The error limits on the dates obtained are typically in the range of 5 to 10%.Our standard cost for OSL dating is £550 VAT per sample but prices can vary depending on the nature and number of samples (see our schedule of charges).The age range for pottery and other ceramics covers the entire period in which these materials have been produced.The typical range for burnt stone or sediment is from about 100 to 300,000 years.The particular advantage of luminescence dating is that the method provides a date for the archaeological artefact or deposit itself, rather than for organic material in assumed association.In the case of OSL sediment dating, suitable material (sand or silt-sized grains of quartz and feldspar) is usually available ubiquitously throughout the site.
We are also able to conduct sample collection outside of the UK if the client is willing to cover additional transport, accommodation and subsistence costs.
By around 1750, European ceramic manufacturers had begun a concerted effort to mass-produce fine-bodied, durable earthenwares for the world market.
Their overall plan imitated the Chinese, who had already developed porcelain factories for the production of vessels explicitly designed for export.
Layers of far-travelled volcanic ash (tephra) from explosive volcanic eruptions provide stratigraphic and numerical dating horizons in sedimentary and volcanic sequences.
Such tephra layers may be dispersed over tens to thousands of kilometres from source, reaching far beyond individual volcanic regions. 2, an archaeological site in the infield of the Meyersdale Fairgrounds race track, Somerset County.
