Above the Porcelain White: The Cut a Machine Cannot Make

Craft · Porcelain

As a recognized intangible cultural heritage inheritor of Jingdezhen handcrafted porcelain, Feng Guohua has spent thirty years with one carving knife. A machine, he says, works to a pattern; by hand, every cut carries a decision. His vases are fired to 1,300 °C — in a reducing flame.

In Jingdezhen, white is not one colour. The same clay and the same glaze, and the white that comes out of the kiln still splits into several: some leans blue, some warm, some looks like a thin film of oil under a lamp. None of that is written into a recipe. It comes from the fire.

On Feng Guohua's bench stand a few unglazed blanks, eight of them, mouth down like overturned bowls. Trimming, glazing, firing — all of that is still ahead.

IThirty years, one knife

He was born in 1973, in Jingdezhen. He grew up around this work, he says, and he liked it; in any case nobody stays in this trade without wanting to. In 1999 he was apprenticed to master Wang Changsheng to study porcelain carving, and has since been recognized as a representative intangible cultural heritage inheritor of Jingdezhen's ceramic traditions.

His specialities are relief carving, openwork and applied carving. The knife goes into a half-dry body, which is soft: hesitate for a moment and a piece lifts away. Watch him work a white vase and the front is already covered in scrolling flowers, the petals built up layer by layer until the pattern throws its own shadow.

Cutting. The body is half dry when the knife goes in, and one stroke cannot be taken back.

What the difference is between hand and machine, he puts plainly:

“A machine's work is stock. When we carve by hand, every cut carries its own thought.”

IISeventy-two pairs of hands

The Ming dynasty craft manual Tiangong Kaiwu put it in one line: a single piece passes through seventy-two hands before it becomes a vessel — and the fine details inside those seventy-two steps cannot all be written down.

Five of them are the core: throwing, trimming, glazing, painting, firing. Throwing sets the shape. Trimming thins the wall — the trade saying goes that three parts are throwing and seven are trimming, and a thin-walled piece ends up around half a millimetre. Painting happens on the raw body. Glazing is done by dipping, pouring, blowing or swirling. Then the kiln.

Painting. Blue-and-white is painted onto the raw body, covered with a clear glaze and fired once — the colour cannot fade.

Seventy-two is not the end of it, Feng says. Before the clay there is mining, washing and ageing; after it come saggar-setting and drawing the kiln. “The process is complicated. Sometimes the body cracks, sometimes the firing goes wrong — it comes at you from every direction.”

Across Chinese ceramic arts, whether working with Jingdezhen's high-white kaolin or Yixing's porous purple clay, the master's hand must balance body thickness, moisture, and kiln fire. The same unhurried craftsmanship that shapes carved porcelain defines the ancient clay traditions explored in what makes an authentic Yixing Zisha teapot.

IIIThirteen hundred degrees

Firing is the last step and the least obedient. The old Jingdezhen way burns pine, takes the kiln to between 1,270 and 1,300 °C, runs an oxidising flame first and a reducing flame after, works through three stages, and takes a day and a night — twenty-four hours.

A reducing flame means the kiln is starved of oxygen, so the fire pulls oxygen out of the glaze instead. That is what gives Jingdezhen glazes their faint green-blue and their wet look. Two white porcelains, one from a wood kiln and one from a gas kiln, are not the same white. No recipe supplies that. You wait for the fire.

His clay is a fine, high-white porcelain clay, and what comes out, he says, is “very refined, very beautiful”. He says it quietly. But inside 1,300 degrees, a few tens of degrees or a slightly different atmosphere and it is no longer the white he was after.

IVFewer hands

Thirty years in, the change he sees is simple: fewer people do this now. Once machines arrived, anything that could be made in quantity was, and what is left is worked by hand, day after day.

He does not call it hardship. It can be a hobby, he says, and “to have people like your work — that is an honour too”.

VThe white on the table

In Jingdezhen today, porcelain is not only in the workshop. At the market the stalls stand side by side, bowls and cups and jewellery and ornaments across the tables, and young people crouch to turn a piece over in their hands.

A vase travels from ore to here through seventy-two pairs of hands, a day and a night of fire, and a knife that refuses to hurry. White is the least showy colour and the least forgiving: a little off, and anyone can see it.
