What is molten matriel

Everybody always uses it to mean some kind of liquid that's hot and smoking,

like glowing smoking molten lava creeping down the sides of a volcano, or red

hot molten steel pouring out of the furnace in a steel mill in a shower of sparks.

But I think technically it just means melted ... water is molten ice.

Molten material is a hot liquid, such as lava, that is formed from the melting of different types of rock.
