How Alum (potassium aluminium sulphate) is used in Kolkata
- Leather processing: Tanners use alum in tawing, an old mineral tanning method that gives white, soft leather, and it is still used alongside other tanning agents for specific finishes.
- Printing and paper: Paper mills add papermaker's alum with rosin size to make paper less absorbent, so ink sits on the surface and does not bleed through writing and printing grades.
