Coal vs Slag What''s the difference? WikiDiff

As nouns the difference between coal and slag is that coal is (uncountable) a black rock formed from prehistoric plant remains, composed largely of carbon and burned as a fuel while slag is waste material from a coal mine. As verbs the difference between coal and slag is that coal is to take on a supply of coal (usually of steam ships) while slag is to produce slag.
