Gel

Info
Gel is a common and important item in Terraria. It is typically dropped by Slimes and occasionally zombies. It is used to craft a wide range of things, though the most important are Torches, Lesser Healing Potions and the Slime Crown. Gel can be farmed by using a Slime Statue connected to a 1/4 second timer, or during a Slime Rain. The former is more efficient, whereas the latter produces gel faster, though has a time limit.

Ge can also be used as ammunition in Flamethrowers, and it can make throwable items become sticky. Gel dropped from a Pinky slime will be labelled as Pink Gel, and instead of making items sticky, it will make them bouncy. Both gel and Pink gel can be made into solid blocks using the Solidifier, and normal gel blocks can then be used again at the Solidifier to make various items of gel furniture.
