Molten Sulfer

The Metro was racing a CSX train this morning as we came into Silver Spring. The CSX train was a long string of tank cars marked "Molten Sulfer". What is molten sulfer used for? And why does it need to be molten for transport?

Add molten to the list of words that stop looking like words if you type them often enough.
