knob popping and dinnerware discoloration

What's the best way to attach knobs so they don't detach in the bisque?
I used to score and slip them, but 1/4 or more would pop. Lately I've
been carving a hollow in the knob, slipping it on the lid, then making a
pinhole in the lid from the other side to allow air out of the enclosed
space. Then the myth dispeller in a recent CM said you can dispense with
scoring and use a slip with vinegar. Tried that and am back to high
losses.
Also: Any solutions to this: When I make dinner plates (cone 10
oxidation), I use a gloss white glaze. Even though its glossy, it's not
mirror smooth. When people cut meat on the plate, stainless steel marks
remain. Same thing with mixing bowls and steel spoons. Is there any
way to clean it off? I'm guessing the only way to avoid it would be a
glassy smooth surface, or having the glaze match the hardness of steel,
instead of exceeding it.

Brad I trim a little stump on the lids to attach my nob and have very few
come off. I score the top and attach a ball of soft clay and then throw
the nob.
I don't know of any glaze that isn't going to mark. Matt and semi-matt
are usually worse, but a little scrubbing cleanser will take it off when
you wash.
