New ceramic dating process unearthed By Lewis Brindley20 May No comments By measuring moisture recombination in ceramics, scientists have found a new way to date ancient pottery and brickwork A new way to find the age of ceramic objects, such as ancient pottery, has been developed by scientists in the UK. The technique measures how much water the items have absorbed since they were fired – simply and accurately revealing when they were made. Broken pottery, brickwork or tiles are unearthed at almost every archaeological dig site, but they are often of little use to archaeologists as determining how old they are is difficult.

Carbon dating cannot be used because ceramics are made from finely-grained mineral clay, and alternative dating methods are complex and costly. Now, UK scientists have found a way to date these artefacts and thus give fresh insight into the history and construction of excavated ruins or items. The laboratory procedure is simple: Then, because mineral clay composition can vary wildly between different ceramics, the sample is monitored to determine the rate at which it picks up water – allowing the age to be calculated.

The researchers indicate that the technique may also find uses in spotting fake objects or uncovering whether buildings have been re-built or experienced a fire. For example, while testing a variety of bricks and tiles provided by the Museum of London – including Roman, medieval and modern samples – all but one of the samples were accurately dated. The sample that threw the results was a clay brick from a medieval priory in Canterbury, UK, which was dated at only 66 years old instead of several hundred.

On further investigation, the team found that the priory had been bombed during World War II, resulting in the clay bricks being heated over ? C, which would have dried them out and thus affected the results.

I received a copy of this book for free in order to review it. Dating the Second Time Around is a book written for a very specific audience: Based on the fact that eHarmony is associated with this book, I assumed prior to reading it that it would also be for those specifically looking to date online. But more on that later. Instead it is a book about searching, finding, cultivating and then maintaining a healthy relationship.

From what I can tell, the authors are writing for the benefit of their readers not the benefit of eHarmony.

Social trends[ edit ] Since the s, Internet dating has become more popular with smartphones. The stigma associated with online dating dropped over the years and people view online dating more positively. Further, during this period, the usage among to year-olds tripled, while that among to year-olds doubled. Online introduction services[ edit ] In , a variation of the online dating model emerged in the form of introduction sites, where members have to search and contact other members, who introduce them to other members whom they deem compatible.

Introduction sites differ from the traditional online dating model, and attracted a large number of users and significant investor interest. Such sites earn revenue from a mix of advertising and sale of additional options. This model also allows users to switch between free and paying status at will, with sites accepting a variety of online currencies and payment options.

Since advertising revenues are modest compared to membership fees, this model requires a large number of page views to achieve profitability. However, Sam Yagan describes dating sites as ideal advertising platforms because of the wealth of demographic data made available by users. While some sites conduct background checks on members, many do not, resulting in some uncertainty around members’ identities.

For instance, some profiles may not represent real humans but rather “bait profiles” placed online by site owners to attract new paying members, or “spam profiles” created by advertisers to market services and products. Profiles created by real humans also have the potential to be problematic. For example, online dating sites may expose more female members in particular to stalking , fraud , and sexual violence by online predators.
