can you sandblast the objects and recoat with the same glaze, then refire
to the same temp?

Seeing as the glaze bubbled the first time, it might well do it again, so
I would be careful with that.

not necessarily. if the gases (or the components of the minerals that
produce the gases) that caused the bubbles are gone, then only the newly
added glaze would cause bubbles, if any.

Also, "just" grinding the pock marks down and then adding a little glaze
to those areas has worked for me before.
