Evidence
"Ash content, wt% 20 (kaolin, alum)"
Remarks
Kaolin is used as a filler in the manufacture of low-quality groundwood paper (Sample P3). It contributes to the high ash content (20 wt%) of the material along with alum sizing (p. 812). Such components can act as catalysts for the oxidation of cellulose (p. 820).
