Ink

= Ink (Harry Potter) =
Ink is a liquid containing dye(s) or natural colouring(s). When it is used, it produces images and texts on various surfaces and media.
==History==
Ink was used in conjunction with quills to write on parchments by wizards and witches in the wizarding world in place of the pens and pencils in the Muggle world. There were several types of inks, such as Azul Marino ink, various forms and types of Invisible Ink, Disappearing Ink, glow-in-the-dark ink, acidic ink, Self-Correcting Ink, Colour-Change Ink and Everlasting Ink. Harry Potter seemed to prefer a scarlet-coloured ink.The feathers of the Augurey repelled ink, thus making them useless as quills.Gilderoy Lockhart used Lilac Ink, his favourite colour. Harry used this when he was helping Lockhart answer his fan mails as a detention in 1992.As part of its abilities as a Horcrux, Tom Riddle's diary could absorb ink, and could interpret any messages written in it when it absorbed them. It could also respond to these messages in ink, though it would reabsorb the ink used after a few moments. When it was destroyed by Harry Potter in 1993, it leaked a large quantity of ink, similarly to how a human would bleed.Peeves would often shoot ink pellets at Hogwarts students. This would usually only stop with the interruption of angry ghosts or teachers.
==Behind the scenes==
*In "The Black Lake" level of , as Harry Potter and Cedric Diggory swim through underwater tunnels, the Giant Squid cuts through the rock and releases ink, forcing Harry and Cedric to use Lumos Solem in order to find their way to the end of the tunnels.
*Even though it was not on the list of required equipment that was sent out each year, it is presumed that students would have had to buy ink and parchment (enough to last them until the next holidays).
*Though Harry Potter uses scarlet-coloured ink in the novels, he is seen to use inks of other colours, such as blue or black, in the films.
