A magma block is a light-emitting block found underwater in the Overworld, and more abundantly in the Nether. It deals burning damage while stood on, which can be prevented by sneaking. Underwater magma blocks produce bubble columns that pull entities downward and provide air.

Magma blocks can be mined using any pickaxe. If mined without a pickaxe, they drop nothing.

In the Overworld, magma blocks generate at the bottom of water aquifers in underwater magma in clusters of 1–8 blocks, and in sulfur springs in clusters of 1–3 blocks.

Magma blocks also generate as a part of ocean ruins, ruined portals that are not in cold biomes, and the eruption room found in trial chambers.

Magma blocks generate in the Nether in the form of ore features. In Java Edition, it attempts to generate 4 times per chunk in sizes of 0–160, from altitudes Y=27 to Y=36 in all biomes. It can only replace netherrack. In Bedrock Edition, it attempts to generate 9 times per chunk in sizes of 0–106, from altitudes Y=23 to Y=36 in all biomes. It can replace netherrack and blackstone.

Magma blocks generate as part of deltas in basalt deltas biomes, replacing some of the lava.

Magma blocks also generate as a part of hoglin stable and treasure room bastion remnants, as well as all ruined portals in this dimension.

Magma blocks damage most living entities standing on top of them, even if underwater, dealing 1HP👁 💔
of fire damage every tick, which in practice is reduced to once every half-second with damage immunity. Walking into the side of a magma block doesn't cause damage. Damage from magma blocks does not reduce durability in netherite armor. Because magma blocks deal fire damage, it can be reduced by armor, the Resistance effect, and Protection/Fire Protection enchantments, and can be completely negated by the Fire Resistance effect. Unlike other sources of fire damage, sneaking and the Frost Walker enchantment can also grant immunity to damage from magma blocks.

Any mobs immune to fire damage cannot take damage from magma blocks. However, a few mobs like shulkers cannot take magma block damage despite not having natural immunity to fire.

Magma blocks do not set mobs or players on fire and thus do not cook the animals that they kill, nor do they destroy items.

Blocks that are the height of a trapdoor or lower (such as snow layers, carpets, repeaters, or comparators) do not prevent a magma block from damaging mobs and players above it.^[1][2] However, a sunken boat on top of the magma block prevents damage.

There are a few specific death messages associated with magma blocks. If a player or named pet is killed simply from standing on the block, the death message displayed in the chat is: "[player] discovered the floor was lava". If a player or named pet was attacked and knocked back to their death onto magma blocks, the message is: "[player] walked into danger zone due to [player/mob]".

Magma blocks emit a light level of 3. They do not melt ice or snow.

Magma blocks emit smoke particles under rainfall, much like lava.

Making walls out of magma blocks prevents spiders from climbing them.‌^{[BE only]}

Mobs try to avoid walking over magma blocks but still walk over them if no other path is found. Most mobs do not spawn on magma blocks (exceptions are magma cubes, zombified piglins, ghasts, and squid).

When a magma block's top is set on fire, the fire burns indefinitely, similar to netherrack.

When a water source is directly above a magma block, a whirlpool bubble column is created, going down from the highest source block. Anything encountering the bubble column is pulled down, including items, boats, players, and mobs.

A player can restore breath underwater by entering a magma block's bubble column.

When placed above a magma block and below a water source with a height of 1 to 4 blocks, potent sulfur may occasionally erupt. A full cycle occurs every 300 to 1200 game ticks (15 to 60 seconds), while the eruption phase lasts between 20 and 100 game ticks (1 to 5 seconds).

When a block of potent sulfur is placed, two random values are assigned to it based on the position of the block in the world: a dormant value (between 15 and 30) and an eruption value (between 1 and 2). The intervals between the dormant state and the eruption state depend on the height of the water column above the potent sulfur and these two values:

• dormant phase duration (in seconds): ;
• eruption phase duration (in seconds): .

Geysers generate naturally on the surface as part of sulfur springs due to them featuring magma blocks. The sulfur pools within sulfur caves do not feature magma blocks underneath their potent sulfur, and thus geysers cannot be found naturally in sulfur caves.

• Geologists only call melted rock magma when it's very deep underground, beyond accessibility. Any melt closer to the surface is called lava.

• A magma block is used as Steve's Up-Smash attack in the crossover fighting game Super Smash Bros. Ultimate.
