How to craft it
Furnacea display case that reacts to what is inside
It hangs from the underside of a block instead of sitting on a surface, which makes it the natural way to use ceiling space in a trophy room. Drop an item in and the liquid takes on that item's rarity color, so a wall of them reads at a glance: a row of yellow flasks is a row of endgame gear, a row of gray ones is junk. That sorting cue is something an Item Frame cannot give you.
placing it
Cycle up and down before you place it to choose between three glass shapes, since you cannot change the shape afterwards without taking the whole thing back down. Getting the contents out again is the same key that put them in, or a pickaxe swing if you would rather collect the flask too.
trivia
It comes from a crossover with Dead Cells, where flasks like it sit in the same sort of wall alcove. The liquid glows in the dark once placed.
