The Oxbow Archaeologists have recovered two "tombac" buttons during the course of excavations. Tombac was a brass alloy with a high percentages of zinc and sometimes arsenic. This alloy can range from yellow to aluminum in color. It is often still shiny when excavated and was commonly used for buttons in the eighteenth century, particularly 1770-1800 (see Warren K. Tice, Uniform Buttons of the United States 1776-1865, page 2). These buttons are common on Revolutionary War period sites and have also been found at the Battle of Fallen Timbers battlefield in Ohio
