Furnace

In 79 AD, Rome used old wood-burning furnaces whilst the more advanced Pompeii used hypocausts with hot springs leading from Mount Vesuvius, an innovation from the soothsayers following the great earthquake of 62. (TV: The Fires of Pompeii)

The Clocksmith threatened to kill Apolena using a furnace. (AUDIO: The Eighth Piece)
