Abstract: Coated glass articles for a glass-ceramic ceramming process including a parting agent coated on a surface of the glass article. The parting agent coating can comprise an aqueous dispersion comprising amorphous silicon dioxide agglomerate particles and a dispersant. The parting agent coating can be dried to forming a parting layer for glass articles in a glass stack for a ceramming process that transforms the glass articles into glass-ceramic articles.
