I think it is the new type. Uncommon.

Seems there is going to be a common and uncommon variant of each element combination.

So iron is common, slag is uncommon. It is not rare, which seems to cover opposite elements and has special breeding requirements. It is not limited, for example bone, with restricted breeding dates. It is not special, for example, sun, moon, gold. We almost need a new naming standard to keep track of the special types or properties that they require,
