I want to know the answer to the following question:
What type of clay improves the characteristics of the pulps used in papermaking?
All the background I'm provided with is that "Additives for sizing purposes may be mixed with it and/or applied to the paper web later in the manufacturing process; the purpose of such sizing is to establish the correct level of surface absorbency to suit ink or paint.". Is that enough to answer the question?
Answer: no
