Vintage Jug ‘Lava’

This jug was manufactured around 1960, presumably in Germany. The jug has different colors such as brown, white, black and red. The colors white, black and red seem to flow over the jug like lava. At the bottom there is an (unclear) mark: LW? 72?

Interior advice
This jug fits in both a classic and modern interior. You can place it for example on a TV cabinet, (side) table, windowsill or in a bookcase. You can also place (silk or dry) flowers in it.
