Pottery Marks
Patent Office Registration Marks And Numbers.
Diamond shaped pottery marks, printed or impressed on the base, are official marks of the Patent Office Registry of Designs, set up in 1842 to protect manufacturers from plagiarism and piracy.
In 1868 the positions of the code letters and numbers were changed, but the registration mark continued until December 1883, when it was replaced by a serial number
Registration of a design gave three years protection, during which time there could be continuous or sporadic production of the design or pattern.
