#2444: MagmaMould

In many places volcanoes exude a flow of liquid rock almost continously.

Today’s invention offers a way for local communities to exploit this, by offering mementos to visiting pyrophiles.


A mould could be created (by local craftsmen) and attached to a tractor using a long spar made of high melting point steel.

As the tractor drives the mould into the magma, the trapped gas escapes through a vent in the top.

The tractor withdraws and the rock within the mould gradually cools, allowing stone sculptures to be extracted for later sale.
