Can you refire cone 10 crystalline glazes if they didn't turn out well?

Yes, and you could try a mix of zinc & silica mixed with gum applied
to the already fired glaze in small "dots" to try seeding crystals.

I occasionally refire crystalline pots, and this is my rule of thumb:
If the firing was too hot-- that is, the glaze is all shiny with no
crystals, and probably ran off the pot, there is no hope of improvement
from refiring. If it is rather rough in appearance and grainy, refiring
may work.
