A certain amount of Chinese pottery found its way, like the celadon porcelains in early times, by the caravan routes into Turkestan, India, Persia, and Western Asia. Such wares would be more naturally drawn from the potteries in Honan, Chihli, and the north–western provinces, and it is not surprising that the fragment found by Sir Aurel Stein in the buried cities of Turkestan should have included the brown painted wares of Tz´ŭ Chou.
But the greatest difficulties in classification are presented by the miscellaneous pottery which collectors have picked up from time to time in China, or antique dealers have sent over to supply the demand created by the increasing interest taken in Chinese pottery by Western amateurs. These come, as a rule, without any hint as to their place of origin, and in most cases it is quite impossible to locate them. There are, however, certain well–defined groups which come together naturally.
One of these is represented by the Tradescant jar in the Ashmolean Museum, Oxford. It was exhibited at the Burlington Fine Arts Club in 1910, and described in the catalogue[423] as "Jar with globular body, short neck, and wide mouth; five loop handles; stoneware covered with a bright green glaze; the ornament consists of floral scrolls in yellow with touches of brown and is in low relief; round the base a formal design. Height, 12 inches." A similar jar is shown on Plate 56, and in the Goff collection in the Brighton Museum is another of the same make, but with the design incised with a point instead of applied in relief. The Tradescant Collection was given to Elias Ashmole in 1659 by John Tradescant. It was formed by the father of the donor, who died in 1627, so that at the lowest computation the antiquity of these wares is fixed in the late Ming period. Another group is represented by Plate 58, Fig. 2. Its characteristics are a comparatively thin buff earthenware body, soft enough to powder under the knife, and a sparing use of brownish yellow, bright turquoise, green[424] and aubergine glazes of the usual crackled type applied direct to the body. The specimens are generally vases or incense burners of curious and archaic forms, with ornament moulded in low relief, the whole bearing the unmistakable signs of a ware which has been pressed in a mould. The inside and bottom of the incense burners are usually unglazed. The colours, as a rule, are pleasing and soft, and it is the common practice to label them indiscriminately Ming. As nothing definite is known of their place of origin, this chronology can only be based on their archaistic appearance, or on the fact that they have the usual "on biscuit" glazes, which seems to be the accepted signal for a Ming attribution. Needless to say, the use of this method of colouring survived the demise of the last Ming emperor, and it is improbable that wares which must be comparatively common in China (judging from the handsome way in which the quite recently created demand for them has been answered) should have a minimum antiquity of two hundred and seventy years.
The fact is that dating of these glazed potteries is as difficult as that of the cognate glazed tiles, and it is as unreasonable to exclude a Ch´ing origin as it would be to exclude a Ming. The balance of probabilities, at any rate, is in favour of the bulk of them being no older than the eighteenth century.

A third group is also consistently labelled Ming, but with better reason, though even here a little more elasticity in the dating is advisable. It has an exact parallel in porcelains of undoubted Ming origin, viz. those represented by Plate 61, etc., which usually take the form of jars and vases with designs outlined in fillets of clay, or channelled or even pierced à jour. The spaces between the outlines are filled with coloured glazes which are fired, in the case of porcelain, in the cooler parts of the biscuit kiln. These are the glazes de demi–grand feu, according to the French definition, and they consist of turquoise and aubergine purple or violet and green (the three colours or san ts´ai, all minutely crackled), supplemented by a white formed by slip and a thin brownish yellow. Occasionally the purple is so deep as to appear almost black; and the details of the designs are often etched in the paste with a fine point. Precisely similar wares are found with an earthenware body; and they are, no doubt, contemporary with the analogous porcelains, though how long the traditions of this type of ware continued has never been precisely determined. The porcelain on which washes of turquoise and aubergine glaze are combined is a development of this type, and this has certainly survived to comparatively modern times. Reticulated ornament was used on the three–colour pottery vases no less than on the porcelain (Plate 55); and besides the covered wine jars and vases there are figures and grotto pieces of similar style both in pottery and porcelain, many of which must date from Ming times.
