Cone 6: Honeycomb is a variegated brown matte glaze that contains a sandy-brown crystal. As the crystal melts it creates glossy blooms that can produce yellow mottling in the glaze, producing a textured fired finish. Cone 10: Color darkens. TIP: SW-103 Sisal is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-103 Sisal with a third coat of SW-117 Honeycomb.
