they reminded me of spray paints. The main ingredient is Ethylene Glycol Monobutyl Ether.
The mold I used is from a dried ear of corn. What was your guess?
