METHODOLOGY<br />

Samples were collected from 23 locations inside the <strong>Pitcher</strong> Farmhouse on 5 February<br />

2015. These locations were selected in order to compare the chromochronology<br />

between rooms and to test theories of evolution within the structure. Samples were<br />

collected from the surface to the substrate using a utility knife and chisel. Substrate<br />

materials are lime plaster for most of the walls and wood for trim, anchor posts, and<br />

beams.<br />

Samples of finishes were mounted in wax and viewed through a CE Premier Student<br />

Microscope and photographed with an iPhone 5S, using a Carson universal smartphone<br />

optics adapter.<br />

Data was collected visually regarding number of layers, colors, and finishes; and then<br />

analyzed for identification of substrate material and documentation of layer<br />

stratigraphy. In a few cases, attempts were made at identifying binders and matching<br />

colors within the sample to commercial paint samples and/or Munsell chips. However,<br />

the goal of this study was comparative analysis among samples rather than in-depth<br />

chemical identification.<br />

For samples where chemical testing was performed, reactions were observed upon the<br />

application of swabs from a rhodizonate lead test kit, water, vinegar, ammonia,<br />

denatured alcohol, mineral spirits, laquer thinner, and xylene.<br />
