Log

"I'd estimate that about 95 percent of my Minecraft worlds begin with me collecting a single block of Oak Wood. It's the mother-block - the block from which everything else in the game develops. Without collecting wood, it's almost impossible to play Minecraft. Seriously, try playing Minecraft without wood. It'll be about as much fun as playing blindfolded, or with me screaming "USE WOOD YOU FOOL!" into your ear the entire time."

- Duncan Geere

Log is a naturally occurring block found in trees, primarily used to create planks. It comes in six species: oak, spruce, birch, jungle, acacia, and dark oak.

Stripped log is a variant obtained by using an axe on a log.

Obtaining
Log can be broken by hand, but using an axe will speed up the process.

Natural generation
Oak log blocks generate as part of houses in plains villages, acacia log in case of a savanna village and spruce log in case of a taiga, snowy tundra, and snowy taiga village. Oak logs generate as supporting beams of witch huts. Oak and dark oak logs blocks generate as part of woodland mansions.

Spruce logs can be found in taiga and snowy taiga village house chests.

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.

Dark oak logs can generate as a pile of logs and in pillager outpost watchtowers.

Stripped spruce logs generate in snowy tundra villages.

Stripped oak logs generate in plains villages.

Stripped acacia logs generate in savanna villages.

Trees
Log blocks of all six types generate naturally as part of trees. Trees can also be grown using saplings.

Stripped logs
an axe on log will turn it into a stripped log.

Further crafting
The following table presents the amount of log needed to produce an even multiple of a given item with no waste left over, and the quantity produced:

Fuel
Wood logs can be used as a fuel in furnaces, smelting 1.5 items per block. It is far more efficient to craft each log into four wood planks: each plank will burn as long as the log would have, for a total of 6 items.

Smelting log into charcoal is slightly better: each charcoal will smelt 8 items, but the charcoal itself needs to be smelted. The net items smelted therefore is 7. Also, the increased need to load and unload items will usually result in some loss of smelting time.

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

Block data
In Bedrock Edition, 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.
