Bars

Bars are crafting materials generally crafted from mined ores at a Furnace. Crafting most ore-related items requires that raw ores are first crafted into bars.

There are currently 23 different bar types. Obtaining most of these only requires their respective ores as crafting ingredients. Hellstone, Spectre, and Shroomite Bars are exceptions that require a secondary material in addition. Hallowed Bars are not crafted but are instead dropped by the mechanical bosses. Some bars may also be obtained randomly from crates.

Notes

Bars can be placed like furniture, take up a space of one tile, and can be stacked on top of each other. When placed in this manner, they can be used just like platforms, to stand on and drop down from, and furniture can be placed on the top (torches also to the sides).

Bars cannot be placed without another block underneath them; this makes it impossible to build a house made of bars without the aid of other blocks. This mechanic makes breaking bars similar to cutting down trees, where breaking the bottom bar in a stack will break all bars above it.

The only way to make placed bars "float" would be to abuse the fact that chests with items inside cannot be destroyed. Using bars as support under such a chest would mean they cannot be destroyed until the chest is emptied. This allows them to float in-air without any supporting blocks. Note: The duplication glitch with bars and a chest was patched long ago in 1.2

Trivia

Hallowed Bars are the only bars to not require an ore to be made.

Although a single bar is consumed when it is placed, the tile sprite appears to be 3 or possible 4 bars stacked on top of each other.
