What is the easiest way to get a few magma blocks?

Check ruined portals. They generate in the Overworld, need no combat or potions, and usually have several magma blocks around the frame.

What is the fastest way to get hundreds of magma blocks?

Mine the veins in the Nether's basalt deltas around Y 27–36. No other source comes close for bulk collection.

Can you get lava from a magma block?

No. Magma blocks are not a lava source and can't be converted into one. For renewable lava you'll need a dripstone lava farm instead.

How do you stand on a magma block without taking damage?

Sneak while walking on it, or wear boots enchanted with Frost Walker. Otherwise it deals steady fire-style damage.

Magma blocks are one of those resources you ignore for weeks and then suddenly need by the stack — for a downward bubble elevator, a mob farm killing floor, or a gold farm build. The good news is they generate in several places across two dimensions. The trick is picking the source that matches how many you actually need.

All the Sources at a Glance

Method	Where to Look	Best For
Nether veins	Basalt deltas; also bastion treasure rooms and hoglin stables	Hundreds of blocks
Ocean floors	Seabeds and underwater caves	Medium amounts, no Nether trip
Ocean ruins	Built into some ruin structures	A small bonus while looting
Ruined portals	Scattered around the portal frame	A quick handful
Crafting	4 magma cream in a square	One-off needs when cream is spare

Mining the Nether Veins

This is the bulk method and it isn't close. Magma generates in large veins through the Nether, and the basalt deltas are saturated with it — vast grey fields patched with magma around the lava lakes. Aim for roughly Y 27 to Y 36 as you dig and you'll cut through vein after vein. Bastion remnants hide extra magma in their treasure rooms and hoglin stables if you're raiding one anyway.

Prepare properly: the deltas are crawling with magma cubes and the footing is treacherous. Fire resistance potions earn their keep here, and a good pickaxe with decent armour makes the trip routine instead of risky.

The Overworld Options

Not ready for the Nether? Dive instead. Magma blocks generate on ocean floors and in underwater caves, and they announce themselves: the bubble columns they produce are visible from a long way off. Bring water breathing and sweep the seabed ravines. Ocean ruins sometimes have magma built into their walls — only a few blocks, but free. Easiest of all, ruined portals almost always spawn with a handful of magma blocks around the frame, alongside the gold block and chest loot. For a single elevator, one or two portals usually cover you.

Crafting (the Slow Way)

Four magma cream arranged in a square on a crafting table makes one magma block. Since the cream comes from magma cubes — which keep splitting into smaller, angrier cubes as you fight them near lava — this is a lot of combat for one block. Craft only when you need a couple and already have cream sitting in a chest.

What Magma Blocks Do

Bubble elevators: water above a magma block becomes a whirlpool that drags players, mobs and items downward — the standard "down" shaft.
Mob farm floors: mobs standing on magma take steady damage, and unlike fire, magma doesn't burn the drops. Items survive to be collected by hoppers.
Traps and defence: a magma perimeter hidden under carpet quietly discourages both mobs and other players.
Geysers: paired with the right blocks and a water column, magma powers decorative geysers for builds.

One warning: standing on magma burns. Sneaking, or wearing Frost Walker boots, lets you cross it safely.
