How to Make Obsidian in Infinite Craft
Checked in the game in October 2026
Obsidian is volcanic glass, and the game builds it from Lava twice over. Earth and Fire make Lava, Water cools some of it into Stone, and pouring fresh Lava onto that Stone produces Obsidian. Lava is used in two places, so drag a second copy from your list for the final merge.
Quick answer
Lava+Stone=Obsidian
Combine Lava and Stone to get Obsidian.
