Ask that son of yours to secure a bag of sanding dust from a floor finisher in the area.
The fine dust seals off the body from the air, and does not mark the glaze in any way save for color.
I use it to turn the clay in my Tea work very dark grey to reduce the contrast between clay and body.
Cheers, Hank in Eugene
