“…The adoption of micro-Raman spectroscopy as a nondestructive technique for the characterization of ancient ceramics has produced a literature extending from Egyptian 18th Dynasty (14th century BC) faience, 1 Vietnamese prototype porcelains and celadons (13-16th centuries), 2,3 Greek terracotta, 4 Islamic (13-17th centuries) faience and pottery, 5 mediaeval-type glazed roof tiles (14-17th centuries), 6 Roman (2nd-3rd centuries) terracotta paint pots 7 and Chinese porcelains. 8,9 From such an eclectic and diverse range of synthetic ware it has been possible to deduce the salient features of the ceramic bodies, glazes and applied pigments, where appropriate.…”

Raman spectroscopic studies were made of a porcelain fragment of a unique 18th century table with inlaid porcelain plaques prior to its restoration and compared with the body and glaze of a damaged, marked porcelain plate from the Rockingham factory. The spectra are consistent with the two specimens having the same manufacturing source around 1840. The analysis of the body of the plate and the plaque fragment shows that both contain b-wollastonite, feldspar and calcium orthophosphate; in addition, a trace of gypsum was found on the bottom surface of the plaque fragment, indicating that plaster was used as an adhesive and bedding agent for the plaques on their wooden table-top substrate. The porcelain bodies of the plaque and the plate are classified as English soft-paste porcelain with bone-ash additive and differences in the spectra can be ascribed to changes in the firing temperature and kiln cycles. The glaze compositions are also very similar with the identification of borax in each specimen. It is concluded analytically that the porcelain plaques were derived from the Rockingham factory around 1835-40, which can be correlated with historical provenancing.

“…2, 3 and 5 the presence of anatase is clearly observed with characteristic bands at 638, 398 and 143 cm −1 [18]. Anatase is a component of the kaolin china clay and is a strong Raman scatterer; it is converted to rutile at temperatures ranging from 400 to 1200 °C and therefore its presence provides a good estimate of kiln temperatures [19][20][21][22]. Although it is recorded in the literature of artists' pigments that anatase is a twentieth century pigment, its presence in ancient Chinese porcelains as a component of kaolin is well-founded from Raman spectroscopic data [23,24].…”

Porcelain shards from Portuguese wrecks: Raman spectroscopic analysis of marine archaeological ceramics

Raman spectroscopic analysis of shards recovered from two Portuguese shipwrecks, the Santo Espirito (1608) and the Santa Maria Madre de Deus (1643), believed to be carrying porcelains of the Ming period have revealed some interesting and novel results that inform historical ideas of porcelain production. The porcelain body of two of the four shards from the Santa Maria Madre de Deus were found to contain anatase, a low temperature polymorph of titanium dioxide, and β-wollastonite a mineral characteristic of soft-paste porcelains that are made at medium-temperature firing conditions. Previously, β-wollastonite has been found in a range of sixteenth to nineteenth century European porcelains but this is the first report of its detection in porcelain believed to be from the Ming period. These same shards exhibited unusual spectral features that were attributed to the resonance enhancement of rare earth elements that resulted from excitation using a near-infrared source.

“…Some bands can be identified, others not. The bands positioned at 235, 440 (under 463 cm -1 ), and 614 cm -1 might be from rutile (TiO 2 ) [30]. The band at 235 cm -1 on the other hand can also be from CaSb 2 O 6 , together with the band at 463 and 669 cm -1 [31].…”

Characterization of Roman glass tesserae from the Coriglia excavation site (Italy) via energy-dispersive X-ray fluorescence spectrometry and Raman spectroscopy

The combined use of handheld energy-dispersive X-ray fluorescence spectrometry, Raman spectroscopy, and micro-energy-dispersive X-ray fluorescence spectrometry permitted the characterization of Roman glass tesserae excavation from the Coriglia (Italy) archeological site. Analyses of ten different glass colors were conducted as spot analyses on intact samples and as both spot analyses and line scans on select cross-sectioned samples. The elemental and molecular information gained from these spectral measurements allowed for the qualitative chemical characterization of the bulk glass, decolorants, opacifiers, and coloring agents. The use of an antimony opacifier in many of the samples supports the late Imperial phasing as determined through numismatic, fresco, ceramics, and architectural evidence. And dealinization of the exterior glass layers caused by the burial environment was confirmed.
