In Their Cups?: Background lipids in shell as a basis for analyzing shell cup residues (2016)
DOCUMENT

Lipids in a variety of large shells were extracted using both destructive and non-destructive techniques and analyzed with GC/MS. In pottery residue analysis, lipids found in extracted residues can be assumed to derive from human usage because natural geolipids are removed from the clay during firing. Shell cups do not undergo firing at temperatures high enough to result in lipid removal. As a result, it is important to understand the natural lipids present in large shells before attempting...
