The most direct ways in which materials science has contributed to material culture Studies are dating, provenance and conservation. For material culture studies materials science is unique in evaluating material properties which leads to inferences about performanceand characterizing the internal structure which leads to inferences about processing. As a guide towards planning for the future, we have considered the essential nature of objects and devices and what this may suggest for prospective studies. Artifacts are created as purposeful objects; the essential nature of objects is related to their purpose and theoperational principles of how they achieve that purpose. Designers are constrained by these essences of objects and devices; looking at the way in which design tools are used cantell us about human relationships with purpose, operational principle and design. Objectshave both utilitarian and signifying operational principles and normal configurations as well as aesthetic sensibilities. In addition to their purposeful content, objects have non-purposeful unconscious attributes that are related to their cultural origins. The essential nature of objects must always be in the forefront of material culture studies of purposeful artifacts.
