Lava is a fluid block.

Obtaining[edit | edit source]

Lava cannot be obtained as an item, but can be retrieved with a bucket.

Natural generation[edit | edit source]

Lava occurs as magma in large pools deep underground, on levels 1 through 10, covering 8% of horizontal area. It can also occur as lava rivers from a single spring block, pouring down walls into pools.

Lava also spawns as lakes. They can be found at any elevation within any biome, can cause forest fires, and sometimes have floating chunks of stone or dirt above them, occasionally with vines or trees growing on the floating chunks (very small islands are sometimes in the center of a lava lake as well.) Lava lakes vary in size and depth, and the lakes will carve out a small air pocket area above them when generated, causing a ceiling underground or possible floating objects above ground. Lava generates in customized worlds with lava oceans set to yes.

2 blocks of lava can also be found in villages in blacksmiths' houses.

In the Nether, lava is extremely common, appearing more frequently than water in the Overworld. Seas of lava occur, with sea level at level 31, about a quarter of the total height of the Nether (as 63 is about a quarter the height of the Overworld). They extend down to about level 22 at the most. Lava also appears in single blocks inside the netherrack.

Usage[edit | edit source]

Burning[edit | edit source]

Fence posts are not burnt by lava above them.
What it looks like inside lava
  • Most entities will take 4 (Heart.svgHeart.svg) damage every half-second from being in contact with lava, and will also be set on fire. When in contact with Lava 300 Fireticks will be added instantly to the Firetimer of the entity/Player. For every further tick the Player is in contact with Lava, 2 Fireticks will be added to the Timer. For Example: 10 seconds in Lava will cause a total amount of 700 Fireticks (35 seconds) where the player burns (300 initially + 400 Fireticks for 200 ticks being in the Lava) or rather 500 Fireticks (25 seconds) left to burn when he leaves the Lava source.

Nether mobs (which are immune to fire) will take no damage, nor will players or mobs affected by a potion of fire resistance. If the victim touches water or rain falls on it, the fire will be extinguished, but the lava will continue to damage them directly.

  • TNT, bookshelves, leaves, carpets, wool, fences, coal blocks, vines, tall grass, wood, wood planks, wood slabs and wood stairs are flammable. If flammable blocks are close to lava they can catch on fire, although the mechanics are not the same as fire spreading. Non-flammable blocks are unaffected by this effect, and do not spread active fire.
  • The “embers” or “fireballs” which fly out of lava are purely decorative and do not cause fires or damage to entities. When it rains on lava, the rate at which the black "ember" particles appear increases dramatically.
  • A player in lava will last the following time, assuming the hunger bar is always full:
    • 3.5 seconds with full leather armor, no enchantments
    • 5 seconds with full gold armor, no enchantments
    • 5.5 seconds with full chain armor, no enchantments
    • 6.5 seconds with full iron armor, no enchantments
    • 14 seconds with full diamond armor, no enchantments

Fire spread[edit | edit source]

When a stationary lava block receives a block tick, the game will do one of the following at random (each has a 1/3 chance):

  • Choose one of the nine blocks above the lava block, and if it's an air block with a flammable block adjacent place fire there.
  • As above. Then if the chosen block is not solid and didn't catch fire this tick, choose one of the nine blocks above that and set fire there if it's air and has a flammable block adjacent.
  • Three times, choose a random block from the 8 surrounding the lava block at the same Y level plus the lava block itself. If the chosen block is flammable and has air above, place fire above.

Since catching fire depends on air blocks, even torches or lava itself can prevent a flammable block from catching fire.

Flow[edit | edit source]

See also: Fluids
Old flowing lava animation, still used in Pocket Edition.

Lava flows from "source blocks". Most streams or "lava-falls" come from a single source block, but lava lakes (including the "flood lava" in the bottom 10 layers) are composed entirely of source blocks. Only a source block can be captured with a bucket. Lava flows far more slowly than water, and sometimes sourceless lava flows will linger for a short time. In the Overworld, lava travels 3 blocks in any direction from a source block. Lava travels faster and further in the Nether than in the Overworld.

Lava which is flowing will destroy the following in its path: saplings, cobweb, tall grass, dead bush, wheat, flowers, mushrooms, snow on ground (but snow blocks are immune), lily pads, vines, levers, buttons, both types of torches, redstone, repeaters, and rails. Sugar canes hold back lava, but will disappear if the sugar cane's water source is destroyed by the lava.

Using a redstone wire, a one-block lava flow can be redirected by supplying power to the spring block, which will cause it to reset the flow towards the now-nearest terrain depression. This is further elaborated in this thread (only viewable when logged-in). It cannot, however, be reversed. This re-calculation is made because redstone wire when toggled changes the block from redstone(on), to redstone(off). Whenever a block updates on any side of lava, the lava re-calculates where to flow, but does not cut off its current direction of flow.

Lava and water[edit | edit source]

  • If lava flows on top of still or running water, it creates stone.
  • If lava flows horizontally into water, cobblestone is created.
  • If water flows horizontally into lava, a hiss and puff of smoke occur but nothing changes.
  • If water flows vertically into lava, cobblestone or a hiss may result.
  • If water flows into a lava source block then obsidian is created. The lava spring is destroyed in the process, so unlike cobblestone it is not continuous and renewable.
  • If vertically falling water touches a lava source block on any side obsidian is created - even if the water would not run into the lava's square.

Other[edit | edit source]

If there is lava flowing above a block, the lava seeps through.

Lava above a nontransparent block (does not include stairs, fences, and slabs) produces dripping particles on the underside of that block that can be seen within a certain distance with particles enabled. These droplets are purely aesthetic, functioning identically to their water counterparts, except water particles are slightly faster.

Lava can set off tripwires, because they break placed string. It will only trigger it once.

Arrows shot by the player will only catch fire if shot in flowing lava and not still lava.

Light source[edit | edit source]

Lava blocks emit a light level of 15.

Name

lava_bucket

Lava source blocks can be collected and replaced using a bucket, in much the same way as water can.

A lava bucket can be used as a very efficient fuel. It has the longest burning value of 1000 seconds, compared to 800 seconds for a coal block (a lava bucket smelts 100 items, a coal block smelts 80). After smelting starts an empty bucket remains, except sometimes on Minecraft: Xbox 360 Edition, the bucket disappears.

Lava spends most of its time as stationary, rather than 'flowing' – regardless of its level, or whether it contains a current downwards or to the side. When specifically triggered by a block update, lava will change to 'flowing', update its level, then change back to stationary. Lava springs are generated as flowing, and lava lakes are generated as stationary.

Data values[edit | edit source]

If bit 0x8 is set, this liquid is "falling" and only spreads downward. At this level, the lower bits are essentially ignored, since this block is then at its highest fluid level.

The lower three bits are the fluid block's level. 0x0 is the highest fluid level (not necessarily filling the block - this depends on the neighboring fluid blocks above each upper corner of the block). Data values increase as the fluid level of the block drops: 0x1 is next highest, 0x2 lower, on through 0x7, the lowest fluid level. Along a line on a flat plane, lava drops one level per meter in the nether and two everywhere else.

Block state[edit | edit source]

Name Value Description

 level
0 Lava source block.
1–7 Height of the lava, with 1 being highest.
Also represents the distance from a lava source or a falling lava.
In the End and Nether, only 2, 4 and 6 are used.
8–15 Falling lava.
This level is equal to 8 plus the level of the non-falling lava above it.
For instance a lava of level 2 will produce falling lava below it with level 10.
The distinction makes no difference in behavior.

History[edit | edit source]

Lava at the bottom of the map in Classic.
The same area as above, with water flooded in and bedrock exposed.
Pre-classic
rd-161348 The texture for lava can now be found within the game.
Classic
0.0.12a Added lava.
0.0.19a Lava-Pre Creative 0.0.19a.png The original texture was replaced. The old texture can still be found in the terrain.png file in the minecraft.jar
In Classic, lava spreads by duplicating itself to open horizontal and downwards squares like water. Lava is slower, though, and can be easily outrun. A quick player can block the flow of lava by building a dam. However, if the lava wave is large, a player may not be able to build fast enough. Also like water, lava slows down the player moving through it but it does so to a greater extent, and swimming through it causes greater damage. Lava is also more opaque than water and is harder to see through while you are submerged; you cannot see through lava from outside it. At the bottom of the map, lava can be found directly above bedrock in a different form, as it will trap the player and prevent the player from leaving unless water is let in and collides with it or if the player places a sand or gravel block, letting it drop into the lava. If water is let into the area where the lava is, the lava will form stone, allowing the stone block to be removed to expose bedrock underneath.
Lava's texture became animated.
0.24_06 Surface lava is now possible, however unlikely.
Lava now deals damage.
Indev
January 11, 2010 Lava now sets fire to flammable materials.
Infdev
June 17, 2010 Lava flows more realistically across surfaces but not as much as water does. Lava will flow for a total distance of 3 blocks "away" from the source block. Just like water, lava will flow in a single line towards the nearest terrain depression within four blocks. Items thrown into lava flows will disintegrate. All objects burn instantaneously when dropped into lava. Fired arrows will not disintegrate, but will appear to catch fire and can still be picked up. Magma is no longer present at the bottom of maps in this mode. Lava can melt ice and snow. Lava is luminous and a large lava flow is visible in the dark from quite a distance.
Alpha
1.0.6_03 Obsidian was readded after being removed in Indev.
1.1.0 Buckets of lava can be used to fuel a furnace for 100 smelts, consuming the lava and the bucket.
1.2.0 Added the Nether, with lots of lava everywhere. Lava also flows further in the Nether.
1.2.6 Using a lava bucket on chests and other blocks with GUI s no longer places the lava.
Lava lakes added.
Beta
1.8 When lava is touched by rain, it emits smoke.
Official release
1.0.0 ? When lava flows above a block, its underside now emits dripping particles.
Lava blocks now form stone when falling directly onto water source blocks.
Removed the ability to create an infinite lava source using a plus-sign shaped arrangement of blocks with four lava source blocks flowing into a central empty block.
1.2.1 12w05a Lava (as well as the embers that pop out of it) makes sounds. These sounds were in the game files for a long time but they had not played in-game.
1.3.1 12w15a Lava can be fired out of dispensers.
1.4.2 12w38a Flowing lava now has a constant sound.
1.5.1 ? There is "hidden lava" in the Nether, and lava flows much more quickly in the Nether.
13w02a The texture of lava is now accessible. Before, the texture was hidden in the code and not accessible by any normal basis.
Lava texture has been changed slightly.
1.7.2 13w37a Lava, which previously could be destroyed by a few blocks of TNT, can no longer be destroyed by explosions.
1.8 14w25a Block IDs 10 (flowing lava) and 11 (still lava) were removed from the /give command.
Now shows a lava bucket as the icon when lava is used as a layer in superflat.
Pocket Edition Alpha
0.3.3 Lava no longer creates fire, due to a game crashing spreading bug.
0.7.0 Lava now lights flammable blocks around it on fire.
Lava now has a flowing animation.
Added lava buckets.
0.7.4 Lava buckets can be used as fuel in a furnace.
0.9.0 build 1 Underground ponds of lava can now be found, making lava much more easy to obtain.
Added lava dripping particles.
Console Edition
TU1 Added lava.
TU9 Dispensers were given the ability to shoot out the liquids inside lava buckets. They could also suck up the liquids if activated again, but did not fill up the buckets with the liquid dropped due to a bug.
TU12 Lava (as well as the embers that pop out of it) makes sounds.

Trivia[edit | edit source]

  • A water source block placed 1 block away upwards diagonally (but not through corners) from a lava block will first flow in the direction of the lava, then other directions facing away from the lava. This happens because water physics treat the place that lava occupies as empty, and try to flow to it. Once the water turns the lava into obsidian, the water physics update to flow in all directions. (The same thing happens with lava flowing over water.)
  • Although lava is a liquid, it is not possible to drown in lava. This applies to all mobs.
  • When the player is in a bed, they cannot be damaged by lava.
  • In console versions, lava cannot be placed near the spawn point.
