As Majolica, 1st apply 2-3 coats of a base white glaze to a Cone 04/03 bisque piece (Spectrum recommends #799 Majolica White) and allow to dry thoroughly. Paint 300 series colors directly on top of the unfired white glaze surface: One Coat gives the traditional Majolica look in which some of the white background shows through. Two Coats will yield more opaque colored designs. Fire to Cone 05. As Underglaze, apply to Cone 04/03 bisque. One Coat for semi-transparent color: Two Coats for semi-opaque color: Three Coats for solid opaque coverage. Allow to dry thoroughly and cover with 2 coats of #700 clear. Fire to Cone 05. As Glaze, apply 3 brushed coats to Cone 04/03 bisque and fire to Cone 05. The colors will vitrify with a medium-gloss surface: (not quite as shiny as the 700 Series Glazes).
