HE writes (sumarised):
This advice demonstrates the different types of inscriptions and explains how and why they deteriorate. It also describes how to assess the condition of inscriptions and highlights the range of methods for conservation.
This technical advice forms part of a series of resources produced by Historic England that cover the overall approach to caring for war memorials, including case studies, webinars, advice on structural problems and videos on cleaning and gilding.
