24 Hour Museum: Experts Analyze Bog Butter

Researchers have been studying the "bog butter" regularly found buried in peat bogs in Scotland and Ireland for clues to what the substance really was.

"Bog butter" is a white, paraffin-like substance contained in wooden or skin vessels and is thought to be at least 2000 years old. The research team has concluded that it was probably the remains of meat and dairy products that was stored in the peat for preservation purposes.
