Log

A log or stem is a naturally occurring block found in trees or huge fungi, primarily used to create planks. It comes in eight types: oak, spruce, birch, jungle, acacia, dark oak, crimson and warped.

A stripped log or stripped stem is a variant obtained by using an axe on a log or a stem respectively.

Breaking
Logs and stems can be broken by hand, but using an axe speeds up the process. Logs drop themselves when broken with any tool.

Trees
Oak, spruce, birch, jungle, acacia, and dark oak logs generate naturally as part of trees.

Huge fungi
Crimson and warped stems generate naturally as part of huge fungi.

Structures



 * Oak logs generate as part of houses in plains villages, and as supporting beams of swamp huts.
 * Stripped oak logs generate in plains villages.




 * Spruce logs generate as part of houses in taiga and snowy villages.
 * Stripped spruce logs generate in snowy tundra villages.




 * Acacia logs generate as part of houses in savanna villages.
 * Stripped acacia logs generate in savanna villages.




 * Dark oak logs can generate in pillager outposts as a pile of logs, and as part of watchtowers. They are also generated in woodland mansions in the walls and borders


 * Mixed


 * Oak, spruce, and dark oak logs generate as masts in shipwrecks.
 * Stripped oak, birch, spruce, acacia, jungle, and dark oak logs generate as masts in shipwrecks.
 * Oak and dark oak logs blocks generate as part of woodland mansions.

Logs and stems
Trees can also be grown using saplings and huge fungi can also be grown using small fungi.

Stripped logs and stems
an axe on a log or stem turns it into a stripped log or a stripped stem, which act the same as regular logs.

Further crafting
The following table presents the amount of logs or stems needed to produce an even multiple of a given item with no waste left over, and the quantity produced (Planks and Charcoal are assumed to be crafted from logs rather than wood blocks):

Fuel
Logs, but not stems, can be used as a fuel in furnaces, smelting 1.5 items per block.

Data values
$$, oak, spruce, birch, and jungle log and wood have the ID name  and are further defined by their block data or block state. Acacia and dark oak log and wood blocks have the ID name  and are further defined by their block data or block state.

Note that when a log is placed, it changes its facing parameters, placing in the direction relative to the block it is placed on.

Logs consider only the axis; a sideways log placed while facing north does not have a top texture rotated 180 degrees from a log placed south.

ID




Block data
$$, log uses the following data values:


 * Log


 * Log 2


 * Stripped Log

Trivia

 * Dark oak and acacia logs previously shared or currently do share a block ID separate from the old logs, called log2, because all the other data values on the previous log block were occupied by rotated variants (red sandstone slabs suffered a similar fate). There are still 8 remaining data values on the block that cannot be obtained.
 * Even if stems or their plank variants cannot be used as fuel or made into charcoal, the player can bypass this by crafting them into crafting tables or sticks, which can be used as a fuel.
