|Transparency||Yes (only when flowing)|
Lava is a fluid block which harms the player by every second. It also sets on fire any nearby flammable blocks. On a flat surface, it can flow up to a distance of eight blocks. Lava sources, which can only be obtained in creative mode or using the
/giveme command, are stackable. Lava buckets, on the other hand, cannot be stacked.
Lava first appeared in version 0.2.20110922.
