With a high shouldered body tapering towards a spreading foot, covered all over with a deep luxuriant red glaze thinning to pale red and beige around the shoulders, cylindrical neck, and slightly flaring mouthrim, the base covered with a crackled translucent glaze. 

Note: Copper-red glaze is frequently regarded as one of the most challenging to fire successfully. Applying the right thickness of glaze, regulating the right temperature during and after the firing process and determining the appropriate amount of firing time was paramount to achieving rich red vibrant tones. The revival of copper-red which was successfully produced during the Ming dynasty, is largely attributed to Lang Tingji, director of the Jingdezhen official kilns between 1705-1712. The term 'Langyao' is largely believed to be derived from his name: see N.Wood, Chinese Glazes: Their Origins, Chemistry, and Recreation, London, 1999, p.181.
