- Archival Materials
Different types of paper and pigments have varying degrees of susceptibility to fading over time. The main cause of this is exposure to UV (ultra violet) light, although humidity, temperature, pollution and acidity are all contributing factors.
Archival images use only archival materials which are free from the acids present in most common papers which react with UV light to damage the paper fibres, and from fugitive pigments.
Exposure to direct sunlight should be avoided, and UV-resistant glass can be used when framing. If these guidelines are followed, archival images will comfortably last a lifetime, with many having a lifespan in excess of 120 years.

- Papier mache
Papier-mâché (French for 'chewed-up paper') is a modelling material made by tearing or cutting paper and then soaking it in a wet paste e.g., glue, starch, or wallpaper adhesive. The paper/glue mixture is then applied to an object which acts as a cast. The surface of the pulp can be manipulated whilst still wet by being impressed or carved into or can be embellished with elements such a stones, shells or beads. Once dry piece can be cut, sanded, painted or varnished.
