>>12049616>these companies dump millions of dollars into research.Yeah, I'm not trying to make it as good using a hundred different chemicals. The concept sounds simple enough but I don't want to just try it without getting some info first because it'll probably clog. I have no recipe, no ratios, don't know the appropiate thickeners or gellificators to use etc.
>I've never heard of "homebrew ink" before.Yeah it's a thing but not gel ink specifically, I find nothing about it.
>is it as simple as embedding fountain pen ink in some sort of containment gel?This is what wikipedia says:
>Compared to other inks, gel ink has higher viscosity, which supports a higher proportion of pigments in the medium. The pigments are typically copper phthalocyanine and iron oxides, and the gel is made up of water and biopolymers, such as xanthan gum and tragacanth gum, as well as some types of polyacrylate thickeners.
