Qinzhou nixing clay
Traditional 欽州坭興陶泥
Begin with the sheen: on Qinzhou nixing, the finished surface has been ground and polished. The national heritage record describes bronze, ink-green and purple-red colours appearing after this finishing. A glossy surface therefore asks a process question before it answers a clay question.

How the surface is made
The heritage account describes a body combining hard clay from the west bank and soft clay from the east bank of the Qin River. It provides no mixing ratio. Its account supports the sequence of mixing, firing and polishing, but does not establish a recipe, pigment analysis, fuel or coating for a particular pot.
What the measurements establish
The national heritage record reports firing at approximately 1200 °C. This is a general craft description, with no named test batch, atmosphere, soak time, measuring method or uncertainty. It does not report shrinkage. Its phrase “no pores” is not a measured zero-porosity result. No universal blend ratio or elemental composition is inferred here.
| Reported temperature | Evidence |

| approximately 1200 °C | Ⅷ-98 · 881 · 2008 No comparable shrinkage measurement established. |
What to ask next
Describe the colour, sheen and visible grains separately. Then ask for the clay supplier or batch record, preparation and firing record, and any surface treatment. Composition needs a named, tested sample; a photograph cannot supply it.
