Characteristics of Nantgarw and Swansea China.
Nantgarw porcelain is of very fine texture; it has a glassy appearance, and when held up to a strong light, such as an incandescent electric globe, it exhibits a number of small bubbles, like pin-holes, in the body. It is inclined to have the glaze cracked in parts with a network almost like Chinese crackle ware. Some of the thinner pieces will be found to be not quite true, being slightly warped or bent, owing to its uncertainty in the kiln.
Swansea china is frequently decorated with birds, butterflies, and shells, drawn from nature by W. W. Young. Much of it is of a glassy nature like Nantgarw; but later the Swansea ware was of a duller, heavier nature, and having a hard white appearance.
