This report describes procedures developed to measure shell temper in the exposed edges of archaeological sherd using digital image analysis methods and provides instructions for how to implement these procedures. It also provides confirmation that using a human-checked version of the algorithms included can produce measurements on shell temper comparable to what is achieved with traditional microscopic petrography with considerably less time investment. It further applies this method to achieve two results. In the first instance it is deployed to measure inter-sherd variation and in the second it is used to measure inter-household variation at the Moon Site, Arkansas.
