The term psychometry was first devised in 1842 by Joseph R Buchanan, an American physiologist, who claimed it could be used to measure the soul of all things. Buchanan also said that the past is entombed in the present. 

psychometry involves retrieving information from a non living object. The psychometric picks up emanations ,emotions and the history from the object, these senses could be from the object itself or even the past ,present or future of the owner .Psychometric impressions may come in the form of emotions (clairsentience), sounds (clairaudience), scents, tastes or images (clairvoyance).

Old buildings can sometimes trigger off these feelings, objects that have belonged to families for many years can do also.

Psychometry is often used by mediums to help make contact with a dead person, holding a object that was owned by the deceased can make contacting this spirit much easier. psychics also use psychometry when trying to help in police work, psychics can retrieve information about a missing  person or gaining evidence in a crime.

In order to practise psychometry you will need an object ,jewellery holds energy easily so its a good object to begin with. with your eyes closed ,hold the object with both hands ,get a feel for it, is it rough or smooth ,hot or cold. try to imagine images of the object, obviously the more you practise the more likely you are to improve your ability. Make it a habit of writing down your impressions in a notebook its  good to look back at any successes you might have .Charity and antique shops are a good place to find unusual and old objects to practise on.
