An Alchemy Station is a crafting station that is used to craft additional items. The alchemy station is mainly used to craft potions although it is used to craft some items, such as Vile Powder. To create an alchemy station you need to place a Bottle, Mug or Pink Vase on top of a Wooden Table, Work Bench, Dresser, Tinkerer's Workshop, or Wood Platform. If an alchemy station is created with a Work Bench, then it functions as both an alchemy station and a Work Bench.

Note that when you look at the Guide (NPC) for a potion, he tells you Bottle and not alchemy station, as it just needs to be a bottle on any possible item.
