Obsidian is the block a lava source hardens into when water reaches it.

Obtaining

Breaking

Obsidian drops itself only when mined with a diamond pickaxe. Mined with anything else, it drops nothing.

A pickaxe is not effective against obsidian, so even a diamond pickaxe takes 301 ticks, just over 15 seconds, to mine it.

Lava and water

A lava source with water beside it or above it hardens into obsidian.

Nether portals

A portal the game builds for an arriving player is framed in obsidian. Where the game has to carve out space for it, the portal also stands on an obsidian platform.

Usage

Obsidian is the frame of a Nether portal.

Behaviour

No explosion breaks obsidian, and a piston cannot push it.
