The "yolk" or "suint" of wool, originating from the perspiration of the animal, has long been a source of crude potash.
It is easily seen that suint forms a very important constituent of raw wool.
He adapts his method to securing the suint to wool-washing establishments at a small cost.
By this method all the wool fat, suint, etc., of the wool find their way into the soap liquors.
And this estimate does not include the fats of the suint, which are worth an even greater sum.
All unwashed wool contains a fatty or greasy matter called yolk or suint.
