In addition to ease of use, shelf paper provides a slight escape route for air during firing and can reduce bubbles.
If you are able to get your work off the shelf paper without disturbing it you can spray it with hairspray (the cheap stuff like AquaNet or White Rain) to “re-bind” it so it doesn’t puff up dust when you put new work down on it to fire. Make sure to spray from above so that the spraying doesn’t blow the used shelf paper all over the place.
And always wear a mask – shelf paper without the binder is nasty stuff to be breathing in.
