Transfer Printing

By Erica D’EliaAssistant Lab Director

Transferprint_colors

Blue was the first color to be used in underglaze transfer-printing as cobalt was the only color that could withstand the high heat of the firing kiln. Black was next to be introduced and other colors, such as red, purple, green, and brown did not become viable choices until much later. The above sherds are from our type collection and not from a specific site.

We’ve talked a bit about some of the different types of ceramics we find for example tin glaze, white salt-glazed stoneware, creamware, and porcelain, but you might be wondering more about how these pieces were decorated. Our recent work at Ellanor C. Lawrence Park recovered a number of sherds decorated with transfer-printed designs. Underglaze transfer-printing began in the early 1780s and is ubiquitous on archaeological sites through the mid-nineteenth century.

You may already be familiar with transfer-printed tablewares. They are often staples at antique stores and make beautiful decorative pieces (I have a few gracing my dining room hutch at home) and some manufactures, such as Spode, still produce these designs. In the 19th century, people were purchasing full matched sets for their tables. Perhaps the most recognizable element of this technique is the very intricate designs which typically cover the entire vessel. The same pattern is mass produced and can be found on different vessel forms such as plates, platters, teacups, and bowls.

As the name suggests, transfer-printing is a method of transferring an image to ceramic vessels. Before transfer-printing, individual artists painted designs by hand on to each piece, leaving room for much variation and characteristic brush strokes visible on the vessels. Though highly skilled engravers were still needed, transfer-printing required fewer artists and was less labor intensive than hand-painted wares. The patterns produced and use of cobalt blue ink on white-bodied wares served as an imitation of more costly Chinese porcelain.

To create a transfer-print design artists would engrave a reusable copper plate. The plate would be inked and the excess ink removed. Then a piece of tissue paper was placed over the inked engraving. The tissue paper was used to apply or “transfer” the design to the bisque-fired ceramic vessel prior to glazing. Once the design was affixed using soft soap the tissue paper was removed and the piece was dipped into a clear lead glaze and fired to produce the final product. This technique resulted in the ability to produce large quantities of matching vessels and ceramic sets. Transfer-print can be distinguished from hand-painted vessels by the fine detail of the designs, lack of brush strokes, and often a fine stippling or series of diagonal lines visible from the engraving. A short video demonstrating the process can be viewed here. If you’d like to see a more in-depth narrated demonstration check out this video by one of the masters at Spode (I don’t get any kickbacks from Spode, I promise). Often, women usually did most the transferring of the pattern, while children, sometimes younger than ten, performed a number of jobs in the factory.

Transfer-printing was commonly used on white-bodied refined earthenware ceramics. Most of these vessels were produced in England by manufacturers like Wedgwood and Davenport and then exported for the American market. Certain patterns, representing American themes, scenes, and images were even produced specifically for overseas consumption. Some potters identified their pieces by placing their trademark on the bottom of the vessel, but this was by no means a common practice in the 18th and early 19th century. The consumer revolution that occurred throughout the 17th to early 19th centuries ensured that people of all social classes, including slaves, had access to these household goods.

For archaeologists, one of the most useful aspects of transfer-printed wares is the diagnostic utility. Different stylistic motifs on both the central portion of a flatware vessel and the border pattern changed over time and each style was popular for about 15-20 years. Additionally, printing technique and even color can be diagnostic clues. In some cases, we may even have records of the years of production for a specific pattern. One of the most recognizable and enduring patterns is “Willow” a British perception of Chinese culture. A fantastic resource for dating transfer-printed styles can be found courtesy of Jefferson Patterson Park and Museum.

By the latter half of the 19th century demand for transfer-printed vessels declined and were replaced with minimally decorated or undecorated ironstone pieces.

A Bit about Porcelain

44FX3197_44FX224_1719.0007CerUflPclPid_11

by Haley HoffmanArchaeological Intern

Porcelain is a fairly common fine ceramic type composed of white ball clay and fired at temperatures above 1300°C (2372°F). The paste, or body, is highly compacted and ranges in color from white to greyish blue depending on where and how it is produced. Porcelain originated in China during the sixth and seventh centuries but was not available to the West until the sixteenth and seventeenth centuries through Portuguese and Dutch trade. There are two main types of Porcelain, hard paste and soft paste. It can be difficult to differentiate between some hard and soft paste porcelains.

Hard paste porcelain was originally made by the Chinese and is composed of ball clay and a finely ground feldspartic rock, petuntse. Chinese export hard paste porcelain typically has a blue to grey tint. The paste is highly compact due to high firing temperatures for long periods of time and follows a conchoidal fracture pattern similar to other fine grained materials. The glaze is usually fused to the paste. Many describe the glaze as nearly indistinguishable from the paste.

Soft paste porcelain is composed of a variety of different clays in addition to other ingredients like salt and soapstone. Eighteenth century English soft paste porcelain typically has a whiter body with a glaze that is distinguishable from the paste. The glaze was also made of a variety of different compounds and was a semi-gloss that is often distinct from the body of the ceramic. The paste is less compact, or softer, than hard paste porcelain.

One of the most commonly used porcelain decorative techniques for both Chinese export and English production were blue underglazed painted designs. Typical motifs depicted in this technique included animals, floral design, people, architecture and repetitive patterns. Willow Ware was an extremely popular blue underglaze pattern. The design has a characteristic geometric pattern around the rim and a themed landscape picture in the center.

Porcelain’s popularity, copies and reproductions of previous styles have been produced for centuries, can make dating extremely difficult. Regardless of this setback, scholars are working to identify small distinctions in marks and motifs in designs to help identify them. George Miller is one such scholar who in 2002 published an article on the subject titled, Telling Time for Archaeologist.
