3-D Models

Creating 3-D models of artifacts using photogrammetry

Making the models

3-D models of artifacts were created by taking hundreds of photographs at slightly different angles. The photos were then uploaded into a photogrammetry program (Agisoft PhotoScan). This program was able to overlay each photograph to create a 3-D surface of the artifact, the was later filled in with color and texture. The models were then exported to 3-D printers.

Spindle Whorl

A ceramic spindle whorl recovered from a colonial silver refining mill. Spindle whorls were fitted to the end of wooden spindles and used to increase the speed of the spindle, when spinning raw wool into yarn.

17th-18th century.

Chert Scraper

A stone tool used for scraping and chopping. Made from red chert material. It was uncovered from excavations at a colonial silver refinery, where metal tools were very infrequent.

17th - 18th century.
