This prayer book belonged to Queen Victoria and was used in the private chapel at Windsor Castle. The edges have been gilded using gold leaf, and then goffered to achieve a decorative pattern. This is achieved by applying heated finishing tools to the gilded edge in order to indent them with small, repeated patterns, resulting in a textured finish. Gilding the edges of a book was not only for decoration, as the gold acted as a buffer and prevented dust from entering the book.
