I mentioned the pasty nature of the drain-safe ink I was mixing earlier so many times that I decided to go find some paste and mix pigments into that. It wasn't easy to find paste these days, so I mixed food coloring with glue and flour. It worked. I didn't like the pastel coloring that the flour added, but I was able to squeeze it through the screen with my "2X4 squeegee"(TM) and I left the shirt out to dry. The idea here is that glue has the consistency of the types of inks that I use for screen printing. Also glue claims to be Non-toxic and Safe since it is most commonly consumed by children as a dietary suppliment and is most likely more nutritous than the foods available in the free-food program (if they still have that). We'll see how this washes tomorrow.
I remember a Borden product for coating decks that was supposedly made of biodegradable/milk products. Basically water-based carriers like honey and glue mix well with food dyes and oil based greasy products don't unless they are diluted first. However the oil based products withstand drying while stored in a concentrated environment like a bowl and therefore have a long shelf life. The goal here is to maximize pot-life and maintain a thick viscosity with bright pigments in a bio-degradable mixture. The problem is that the pot-life and drying potential are opposite effects. Which explains the popularity of plastisol inks since they have an almost eternal pot-life and controllable drying time with heat, as well as, a bullet-proof opacity if necessary.
