You can let it cool and reduce it again if it isn't encased but you probably won't get as nice a reduction on the second go round.

It is the opposite of over-reducing the glass. Some glass tolerates a lot of reduction, some like the gentlest reduction and if you go past that, you will get a dull opaque cloudy result. You can erase/restrike the over-reduction. Take the bead back to transparent, cool and try gently reducing again.
