If you've ever looked at a piece of Chinese porcelain and seen it described as "blue and white," "famille rose," "monochrome glaze" or "from one of the Five Great Kilns," and wondered how those labels actually relate to each other, you're not alone. Ci Porcelain is an Australian retailer of Chinese porcelain, ranging from everyday bowls and tea ware to decorative pieces, and understanding how a piece is classified is the fastest way to understand what you're actually looking at. In short, Chinese porcelain craft is usually classified along four different axes: by glaze and colour technique, by decoration method, by kiln or place of origin, and by function or form.
This guide walks through each of those four classification systems in turn, and how knowing them actually helps when you're choosing a piece.
What Are the Main Categories of Chinese Porcelain Craft?
Chinese porcelain is most commonly classified along four axes: glaze and colour technique (blue and white, monochrome glazes, doucai, and so on), decoration method (hand-painting, carving, openwork), kiln or place of origin (Jingdezhen, Longquan, Jun kiln, and others), and function or form (everyday ware, display ware, export ware). These categories aren't mutually exclusive — a single piece is usually described using several of them at once. A Jingdezhen-fired, hand-painted blue and white rice bowl, for example, is being classified by origin, by glaze technique and by function all in the same sentence.
Classification by Glaze: Blue and White, Monochrome Glazes, Doucai and Famille Rose
Glaze classification is the most common system, and the core distinction is whether the decoration sits under or over the glaze. Underglaze decoration is painted directly onto the unfired clay body, then sealed beneath a single layer of clear glaze and fired once — the colour is locked under the surface. The best-known example is blue and white porcelain, painted with cobalt oxide, alongside underglaze red, painted with copper-based pigment. Overglaze decoration works the other way around: the piece is fired as plain white or bisque porcelain first, then painted on top of the glaze and fired a second time at a lower temperature. This family includes famille verte (wucai, "five-colour" ware), famille rose (fencai, a softer, more pastel palette that became dominant from the Qing dynasty onward), and falangcai enamels, which were originally developed for the imperial court.
Doucai sits between the two: a blue and white outline is painted and fired underglaze first, then filled in with overglaze colour in a second firing, making it one of the more technically demanding techniques. Monochrome glazes (sometimes called "colour glazes") are different again — the entire piece carries a single glaze colour, with no painted decoration at all. The exact shade, whether it's sky-blue, sacrificial red (jihong) or tea-dust green, comes down to the glaze recipe and the kiln's atmosphere (oxidising or reducing) during firing, which makes this category more about chemistry and kiln control than brushwork.
Classification by Decoration Method: Hand-Painting, Carving and Openwork
Decoration classification describes how a pattern was physically made, rather than what colour it is. Hand-painting is the most common method — a painter works directly on the clay body or glaze surface, which is why no two pieces in a hand-painted series are ever perfectly identical. Carving (sometimes called incising or sgraffito-style cutting) involves cutting a relief pattern into the clay while it's still semi-dry, so the finished texture catches light and shadow differently depending on the angle.
- Openwork: pierced-through holes or patterns cut into the vessel wall, commonly seen on incense burners and lampshades that need to let light or air pass through.
- Appliqué and relief modelling: three-dimensional flowers, figures or animals are shaped separately, then attached to the body of the piece, giving the strongest sculptural effect.
- Gilding: gold lines or gold powder are painted onto the rim or pattern of a finished piece, usually to add a sense of refinement or to define an edge.
Most pieces actually combine more than one decoration method — carving an outline before hand-painting it, for instance, or gilding the rim of an otherwise plain monochrome-glazed piece.
Classification by Kiln and Origin: From the Five Great Kilns to Jingdezhen
Kiln classification groups porcelain by where it was fired and the stylistic traits of that particular kiln system. The most frequently cited group is the "Five Great Kilns" of the Song dynasty: Ru ware (famous for its sky-blue glaze), Guan ware (reserved for the imperial court), Ge ware (known for its distinctive crackle glaze), Jun ware (known for kiln-transformation glazes, where colour and depth vary even within a single firing), and Ding ware (predominantly white, often with carved decoration). Beyond those five, Longquan kiln is renowned for its celadon, and Jingdezhen became China's dominant porcelain centre from the Yuan dynasty onward — often called the "porcelain capital" — with techniques like blue and white and famille rose almost inseparable from its development.
Knowing the kiln matters beyond history trivia — the same glaze technique, blue and white for example, can look noticeably different depending on which kiln and which period it came from, which is part of why kiln origin is such a common reference point when assessing or collecting a piece.
Classification by Function: Everyday Ware, Display Ware and Export Ware
Classifying by function splits porcelain roughly into three groups: everyday ware (bowls, plates, cups, tea sets — anything built for regular use at the table or tea session), display ware (vases, ornaments, incense burners — pieces made primarily to be looked at rather than used), and export ware, which was historically produced in large volumes specifically for European and American markets, often blending traditional Chinese motifs with Western aesthetic preferences compared with pieces made for domestic use. These three categories also tend to differ noticeably in body thickness, decorative complexity and price — everyday ware prioritises durability and practical sizing, while display ware is judged more on form and the fineness of its craftsmanship.
How Does Any of This Help When You're Actually Choosing a Piece?
Knowing these classification systems mostly helps you answer one practical question faster: what is this piece actually for, rather than just whether it looks nice. A quick order to work through when buying:
- Start with function: everyday ware for daily use, display ware if you're buying to decorate or gift.
- Then consider glaze: if you prefer a calm, understated look that won't date, monochrome glazes or blue and white tend to age better visually than heavily painted pieces; if you like richer colour, look toward famille rose or hand-painted designs, such as Ci Porcelain's blue and white porcelain collection.
- Check the decoration method: carved and openwork pieces are generally more labour-intensive and need a little extra care when cleaning around the recessed detail.
- Finally, look closely at glaze evenness and the crispness of any painted lines — that's the quickest way to judge hand-painted quality in person, and Ci Porcelain's celadon and monochrome-glaze collection alongside its decorative pieces collection are useful for comparing this side by side.
Frequently Asked Questions
Is blue and white porcelain underglaze or overglaze?
Blue and white porcelain is underglaze — the cobalt decoration is painted directly onto the clay body and then sealed beneath a single layer of clear glaze in one firing, which is why the surface feels perfectly smooth and the pattern doesn't wear off with regular use.
What's the difference between doucai and famille rose (fencai)?
Doucai starts with a blue and white outline fired underglaze, then has overglaze colour filled in during a second firing, so it requires two firings in total. Famille rose is purely overglaze, with no underglaze outline at all, and its colour transitions are softer and more blended — a technique that only fully matured during the Qing dynasty.
Why does the colour vary slightly on monochrome-glaze pieces?
Monochrome glaze colour is highly sensitive to kiln temperature and atmosphere (whether the firing is oxidising or reducing), so even with an identical glaze recipe, two firings — or even two spots within the same kiln — can come out a shade or two apart. That's considered a natural feature of hand-fired monochrome glaze, not a quality defect.
Are the Five Great Kilns and Jingdezhen the same classification?
No — the Five Great Kilns (Ru, Guan, Ge, Jun and Ding) refer to specific Song-dynasty kilns known for distinct styles and techniques, while Jingdezhen is a production centre that has remained dominant for roughly a thousand years and brought together many different techniques over time. Both fall under "classification by kiln or origin," but they point to different parts of Chinese ceramic history.
Once you can place a piece along these four axes — glaze technique, decoration method, kiln origin and intended function — you're reading it the way a collector would, rather than judging it on looks alone. If you want to compare these categories side by side in person, it's worth browsing through Ci Porcelain's collections to find a piece whose style and purpose actually match what you're looking for.
