This depends: an ink may be a true sollution or a colloidal solution, or a suspension.
The chemical compound found in most inks is called carbon black, which consists of carbon molecules in a colloidal suspension. Each specific type of ink may contain additional components such as colorants, solvents, and binders.
The original inks were a colloidal suspension with the fine ink pigments suspended in water along with animal hide glue to make the final product stick to the writing surface. Newer inks, as in printers, are mostly not real inks, but dies. (more than one dye)
The original black ink used earliest in history was a suspension of carbon in water. Modern inks contain pigment, pH modifiers, humectants, polymeric resins, wetting agents, biocides, and thickeners.
It's a suspension!
Suspend, pendulum, append, depend, expend, impending, suspend, suspension. (Root word Pen/Pend)
Toothpaste is not a simple suspension but a Colloid suspension. A Colloid suspension is a suspension that has microscopic particles suspended in another substance.
You need really fine iron powder; a fine file and somthing out of iron you can file. Then a liquid to keep the iron in suspension; it should dry (evaporate) but not too quickly- water will work if you use your ink right away- if you wait the iron will rust and rust is not as magnetic as pure iron...
A suspension has large particles that settle out on standing.
soluble ink is ink that is soluble
ink is expelled from their ink sac
