tallow

   “Nor were the wool prospects much better. The pastoral industry, which had weathered the severe depression of the early forties by recourse to boiling down the sheep for their tallow, and was now firmly re-established as the staple industry of the colony, was threatened once more with eclipse.”

   “Rendering is done by boiling the animal carcasses to separate the fat from the meat. At high temperatures, the fat floats as a creamy white substance called tallow, while the heavier protein sinks to the bottom, producing greaves, which can be fed to animals. Tallow is used to make candle wax or is mixed with ash and heated again to form soap.”
