No Ordinary-Invisible Ink

Invisible Ink was a type of magical ink that transfigured anything written in it to become invisible. Text written in invisible ink could be rendered visible again in two ways, either by using a Revealer, or the charm Aparecium.
==History==
Hermione Granger thought the contents of Tom Riddle's diary might be written in invisible ink and tried "Aparecium" to reveal them, but it had no effect.
==Behind the scenes==
*With it being a form of transfiguration, invisible ink may have actually vanished the text written in it.
