Half-bakery is a 14-cell still life made up of two loaves. It is half of a bakery, and the term bi-loaf refers to it most commonly.
Half-bakery reaction
There is a remarkable reaction where a glider collides with the half-bakery, displacing it by (3,6) and generating another glider in the same direction as the input. The only other known reactions of this type involve stable reflectors, which have a displacement of (0,0), alongside a constellation of three blocks.
In May 2004 Ivan Fomichev found an over-unity reaction generating 90-degree output gliders with pairs of these reactions. This is the key of half-baked knightship and parallel HBK.

Half-bakery can also act as a turner in various other collisions.[1]
Commonness
Half-bakery is the eleventh most common still life in Achim Flammenkamp's census, being less common than barge but more common than mango.[2] It is also the fifteenth most common object on Adam P. Goucher's Catagolue.[3]
