Yes, you can refire them to a glaze again. It works best when you warm the
pieces to be glazed slightly, like to 250* or so. It helps the pot's
surface accept the glaze better.
Usually that "look" no pots means that more glaze was needed. That too much
of the glaze was absorbed by the pot instead of laying on the surface. The
term we use is refractory. Adding more fluxes to the glaze or altering the
fluxes in the glaze (flux is the melting point of different chemicals.)
will help. This is the kind of thing that potters struggle all their lives
with. It is the art of the glaze.
good luck
