A number of bronze pieces from the La Joya Huelva excavation have been studied, taking into consideration their composition, the techniques by which they were made, and their minor constituents. The methods used in their restoration are described. Mechanical methods were preferred, using different systems depending on the state of preservation of the article. Similarly, a series of spectrographic analyses were made of bronze pieces from La Ria Huelve and were compared to those from La Joya. It was concluded that although they were found in nearby geographical locations, the technique in which they were made is different.
