 The plasticity gave good reproduction of shape and the low iron content meant there was not discoloration by oxidation when fired at high temperature, giving glazes of high clarity and brilliance.Early examples were individual works of art, notably in barbotine style where a plain base had a design worked in relief with slip and painted, but the company soon developed production lines for decoration of individual shapes, either in a single glaze or painted with flowers and so on (signed by the decorator), for sale at a lower price to a larger market, but still of high quality.Over 2000 different shapes are recorded, including pots, vases, bottles and table items.
