Crystalites Mayco's Crystalites are gloss glaze bases with pieces of glass frit that melts during the firing process. As the crystals bloom, they produce dramatic, colourful effects. * Combine Crystalites with other Mayco Glazes for dramatic effect * Not recommended for dinnerware due to surface characteristics * Non-toxic * Fires to cone 06 - 04 (999 - 1060C) * If fired higher, the glazes retain their base colour but with increased crystal movement
