At what stage?

Also...I have been carving some platters that I have made and am wondering what the best way to glaze it would be as I am afraid that the carving will be filled in with glaze. I want the carving to be highlighted and in no way covered as well as very contrasted from the rest of the ware.
I apologize for the newbie questions but it seems in ceramics that the answers to the obvious are the hardest to find

Decals are applied after a glaze firing . . . then the item is refired to cone 016 or so to fuse the decal into the glaze.
To keep the carving from being glazed over, apply some wax to the carving . . . the wax will repel the glaze. Depending on design, location you may have the glaze run over the carving. You'll just have to experiement to find the right solution for what you are doing.

Different approach than bciske. It is just how I developed for what I am trying to do.
If I am doing image transfer, I do it "soft" leather hard.

You can apply underglaze to unfired work but you lose some of the ability to correct mistakes ..e.g. you can just wash the underglaze off of bisque ware.
You can fire between underglaze applications to seal the work in place so the next step doesn't ruin it ... but, the wrong glaze could still make it bleed or run. Some underglaze colors are more prone to bleeding on the edges.
You can use wax resist or latex resist to protect your carved designs from glaze, but the wrong glaze could still run there during firing.
Every single way of doing it is favored by someone and disliked by someone else. So, I would strongly recommend you make a bunch of test tiles in an L shape and carve some designs on the long side ... then do some tests until you come up with a look you like. That will be your 'right' answer.
