A magma flow is a special type of map tile found at the bottom of the magma sea, forming the floor above semi-molten rock. Items dropped onto a magma flow from above will disappear (the same as when dropped into a chasm), but creatures can safely walk on the tiles as long as no magma is present. Magma pools and volcanoes refill by spawning magma directly above magma flow tiles, however, so they tend not to remain safely walkable for long.
Similar to items dropped on a magma flow, natural walls and floors dropped by a cave-in will disappear. This happens in the same tick as a cave-in, and the magma flow will consume the entire column, no matter how high it is.
If the magma is cleared away (or if a large area is excavated beneath stone directly above semi-molten rock), the magma flow tiles will animate and sparkle just as the original magma flow did in versions 0.23.130.23a and earlier.
