Obsidian Guide: Make Portals and Mine It Correctly
Quick answer: The modern Java item ID is minecraft:obsidian. Obsidian forms when water meets a lava source block and must be mined with a diamond or netherite pickaxe to be collected.
Create or find obsidian safely
Water flowing onto a lava source block creates obsidian. The word source matters: lava flow behaves differently, so test the terrain carefully instead of assuming every lava block will give the same result. Natural pools and ruined portal areas can also provide opportunities to collect it.
Bring the correct pickaxe before you begin. Breaking obsidian with an unsuitable tool wastes time and does not give the block item.
Choose the next project before mining a large supply
A first obsidian supply commonly goes toward a Nether portal, an enchanting table, or an ender chest. Those projects need different related materials, so decide which one is next and gather the linked items at the same time.
If you only need the block for a command build, use the current Java give command above. Use the setblock and fill tools when the goal is placing obsidian in the world rather than adding it to an inventory.
