Half-bakery is a still life that is made up of two loaves (and makes up half of a bakery). When the term bi-loaf is used, this pattern is its most common meaning.
There is a remarkable reaction where a glider collides with the bi-loaf, displacing it by (3,6) and generating another glider in the same direction as the incident glider. The only other known reactions of this type involve stable reflectors, which have a displacement of (0,0), alongside a constellation of three blocks. This displacement reaction has enabled the construction of half-baked knightships:

It can also act as a one-time glider reflector in various other collisions.
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.[1] It is also the fifteenth most common object on Adam P. Goucher's Catagolue.[2]
