A mordant is a chemical that combines with the
paint and fixes it permanently on the paper.
- Alum: which can be any of the following three - aluminium sulphate,
potassium aluminium sulphate or ammonium aluminium sulphate.
- Mix two tablespoons alum with one
pint of hot, distilled or soft water. Dissolve completely and
allow to cool.
- Sponge onto each paper to be marbled, and the paper is allowed to
dry, but keep damp.
- Protective gloves or cream: to protect your
hands from the toxic or irritating properties of some paints and alum.
- Alum (Aluminum Sulphate): Mix two tablespoons alum with one
pint of hot, distilled or soft water.
- The alum is what
will bond the color to the paper. Treat paper or fabric with the mordant
solution, if necessary.
