If you love layers, coat your pieces with Cover-Coat Opaque Underglazes! Applied directly to soft-fired bisque or bisque, these underglazes provide solid coverage over even the darkest colours, and are perfect for airbrushing and brushwork.
Cover-Coats are nontoxic clay and water based opaque underglazes. These opaque colours are to be used when areas of solid-colour coverage are desired. When one colour is properly applied over another, the second colour will totally block out the first colour. Cover-Coats are applied directly to greenware or 04 bisque then bisque fired to witness cone 04. A glaze finish is required to seal the porous surface and to brighten the underglaze colours, although the fired colours can be left unglazed for decorating effects like the terra-cotta look or polished Cover-Coat.
For most Cover-Coats, any transparent or semi-opaque glaze can be used. On any nonutility item, a nonfired Ceramic Spray or Brush-On Sealer can be used as a finishing coat. Cover-Coat colours will have a more pastel quality when nonfired sealers or matte-finish glazes are applied than when they are finished with a fired Gloss Glaze.
