In the 1990s, KPM began to re-emphasize its cultural and craft traditions. It rediscovered historic shapes, colours and patterns. Important dinner services from the era of New Objectivity were reissued. After the triumphant success of a vase collection launched in 1994, KPM presented the BERLIN dinner service, created in cooperation with the Italian modernist designer Enzo Mari. From 1998 to 2003, the KPM QUARTIER was refurbished by architects Gerkan, Marg and Partners according to curatorial standards. At the same time, the production technology was updated. In 2006, after several previous attempts at privatisation, Berlin banker Jörg Woltmann took over the Royal Porcelain Manufactory Berlin and became the sole shareholder. In the same year, KPM opened its newly designed sales gallery in the historic kiln hall. Additional KPM shops are located in Berlin, Potsdam, Hamburg and Cologne. In 2007, the company opened the KPM WELT exhibition at the KPM QUARTIER, a company museum dedicated to the company's 250 years of history and craftsmanship of making porcelain. In the recent past, new ground has been broken through collaborations with luxury brands, such as Bottega Veneta and Bugatti Automobiles. In 2011, KPM designed the exterior and interior of a Bugatti Veyron Grand Sport “L’Or Blanc” in cooperation with the car manufacturer. In 2012, a Bugatti Veyron Grand Sport “Wei Long” was outfitted with dragon motifs. On the occasion of KPM's 250th anniversary in 2013, the special exhibition Royal Porcelain Manufactory Berlin 1763-2013 provided a representative overview of the manufactory's creative periods, with 300 works from 18 private collections. Brand Sceptre When Frederick the Great took over the manufactory from the Berlin merchant Johann Ernst Gotzkowsky on 19 September 1763, he also provided the brand's emblem: the cobalt blue sceptre from the electoral coat-of-arms of Brandenburg. The porcelain is marked after the first firing and before the glazing process. Before the sceptre is applied to the porcelain, the item is subject to strict quality control measures. Afterwards, the porcelain is glazed and fired for the second time. The color bonds inseparably with the glaze and makes the piece of porcelain forgery-proof. In the beginning, the trademark was applied in blue on white porcelain and in brown on painted porcelain. In 1837, the letters KPM were added to protect the brand from counterfeits. A few years later, the royal Prussian eagle became part of the trademark. In the following decades, the trademark underwent slight changes
