What substance is the most common ingredient in a snowflake?

Background
Many people think a snowflake is just frozen water. In reality, every snowflake needs a tiny solid core in order to form at all. Usually this is a tiny grain of dust or a pollen grain. The water freezes onto that and then builds the beautiful shape.
