Bronze sampling

If you would like your bronze casting core tested, get in touch with us via our contact form. We will need to know where the piece is located so we can recommend the closest sampling agent to you, or arrange to come and sample it ourselves.

Sampling

All sampling is carried out in a darkened room by an accredited agent.

Most bronze pieces are made by casting molten bronze round a clay mould.  In many cases the casting core is left inside the object.  If a thick deposit of fired clay is visible, it will be possible to take a sample simply by scraping through an opening or from the base.

Often there is casting core trapped inside otherwise hollow sections such as handles legs, heads or torsos.  In these cases it is necessary to drill a small hole in the metal to reach the core.

An image of the piece must be submitted with the sample.  This may be an actual photo, or on a CD or emailed to us by the agent. Details are entered onto a data card which is sent along with any photographs and the sample(s) to our laboratory for testing.
