Extracting
the oil - the boilyards
"The
smell of oil, during its extraction, is undoubtedly disagreeable;
but perhaps no more so than the vapour arising from any other
animal substance submitted to the action of heat when in a putrid
state."
William Scoresby. Account of the Arctic Regions. 1820
Once
back in Port the barrels of blubber were unloaded and taken to the
premises where the oil was extracted. In Peterhead the whalers docked
at the Blubber Box Quay in the south harbour and the barrels were
carted a short distance to the boilyards on Keith Inch.
The
blubber was boiled in copper vessels of up to 10 tons or more capacity.
These were round in section and raised about 6 feet above a furnace.
A pipe, fitted with a stopcock, led from the boiler to wooden coolers
lined with lead or cement and each capable of holding 10 tons of
oil. Oil was run from the coolers directly into casks.
By
the time the ships arrived in port, much of the oil had separated
from the firm, fatty blubber. The contents of the barrels were simply
poured directly into the boilers, filling them almost to the top.
The fire was then lit and the oil brought to the boil. Throughout
the heating the contents were stirred with a wooden pole to prevent
any solids sticking to the sides and burning. When the oil began
to boil the fire was reduced allowing the boil to gently boil for
1-3 hours.
Usually
two loads of blubber could be boiled every 24 hours, the Sabbath
excepted. Once cooled, the oil was in a state ready for immediate
use and was simply transferred from the coolers into wooden barrels
ready for shipment throughout the land.
