Log

Wood (previously known as Log) is a naturally occurring block fundamental to the crafting of many blocks and tools in the game. They have a skin resembling bark on the four side faces, and a crosscut face on top and bottom. Only the normal oak logs are available in chunks generated before the Beta 1.2 update and all previous versions, whilst pine and birch will generate in newer chunks. Wood is greatly abundant in naturally-generated maps, as it is used as the foundation for trees. Wood can be chopped by hand, but using an Axe consumes less time. Wood is also flammable.

Of the current wood types, birch is the rarest type. They are often used to make plants, trees and wooden cabins. In Survival Test and early Indev (0.31), wood blocks drop 3 - 5 Wooden Planks when mined. In later Indev, Infdev, Alpha, and Beta, mining a wood block will drop a wood block instead. This allows the use of wood as a building material and is craftable into planks.

Wood's only crafting use is to be made into four Wooden Planks. In addition, wood can be smelted in a Furnace to make Charcoal as a substitute for Coal.

There are currently four varieties of wood. One is the normal wood (Oak); another is Birch, which is a lighter color and has dark spots over it; a third type, Spruce, resembles Oak but is dark in color and grows in colder biomes; the fourth type, Jungle, resembles Oak wood with bark aligned horizontally, and solely occurs in Jungle Biomes. Wood from different types of trees will produce different colors of Wooden Planks when crafted and will not stack in the inventory. Birch trees have slightly duller colored leaves than regular trees, pine trees have pine needles, and jungle leaves are leafy with fruit-like shapes.

The fourth type of wood solely occurs in Jungle Biomes, and comprises trees exclusive to them. The tallest trees have this type of wood in 2x2 dimensions instead of the normal 1x1, however 1x1 jungle trees can still be found.

Occurrence
Besides forming trees, wooden blocks can also be found in NPC Villages where they form the edges of farms and are also used in the corners and roofs of a few small huts. Wood is a renewable resource, and can be grown again using saplings.

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

Texture data values
When the data value is greater than 16, it appears to wrap back around when giving the item, so, for example, 17:53 is spruce facing East/West. You can get these by using /give (username) 17 1 (data value) on a world with cheats on. Note that when you place them, they act like normal wood blocks, placing the direction you face.

Trivia

 * In real life, the number of rings on the inside of a tree counts the age of the tree. If one counts the rings of a wood block, the sum is four years.
 * It is advisable to use Wooden Planks as fuel instead of wood, as they share the same burn time. However, it is advisable, if you do have wood, to smelt the wood and use charcoal as fuel.
 * Some oak trees and birch trees have the same structure: 5 or 6 wood blocks and a pattern of leaves that stays the same for both regular oak and regular birch trees.
 * Picking up a block of Wood, typically one of the first things a player does in a world, gives them the "Getting Wood" achievement.
 * Chopping wood using a tool with the Silk Touch enchantment causes it to drop a regular (oak) wood block, regardless of the type of wood chopped. This is a bug.
 * Although wood is usually considered renewable, there is the chance for a tree grown from a sapling to drop 0 saplings, so if you begin with a set number of trees, it is potentially possible that all of them and their planted saplings will drop 0 saplings, depleting the resource; in practice, this is almost impossible because the probability of a tree dropping 0 saplings is low.
 * When a world that has a jungle biome in it is opened in 1.1 instead of 1.2.1 or further, the wood and leaf types will be changed into oak wood and leaves.
 * Wood can be found above layer 128.
