Ancient Furnace

are objects in.

Location and Uses
The Ancient Furnaces are found nearby the Akkala Ancient Tech Lab and the Hateno Ancient Tech Lab. The Blue Flame inside the furnace is needed to be put back in the Blue Flame Pedestals in the tech labs to then activate ancient machinery, such as Cherry the Ancient Oven. Activating these machines will allow Link to obtain Ancient Weapons, such as Ancient Bladesaws, or upgrade his Sheikah Slate Runes, such as the Stasis Rune.
