All positions are filled with talented individuals. But Gotzkowsky's financial situation becomes more and more precarious. Because the royal account is already overdrawn, due to the cost of the war, Gotzkowsky doesn't see any chance of obtaining any grants or subsidies whatsoever from the king.

The end of the war also spells the end of Gotzkowsky's entrepreneurial involvement. On 4 August 1763, he stops paying salaries. The king himself appears on the scene and buys the porcelain production company from Gotzkowsky for the considerable sum of 225,000 Reichstaler. He keeps the entire staff of 146 employees. But the rescuer is acting on very pragmatic grounds: He wants to stimulate the Brandenburg economy. On 19 September, Frederick II assumes official control of the company. He gives it its name and emblem: the royal sceptre. From now on, the company bears the name of Königliche Porzellan-Manufaktur Berlin (KPM). Underneath every piece is the trademark of the sceptre. KPM becomes a model business: regulated hours of work, higher-than-average earnings, secured pensions, company health insurance, and benefits for widows and orphans. Child labour is forbidden by the king, not merely for humane reasons but also for professional reasons: Only highly qualified specialists can maintain the high level that he sets as the standard for production.

Operations are streamlined and techniques are perfected. KPM becomes what it is today: An operation based on economic principles and one that takes "manu factum" literally. Handcrafted articles are the basis of the company and its success. In 1767, the NEUZIERAT, NEUGLATT and ROCAILLE dinner services are created, followed by NEUOSIER in 1770.

In 1784, after four years of development work, the royal request for a matt, soft blue colour is fulfilled – the so-called bleu mourant. Frederick's favourite service, the NEUZIERAT form, is decorated in it. A word often quoted by Berliners can be traced back to this:  When Berliners feel as drop-dead tired as this blue, they say they're "blümerant" (queasy).
