That it continued to be made after the Sung period is practically certain, and there are specimens which one would unhesitatingly regard as Ming or Yüan from their form. But, on the other hand, the prevailing shapes are of the Sung kind, and we have very little to guide us in dealing with the various Chün types except the form and the quality of the ware. The "soft Chün" was very closely imitated at Yi-hsing on a yellowish body which resembles the original in colour, but is generally harder, with a thick unctuous glaze of somewhat crystalline texture and a turquoise lavender colour, with rather thin and feeble patches of dull crimson, which lack the spontaneous appearance of the originals. These Yi-hsing copies are often marked with an incised numeral like the Canton Chün. With regard to the duration of the Chün Chou factories, the standard Chinese works on ceramics are curiously silent. They take no account of the ware after the Sung period, and leave us to infer that it either ceased to be made or ceased to be worthy of mention after that time. In two places only have I found any hint of its survival in later times. One is an incidental mention of Sung, Yuan, and Ming Chün wares in a modern work,[276] and the other is in the pottery (not the porcelain) section in the great K´ang Hsi Encyclopædia.[277] The latter passage is taken from the administrative records of the Ming dynasty, and contains two references to large supplies of vases (_p´ing_ and _t´an_) and wine jars obtained from Chün Chou and Tz´ŭ Chou in the Hsüan Tê period (1426-1436) and in the year 1553 of the Chia Ching period. We further learn that in 1563 an Imperial edict abolished both the tax which had previously been levied on the Chün Chou wares and the subsidy which had to a great extent counterbalanced the tax. These documents prove beyond doubt that potteries of considerable size existed at Chün Chou in the Ming dynasty, though their mention in this particular context seems to imply that the ware was no longer ranked among the porcelains, and had apparently ceased to be regarded as an artistic production. From this time onwards to the present day the ceramic history of this district is a blank, and we are unable to say whether the modern Yü Chou pottery is a continuation or only a revival of the ancient art of the place. A specimen of this modern ware in the Field Museum, Chicago, has close affinities with the "soft Chün." Its base shows a buff stoneware body washed over with dark brown clay, and the glaze is somewhat opalescent though thinner than the old glaze, and its colour is a light blue of a tint more grey than turquoise. Quantities of this modern Yü Chou ware are to be found in Peking, and occasionally it is passed off as old Chün, but no one with experience of the originals would be deceived by it.
