Abstract

Metal archaeological objects excavated from the sea need application of a removable, invisible coating to protect them from further corrosion during display in the museum and/or storage. Typically, these coatings are applied by brush and sometimes by spray. These coatings are often based on wax e.g. paraffin wax although more specific acrylic types (the Paraloid series) are also used. A protection provided by the coating is challenged by two aspects. First, normally applicators are not aware as to how thick the coatings are after application to real objects. Secondly, users have no way of discovering the optimum number of coats; or of monitoring the performance of the coating in service. Therefore, a numerical assessment method is required. This work looks at developing such a method.
