- If I remember my chemistry right, fluorine gas can be stored in copper
- containers. The fluorine reacts with the cooper at first, but the
- resulting fluoride forms a protective layer that is immune to any
- further attack by fluorine. The effect is similar to the oxide layer
- that protects aluminium.
