It took five full days to finish rendering all the subcutaneous fat.
On the afternoon of February 3, Chen Zhou finished rendering the last chunk of fat and poured the cool seal oil into plastic bags—hot oil would melt the plastic bags.
Then he arranged the 5kg plastic bags onto wooden shelves in a dark, dry storage room to be used later.
There were four types of seal oil packaging: glass containers, glass jars, large barrels, and plastic bags.
Chen Zhou planned to use the oil from the glass containers and large barrels as cooking oil. There were about ninety jin of this oil, which would last three years if he did not fry and sauté too frequently.
During these three years, even if no more seals landed here, he could fish and render oil or go to the other side of the island to hunt penguins for oil to replenish the fats.
As for the seal oil in plastic bags, it was reserved for lamp oil, expected to sustain high-intensity usage for over a year without issue.
