Let's talk wool prices and clear up some of the confusion around
Clean Wool Price vs Greasy Wool Price.
When wool comes off the sheep, it contains grease (lanolin), dirt, moisture, and vegetable matter. This is called greasy wool, and the price quoted on this basis is the greasy wool price.
After the wool is scoured (washed) and all the impurities are removed, what's left is the actual usable fibre. The value of this fibre is expressed as the clean wool price (COF)
Think of it this way:
🐑 Greasy Wool Price = Price for the raw wool straight off the sheep.
🧶 Clean Wool Price (COF)= Price for the actual wool fibre after its washed.
Working Equations
Clean Wool Price = Greasy Wool Price ÷ Clean Yield (decimal)
Greasy Wool Price = Clean Wool Price × Clean Yield (decimal)
