I ❤ Ceramic Fish Cookers

Ancient Japanese pottery has been found that suggests that hunter-gatherers were using vessels such as the pot found to prepare food. The chemical analysis reveals that this pot was used between 11,200 and 15,300 years ago to cook a type of fish. They found it was fish because even though fatty acids don't tend to preserve well, they found small samples that were left within the stains on the inside of the pot. This type of pottery has been questioned for years, and is now just being traced to hunter-gatherer tribes in ancient china.
