Berlin: KPM Royal Porcelain Manufactory
Berlin porcelain refers primarily to the products of the Konigliche Porzellan-Manufaktur (KPM), the Royal Porcelain Manufactory established in 1763 by Frederick the Great of Prussia. KPM Berlin has produced some of the finest hard-paste porcelain in European history, renowned for its exceptional painting, rich gilding, and technical perfection. The factory's blue sceptre mark is one of the most prestigious in the porcelain world, and KPM pieces -- from elaborate dinner services to finely painted plaques -- command strong prices from collectors specializing in Continental porcelain.
Types and Major Productions
- Painted porcelain plaques: KPM's most collected product; rectangular porcelain panels painted with portraits, mythological scenes, and copies of Old Master paintings; produced primarily 1830s-1920s
- Dinner services: Elaborate services in patterns such as Neuzierat, Kurland, and Neuosier; commissioned by Prussian royalty and wealthy patrons
- Figurines and groups: Modeled by artists including Friedrich Elias Meyer and the Muller brothers; Rococo and Neoclassical subjects
- Vases and garnitures: Monumental vases with painted panels, often depicting Berlin landscapes or classical scenes
- Lithophanes: Thin translucent porcelain panels revealing images when backlit; a KPM specialty from the 1830s
- Modern KPM: The factory continues production today; contemporary artist collaborations and traditional patterns
Identification and Marks
- Blue sceptre mark: The primary factory mark since 1763; a cobalt blue sceptre (scepter) painted or printed underglaze; style varies by period
- Red orb mark (KPM): Used on pieces decorated at the factory; indicates factory-quality painting
- Impressed marks: Letters, numbers, and symbols indicating form, size, painter, and date of production
- Plaque marks: Genuine KPM plaques bear the sceptre mark on the reverse, often with impressed "KPM" and size numbers
- Period identification: The style of the sceptre mark helps date pieces; earlier marks are more crudely painted; later marks are crisper and more standardized
- Fakes and copies: KPM plaques are among the most frequently faked porcelain items; study mark placement, porcelain quality, and painting technique

Condition Factors
- Plaque painting quality: The quality of the painted image is the primary value determinant; fine detail, luminous flesh tones, and careful composition are essential
- Plaque condition: Any crack, chip, or repair to a KPM plaque dramatically reduces value; plaques should be examined under raking light
- Frame: Many KPM plaques are in ornate gilt frames; original or period frames add value
- Gilding wear: Extensive gold decoration on tableware and vases wears with use; strong original gilding commands premiums
- Restoration: Professional restoration of figures and vases is common but must be disclosed; unrestored pieces are preferred
Collecting Tips
- Painted plaques dominate the market: KPM plaques are the most actively traded category and the most likely to appreciate; prioritize quality of painting above all
- Authentication is critical: KPM plaques are widely faked; examine the porcelain body (should be smooth, white, and even), the mark (should be underglaze), and the painting technique (should show fine brushwork under magnification)
- Subject matter drives price: Female portraits (especially after Raphael's Madonnas) and reclining nudes command the highest prices; landscape and still-life subjects are less valued
- Size matters: Larger plaques with complex compositions are exponentially more valuable than small, simple ones
- 18th-century figures are the connoisseur's choice: Frederick the Great-era figures by Meyer are rare, refined, and appreciated by serious European porcelain collectors
- Modern KPM is collectible: Contemporary KPM collaborations with artists and designers are gaining collector interest at accessible prices
