Summary: Shards of Blue-and-White Ming porcelain from shipwrecks of Portuguese ships found on the coasts of South Africa, as well as a shard from Mombasa (Kenya), were analyzed using optical microscopy, SEM-EDS, and Raman microspectroscopy. The study revealed differences in the composition of the porcelain body paste and types of glazes used, with blue decoration characteristic of materials rich in manganese.

Summary: The earliest use of cobalt on porcelain can be traced back to the Tang dynasty, but it was not until the late Yuan dynasty that the production of widely known blue-and-white porcelain in Jingdezhen matured. Studies have focused on the sources of blue pigments used in the Yuan and Ming dynasties. Analysis of blue-and-white porcelain fragments from Jingdezhen minyao sites revealed a closer correlation of cobalt pigments used during the Kangxi, Yongzheng, and Qianlong reigns to Yunnan asbolites rather than the previously accepted Zhejiang asbolites.

Summary: This study examines the early European porcelains made before the discovery of kaolin in Saxony, Germany. Analysis of blue-and-white artifacts from French national collection revealed different factories of origin and enamel types used. Mobile XRF and Raman instruments proved useful for on-site classification of artifacts.

Summary: This study focuses on the color variations and frosted appearance of Chinese blue-and-white porcelain produced in folk kilns and recovered in underwater archaeological contexts. The results suggest that these variations are mainly attributed to the production process, composition, and firing conditions of the ware, as well as the switch from foreign to domestic pigment sources during the late Ming period.

Summary: Chinese blue-and-white porcelain is significant evidence of global trade routes and cultural exchange. Research has shown that the blue color of the porcelain is determined by the speciation of cobalt and iron, which can also be affected by the firing atmosphere conditions.

Summary: This study used Energy Dispersive X-Ray Fluorescence, field emission scanning electron microscopy, and X-ray Absorption Fine Structure analysis to investigate the formation mechanism of 'Huoshihong' on the blue-and-white porcelain body of the Yuan Dynasty. The results showed that the formation of 'Huoshihong' is dependent on the presence of a liquid phase and the occurrence and re-oxidation of Fe2+.

Summary: The chronological classification studies of Jingdezhen blue and white porcelain have high research value due to its academic and socio-economic significance. The paper uses hyperspectral remote sensing techniques to study Jingdezhen porcelain of different ages, and constructs a model of typical spectral features that are sensitive to the material type and age information of blue and white porcelain. The classification of Jingdezhen porcelain from various ages can be achieved using a combination of hyperspectral remote sensing technique, random forest algorithm, and long short-term memory.

Summary: This in vitro study examined the effects of different manufacturing techniques on the metal-ceramic interface and bond strength of cobalt chromium (Co-Cr) alloy restorations. The results showed that the manufacturing method had a significant effect on the bond strength, while thermal cycling had no effect. The bond strength values in all groups exceeded the clinically acceptable threshold of 25 MPa.

Summary: Recently, there has been an increasing demand for white-firing clay materials in ceramic tile production due to a shift towards porcelain stoneware bodies. However, the industry is facing challenges in meeting the clay demand for porcelain stoneware production through established commercial channels. In this study, the researchers explored the potential of Tabarka clays in Tunisia for porcelain stoneware production and found that they exhibited suitable technological behavior. The properties of fired bodies based on Tabarka clays fulfilled the technical requirements for porcelain stoneware tiles.

Summary: Lead-barium glass, considered a Chinese invention from the late Warring States period, was studied for its unique properties and possible raw materials. The function and source of sodium in this glass were explored, leading to the proposal of a new formulation involving sodium flux from soda-lime glass to explain its origin.
