Müller, on his secret mission in Germany, found that the china factories of Fürstenberg, Meissen, and Berlin were closed to him. But he threw his whole life and energy into his work. He outlived the opposition of the Society of Apothecaries, who objected to a licence being granted him as a druggist and dispenser. But in face of the objection the College of Medicine found the applicant "a very capable, learned, and experienced man, not only in Pharmacy, but also in Chemistry, Assaying, and Natural History." With characteristic energy he passed the pharmaceutical examination at the age of forty-one; already he had shown originality and inventiveness by making several discoveries in colours and in dyeing. But with all his virility he found financial success no easy matter at such a disturbed period. He endeavoured to form a company for the manufacture of Danish porcelain. To his chagrin, only one share was sold. At the outset there was little promise that his untiring efforts would win the remotest recognition from his countrymen. It seemed imminent that the whole enterprise would have to be abandoned. Happily, Privy Chancellor Holm, the private secretary to the Dowager-Queen Juliane Marie, saw possibilities in the venture. To revive the old factory which Fournier had vacated was an opportunity not to be missed. If it proved a success, it would redound to the credit of the queen and add lustre to the new _régime_ just commenced under the sway of Juliane Marie, with Guldberg as the power behind the throne. Christian VII had simply passed as a signer of documents into the keeping of another set of masters. Of the shares, most of them in the new factory were held by members of the royal family and one by Müller himself. The directors were Holm; Suhm, the historian; General Eickstedt, one of the conspirators who took a leading part in the arrest at the masked ball; and Guldberg, who had a finger in every pie. On the 13th of March 1775 the company obtained the monopoly of the manufacture of porcelain in all the dominions of the King of Denmark, in spite of the opposition of the Board of Trade. =The Origin of the Mark of the Three Blue Lines.=--The first meeting of the company was held on the 1st of May 1775. It was decided that the trade-mark of the factory, according to the proposal of Queen Juliane Marie, should be three wavy lines, always marked in blue, representing Denmark's three waterways--_Oresund_, and the two belts: _Storebelt_, between Sjaelland and Fyen; _Lillebelt_, between Fyen and Jutland. With this trade-mark of the three blue lines the Copenhagen factory (_Den Danske Porcellænsfabrik_) took its place beside the older factories on the Continent, and to this day, a hundred and forty-three years afterwards, this same mark appears on all porcelain emanating from the Royal Copenhagen Factory.
