Lava flows from "source blocks". Most streams or "lava-falls" come from a single source block, but lava lakes (including the "flood lava" in the bottom 10 layers) are composed entirely of source blocks. Only a source block can be captured with a bucket. Lava flows far more slowly than water, and sometimes sourceless lava flows will linger for a short time. In the Overworld, lava travels 3 blocks in any direction from a source block. Lava travels faster and further in the Nether than in the Overworld .

Lava which is flowing will destroy the following in its path: saplings, cobweb, tall grass, dead bush, wheat, flowers, mushrooms, snow on ground (but snow blocks are immune), lily pads, vines, levers, buttons, both types of torches, redstone, repeaters, end rods, and rails. Sugar canes hold back lava, but will disappear if the sugar cane’s water source is destroyed by the lava.

Using a redstone wire, a one-block lava flow can be redirected by supplying power to the spring block, which will cause it to reset the flow towards the now-nearest terrain depression. This is further elaborated in this thread. It cannot, however, be reversed. This re-calculation is made because redstone wire when toggled changes the block from redstone(on), to redstone(off). Whenever a block updates on any side of lava, the lava re-calculates where to flow, but does not cut off its current direction of flow.

A lava bucket can be used as a very efficient fuel. It has the longest burning value of 1000 seconds, compared to 800 seconds for a coal block (a lava bucket smelts 100 items, and a coal block smelts 80). After smelting starts, the lava bucket turns into an empty bucket.

Lava spends most of its time as stationary, rather than ‘flowing’ – regardless of its level, or whether it contains a current downwards or to the side. When specifically triggered by a block update, lava will change to ‘flowing’, update its level, then change back to stationary. Lava springs are generated as flowing, and lava lakes are generated as stationary.

The lower three bits are the fluid block’s level. 0x0 is the highest fluid level (not necessarily filling the block – this depends on the neighboring fluid blocks above each upper corner of the block). Data values increase as the fluid level of the block drops: 0x1 is next highest, 0x2 lower, on through 0x7, the lowest fluid level. Along a line on a flat plane, lava drops one level per meter in the nether and two everywhere else.

In Classic, lava spreads by duplicating itself to open horizontal and downwards squares like water. Lava is slower, though, and can be easily outrun. A quick player can block the flow of lava by building a dam. However, if the lava wave is large, a player may not be able to build fast enough. Also like water, lava slows down the player moving through it but it does so to a greater extent, and swimming through it causes greater damage. Lava is also more opaque than water and is harder to see through while you are submerged; you cannot see through lava from outside it. At the bottom of the map, lava can be found directly above bedrock in a different form, as it will trap the player and prevent the player from leaving unless water is let in and collides with it or if the player places a sand or gravel block, letting it drop into the lava. If water is let into the area where the lava is, the lava will form stone, allowing the stone block to be removed to expose bedrock underneath.

Lava flows more realistically across surfaces but not as much as water does. Lava will flow for a total distance of 3 blocks "away" from the source block. Just like water, lava will flow in a single line towards the nearest terrain depression within four blocks. Items thrown into lava flows will disintegrate. All objects burn instantaneously when dropped into lava. Fired arrows will not disintegrate, but will appear to catch fire and can still be picked up. Magma is no longer present at the bottom of maps in this mode. Lava can melt ice and snow. Lava is luminous and a large lava flow is visible in the dark from quite a distance.

• A water source block placed 1 block away upwards diagonally (but not through corners) from a lava block will first flow in the direction of the lava, then other directions facing away from the lava. This happens because water physics treat the place that lava occupies as empty, and try to flow to it. Once the water turns the lava into obsidian, the water physics update to flow in all directions. (The same thing happens with lava flowing over water.)
