Crystal stemware was manufactured for hundreds of years by a large number of manufacturers in a great many patterns, all of which make it difficult to identify. If you’re starting or adding to your collection, be aware of the differences between crystal stemware and regular glassware. In the “Chicago Tribune,” Michele Fecht writes that true crystal has a “lead content of at least 24 percent,” but glass doesn’t contain lead. This lead content gives crystal its signature qualities, contributing to its strength and weight.
The lower temperature required for making leaded crystal makes it easier for glassmakers to craft decorative configurations in crystal glasses such as intricate cuts and angles with sparkling refractions. Overall, crystal has a smoother texture and is heavier than glass, but to positively determine if your crystal is authentic, seek input from a professional service.

China China is effectively expelling a French journalist who criticised Beijing’s treatment of the Muslim Uighur minority in the north-west region of Xinjiang. Beijing is refusing to renew the press visa of Ursula Gauthier, the Beijing correspondent for the weekly L’Obs news magazine. Her visa expires at the end of December and Ms Gauthier will be forced to leave the country. L’Obs said China refused to extend the visa, accusing her of supporting acts of terrorism by writing an article on Uighur minorities.
The story, dated November 18, suggested that China was using last month’s Paris attacks to justify crackdowns on Uighur people in Xinjiang. Hundreds of minorities have been killed in recent years in the region, which is beset by ethnic tensions Uighur groups blame on repressive government policies. China denies any human rights abuses against Uighurs and says it faces a campaign from Islamist radicals and separatists.

Researchers in Iceland have successfully used an existing fibre-optic communications cable to assess seismic activity. Such cables are laid beneath the ground in countries around the world, to supply internet and television service.
The technique has proven sensitive to ground shaking, but is not yet ready for widespread use. It joins a series of recent advances in earthquake sensing, including smartphone apps and more affordable detection hardware.

Technical developments[ edit ] In the context of Chinese ceramics, the term porcelain lacks a universally accepted definition see above. This in turn has led to confusion about when the first Chinese porcelain was made. Kiln technology has always been a key factor in the development of Chinese pottery. These were updraft kilns, often built below ground. Two main types of kiln were developed by about AD and remained in use until modern times. These are the dragon kiln of hilly southern China, usually fuelled by wood, long and thin and running up a slope, and the horseshoe-shaped mantou kiln of the north Chinese plains, smaller and more compact.
In the late Ming, the egg-shaped kiln or zhenyao was developed at Jingdezhen , but mainly used there. This was something of a compromise between the other types, and offered locations in the firing chamber with a range of firing conditions. Early wares[ edit ] Painted jar of the Majiayao culture , Late Neolithic period — BC Pottery dating from 20, years ago was found at the Xianrendong Cave site, in Jiangxi province,   making it among the earliest pottery yet found and so for the moment putting the Chinese ahead in a race with the Japanese in which national prestige is a factor.
Another reported find is from 17, —18, years ago in the Yuchanyan Cave in southern China. Decoration is abstract or stylized animals – fish are a speciality at the river settlement of Banpo. The Majiayao and other phases of the Yangshao culture are well-represented in Western museums; by the Banshan phase purple was used in slip-painting alongside black. Previously coil-forming was used for large vessels. By — BCE in the Dawenkou culture shapes later familiar from Chinese ritual bronzes begin to appear.

Chinese ceramics Porcelain originated in China , and it took a long time to reach the modern material. There is no precise date to separate the production of proto-porcelain from that of porcelain. Although proto-porcelain wares exist dating from the Shang Dynasty — BC , by the time of the Eastern Han Dynasty period BC— AD , glazed ceramic wares had developed into porcelain, on a Chinese definition as high-fired ware. The wares were already exported to the Islamic world , where they were highly prized.
