Marbling Marbling is a method of decorating paper or fabric by floating pigments or colours on a sizing solution. Carrageen is used to develop the appropriate viscosity of the sizing solution to maintain the colours and pattern on the solution surface. The colours can then be combed or manipulated into various patterns. SOLVENT BASED INKS |

INKS INKS: Squeeze about 5 cm of ink into a
small container and thin with White Spirit until the ink is
consistency of thin cream. Mix thoroughly. Gently place
individual drops onto the Carrageen solution. Each drop
should spread about 5 cm in diameter - this indicates that
the ink is of the correct consistency. LAYING ORDER OF INKS: Some colours
spread easier than others. For best results, use your
colours in the correct order. White or Metallic Gold
(hardest to spread), first; any colour that you have mixed
with White, second; Yellow, Alizarin and Metallic Silver
always last (easily spread). MARBLING: Comb the inks, or use other
methods to create marbled patterns. Then gently lower fabric
onto the ink pattern. The inks should stay on the surface of
the material (similar to screen printing). Should the ink
penetrate through, it indicates that the ink is too thick.
Lift fabric and wash in cold water, keeping it flat at all
times (do not fold or crumple) and then hang to dry. To set
the ink, iron fabric between clean sheets of paper. Before
proceeding with another piece of fabric, skim the surface of
the Carrageen solution with folded newspaper to remove
excess ink, then repeat process. MATERIAL: Solvent based inks are best
suited for marbling on silk, polyester & Poly Cotton
mix. Pure cottons are very difficult to marble using this
type of ink as cotton rapidly absorbs small amounts of
deposited colours leaving fabric white ! The ideal temperature for marbling is
26 C - humidity 60%. The technique of marbling fabric in no
way differs from marbling on paper.

: Marbling size - prepare at least 24
hours before you begin to marbleize to obtain optimum
viscosity. PROCEDURE Mordant solution - used
to prepare the surface of paper or fabric to bond the
pigment. Not to be used on silk or poly cotton
mix. Boiling water 900 ml NOTE: Measure the mordant solution
carefully; a high concentration of alum may cause the
colours to flake off the dried surface and too little alum
will make the colour very light or transparent. MARBLING PROCEDURE; The marbling solution can be reused by
pushing the remaining surface colour to the end of sizing
tray with cardboard and scooping it out.

¨ Controllable viscosity
¨ Suspends colorants on surface
¨ Easy to control and manipulate
patterns
Cold tap: water 1.3 Litter
Carrageen: 1 level tablespoons
Preservative : 5 gr. (1 teaspoon) - Sod.Metabisulfate as
used in home brewing (camden tablet).
¨ Continue mixing until fully dissolved.
¨ Add preservative and mix another 3-5
minutes
¨ Store under refrigeration for at least 24
hours to obtain optimum viscosity and to allow any
entrapped air pockets to rise to the surface.
¨ Test the consistency of the sizing by
pouring a small amount of sizing into a container and
allowing to reach room temperature. Drop some colorant
onto the surface and observe the dispersion property.
¨ If colorant sinks or spreads out too much
the sizing is too thin; add more Carrageen. If he
colorant does not flow easily on the surface the sizing
is too thick and needs to be diluted (add
water).
Alum (ammonium aluminum sulfate) 100 gr.
¨ Pour alum crystals/powder into boiling water
¨ Stir until fully dissolved
¨ Cool to room temperature
¨ Apply cooled solution to the surface of the paper or
fabric with a sponge, or dipping it in the solution.
¨ The treated material should be laid out flat to dry,
although it is easier to work with if it is still
damp.
¨ Gently pour the sizing solution into a marbling tank
to depth of 5 cm. and allow to warm to room temperature
¨ Skim the surface of the size with porous paper to
reduce surface tension and to remove air bubbles and dust
particles.
¨ Suspend colours onto the sizing solution.
¨ Create patterns by combing with a pick, comb, feather
or swirling with flat sticks.
¨ When the desired pattern is obtained, the alum
treated material is slowly and evenly placed on the colours.
If the material is placed on colours quickly, ripples or air
pockets may form and disrupt the pattern.
¨ Patterns are transferred at first contact. As soon as
the surface of the material is marbled lift it at one end
and remove from size
¨ Rinse the sheet or fabric with running water to
remove excess size, or wipe clean with damp sponge.
¨ The marbled item can then be laid out flat or hung to
dry.
¨ Wax or varnish can be applied to the surface of paper
to accentuate the colours and pattern.
Marbling can be very rewarding if using first grade material
with proven practical use. True marbling deposits only 1-3
microns of pigment onto the fiber, and colour must remain
only on one surface. leaving the fabric feel unaltered. If
colour penetrates other side of the material it means that
it is too thick and must be diluted.
Some people under estimate the importance of pure Carrageen
in marbling. Fine sharp definitions and supple handle of
fabric is possible only by using premium grade ingredients.
To come to the point - it is possible to "marble" on mud
however what you use is what you get - mud.
Trying to marbleize with unproved materials can be absolute
hell. You may just as well give it up and take up
knitting!
