These guidelines are intended for anyone involved in the storage and display of archaeological metals, including conservators, curators, archaeologists and museum assistants.

It includes an introduction to the reasons why metal objects require particular storage conditions, with detail on the specific problems faced by each metal, based on the latest research. When planning new storage or displays this guide will help to design and implement appropriate environmental controls. It is advisable to consult a conservator in the early stages of planning to address the specific needs of particular objects.
