Alum Instructions
$23.50 ($21.36) / 450 g pack

Used to pre-treat fabric or paper before marbling so designs transfer well.
Alum is also used with some natural dyes as a mordant.


For Fabric Marbling
Dissolve 1/4 cup of alum in one gallon of water. Immerse fabric in solution until wet, wring out (do not rinse) and let air dry. Fabric will be ready to marble when dry. Fabric may be ironed prior to marbling.

For Paper Marbling
Dissolve 1/4 cup of Alum in 1 quart of water. Spray or sponge on the solution to lightly coat the paper. Let dry completely before marbling.
