Loughborough scientists’ new chemical blueprint could be the answer to tackling stone theft

Scientists at Loughborough University hope their early trials of a new chemical blueprint technique could assist a crackdown on stone theft.

Rural parts of Britain have been experiencing a surge in stone thefts recently, including paving slabs and garden ornaments, and as a result, MPs have brought the issue of this new and emerging crime to Parliament’s attention.

The results of a UK heritage crime survey, supervised by Dr Louise Grove at the University’s Department of Social Sciences, and sent to those working in heritage conservation and enforcement, have indicated that stone is now the third most popular target for thieves at heritage sites behind copper and lead[1].

One of the main problems faced by police officers is the mammoth task of tracing unmarked stone once it has been sold on.

But Dr Paul Kelly, of the University’s Chemistry Department, said his research team are in the early stages of trialling a new technique which could prove to be a useful weapon in the fight against stone theft.

The procedure involves extracting a chemical blueprint from stone using a gelatine sheet (the sort normally used to lift developed fingerprints or footprints). The sample is then scanned using laser induced breakdown spectroscopy (LIBS).  

The group has previously shown that the LIBS/gelatine lift combination is effective in metal theft detection and can create a ‘map’ of metal traces that are present on a suspect’s hands. It is this method which Dr Kelly and his team believe has the potential to be used to trace the geographical location of stone by analysing the residual traces on the gelatine sheet.

“We believe our non-invasive technique could provide a much needed link between suspected stolen stone and its original geographical location, but it is very early days” said Dr Kelly.

“This technique of lifting a sample from the surface of stone and scanning it could ultimately lead to us feeding the results into a national database, providing an indication of where geographically that sample came from. This can be done by comparing the stone samples with other stone located across the country and could prove to be a useful point of reference for those tackling stone theft.

“Our preliminary work has produced some encouraging results, and it is possible that our chemical blueprint technique could be the missing piece to the stone theft puzzle.”

Loughborough is one of the country’s leading universities, with an international reputation for research that matters, excellence in teaching, strong links with industry, and unrivalled achievement in sport and its underpinning academic disciplines.

It has been awarded five stars in the independent QS Stars university rating scheme, putting it among the best universities in the world, and was named University of the Year in the What Uni Student Choice Awards 2015.Loughborough is consistently ranked in the top twenty of UK universities in the Times Higher Education’s ‘table of tables’ and is in the top 10 in England for research intensity. It was 2nd in the 2015 THE Student Experience Survey and was named Sports University of the Year 2013-14 by The Times and Sunday Times. In recognition of its contribution to the sector, Loughborough has been awarded seven Queen's Anniversary Prizes.

In 2015 the University will open an additional academic campus in London’s new innovation quarter. Loughborough University London, based on the Queen Elizabeth Olympic Park, will offer postgraduate and executive-level education, as well as research and enterprise opportunities.
