SUMMARY

Soldering using nitrate of silver - A previously undescribed prehistoric soldering method?

A gold berlogue from the Roman Iron Age (figs. 1-2) found in southern Jutland was ex­

a!Tllned to decide the method of production.

Analysis of the fragments were carried out using SEM (scanning electron m_icroscopy) combined with a guality examination (EDX). Chemical soldering using copper ni­

trate in antiguity is described in literature.

However, the analysis of this berloque in-

312

dicates the use of chemical soldering using silver. Practical experiments suggest that sol­

dering granulated gold using silver nitrate is possible.
