      Deep within the Earth’s mantle, the magma below Kilauea (on Hawaii) is about 1500oC, that is about the temperature that iron melts. By the time this magma reaches the storage chamber under the volcano (it takes about 8 years) it has cooled to about 1200 oC. Once the lava cools to about 1000oC it starts to go solid!
