Available for sale today is an exceptional black transfer mug from the early 19th century. Black transferware was a popular decorative style for ceramics from the mid-18th century to the 19th century, and it was produced primarily in England. This antique mug is unmarked, and it's possible it dates from an earlier period, when marks were less common or not required. Black transferware was especially popular between the 1820s and 1860s. The design is intricate with fine details, so it is likely from the early part of the 19th century.
The early transfer printing process for ceramics, including mugs, was developed in the mid-18th century, primarily in Staffordshire, England. Here's a step-by-step overview of how black transferware was produced:
•
Engraving the Design: A skilled engraver would create the design by carving it into a copper plate. This was a delicate process, as the engraver had to capture the intricate details that would be transferred onto the ceramic piece.
•
Inking the Plate: The engraved copper plate was then coated with a ceramic ink, which was often a mixture of minerals, including oxides, to create the desired color (in this case, black).
•
Transfer Paper: A thin sheet of tissue paper was pressed onto the inked plate to pick up the design. The inked tissue was then carefully removed from the plate. The ink on the tissue would remain wet and ready for transferring.
•
Applying the Transfer: The tissue paper with the inked design was carefully applied to the ceramic mug, which had already been bisque-fired (fired once to harden it). The artisan smoothed out the tissue, ensuring that the ink adhered evenly to the curved surface. This step required precision, as any wrinkles or misalignment could ruin the design. Observe the handle's applied design, noting how it is slightly misaligned with the handle's surface - an excellent example of the handcrafted nature of the production process.
•
Removing the Paper: Once the ink had transferred, the tissue paper was gently peeled away, leaving the design on the surface of the mug. The ink was now on the ceramic, but it was still delicate at this stage.
•
Glazing and Firing: The mug was then covered with a clear glaze, which served to protect the design and give the piece a glossy finish. The glazed mug was fired in a kiln for a second time, permanently fusing the design into the surface and giving it durability and brilliance.
The black transferware process was labor-intensive, but it allowed manufacturers to produce detailed and consistent designs more efficiently than hand-painting. This technique was instrumental in making decorated ceramics affordable to a broader audience during the 18th and 19th centuries.
