does not, this would indicate the room without lead paint was a more recent addition. Wallpaper analysis Interest in historic wallpapers developed with the interest in historic paint and color. Investigation into a structure's original appearance can sometimes involve wallpaper, depending on styles and trends that a historic site has evolved through. Paint and wallpaper analysis is closely related when trying to answer the question of a building's original appearance or aesthetic. The main purpose of wallpaper analysis is to identify what wallpaper may have existed within a structure, which provides detail on the site's interior decor scheme during a point in history. Wallpaper and paint analysis become more intertwined when looking at historic paint sample layers, which could also include wallpaper and wallpaper glue. This type of sample can provide detail on whether or not wallpaper was used throughout a structure's history. The style and design of wallpaper found during the wallpaper analysis can be identified by wallpaper historians. The importance of the wallpaper analysis can provide detail about what the appearance may have looked like. Implications As the tools, techniques, and methodologies of historic paint samples evolve, so do the complexities involved in interpretation as nuance adds to an already complicated narrative. Interpretation requires that conservation scientists work in concert with architectural historians to decipher the stratigraphic record, not only to consider the taste and preferences that informed paint selections, but the social, political, and economic climate of their manufacture and consumption as well. For example, conservator and material analyst Kristen Moffitt (Colonial Williamsburg Foundation, Conservation, Conservator & Materials Analyst) tells how Patrick Baty used soot laminated between layers of a sample to determine the point at which the pre- and post-industrial eras diverged, as regulations were introduced into London, England. Likewise, she notes that the color of paint samples can also serve as socio-economic indicators and tell us a lot about the lived-experience of those who inhabited the structure. Mat Webster, executive director for Granger Department of Architectural Preservation and Research at Colonial Williamsburg joins Moffit in noting that samples collected of a deeper, more intense hue are derived from costly pigments imported from England (and initially globally sourced). Therefore, they are used sparingly and appear in only the most public rooms of the house. These data not only inform Material Culture Studies that help the architectural historian and archaeologist model historic economic-trade networks, but help us
