Blue Fir · Decorative Systems
From cobalt fired beneath the glaze to enamels applied after a second, lower-temperature firing, each system carries its own technical logic, historical period, and visual signature — the structural vocabulary through which Jingdezhen porcelain has been decorated for a thousand years.

In Jingdezhen, decoration is not applied — it is constructed. Across dynasties, painters, kiln masters, and enamel specialists developed distinct decorative systems. These systems were not trends. They were technical frameworks: defined by firing sequence, mineral chemistry, pigment stability, and procedural discipline.
A decorative system determines:
When colour is applied
How many firings are required
Which pigments can survive the kiln
How line interacts with glaze
How surface and body relate
It is the invisible structure beneath the visible image. Understanding Jingdezhen porcelain begins here.
Underglaze Systems
Underglaze decoration is applied directly to the porcelain body before glazing and firing. The design is sealed beneath a transparent glaze and fused in a single high-temperature firing. The result is depth, permanence, and structural clarity.
Primary Systems:
Qinghua (Blue-and-White)
Underglaze Red
These systems rely on mineral stability at extreme temperatures and demand precision in brush control.
Explore Underglaze Works →Overglaze Systems
Overglaze decoration is applied after the first high-temperature firing. Enamels are painted onto the glazed surface and fired again at lower temperatures. This allows expanded colour range and greater painterly freedom.
Primary Systems:
Wucai
Fencai (Famille Rose)
Falangcai
These systems require additional firings and layered discipline.
Explore Overglaze Works →Combined Systems
Some decorative systems combine underglaze and overglaze techniques. These require multiple firings, precise alignment of painted layers, and technical control across stages.
Primary System:
Doucai
Doucai represents structural coordination — colour placed above and below glaze in deliberate relationship.
Explore Doucai Works →Monochrome Systems
Not all porcelain relies on painted imagery. Monochrome systems emphasise glaze control, mineral composition, kiln atmosphere, and subtle variation.
Examples include:
Celadon
Blanc de Chine
Copper Reds
Imperial Yellows
In these systems, refinement replaces illustration.

Decoration in Jingdezhen is not an aesthetic layer.
