Cone 6: Blue Splatterware is a white, semi-matte glaze that contains a blue crystal. As the crystal melts it creates small blue blooms that cause the glaze to resemble the look of 19th century enamelware.
Cone 10: Crystals become less defined.
Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination.
