Cyanotype Set - JACQUARD

Cyanotype Set - JACQUARD

For photographic blueprints on paper and fabric.

Cyanotype is the original sun-printing process, one of the earliest photographic techniques. Harness the power of the sun to make detailed prints from virtually any object that casts a shadow. Simply place the object on the sensitized surface and expose to sunlight (UV). Use a digitally-printed photographic negative instead of an object to create full-resolution photographs on paper or fabric.

Great for photographers, mixed media artists, printmakers, quilters, kids and more, the cyanotype process is easy, forgiving, quick, magical and fun.

This package contains one 0.8oz bottle of Potassium Ferricyanide and one 1,9oz bottle of Ferric Ammonium Citrate.
Made in the USA.

Contents:
Part A (Potassium Ferricyanide) & Part B (Ferric Ammonium Citrate)

This set contains enough chemistry to make approximately sixty-five, 8"x10" prints on paper or forty, 8"x10" prints on fabric, depending on the absorbency of the substrate.

Instructions:

• Fill both containers with water to create Stock Solutions A & B. Shake until powder is fully dissolved. For best results, wait 24 hours before using. Stock Solutions have a long shelf life.
• In subdued lighting, mix equal parts SOLUTION A and SOLUTION B to create the cyanotype sensitizer. Mix only the amount you immediately need, as the sensitizer is stable just 2-4 hours.
• Coat paper or fabric with the sensitizer and allow to air dry in the dark.
• Once dry, make exposures in sunlight (1-30 minutes, depending on conditions) or under a UV light source, placing objects or a film negative on the coated surface to create an image. (Note: over-exposure is generally preferred to under-exposure. The print should look bronze in color after an adequate exposure).
• Process prints in a tray of cool water. Wash for at least 5 minutes and allow to air dry. During washing and drying, cyanotypes will slowly oxidize to their final, deep blue color. To quicken this process, submerge washed prints in a dilute solution of hydrogen peroxide.

Notes:

• The cyanotype process was developed by Sir John Herschel in 1842. Jacquard's Cyanotype Set utilizes the exact same formula Herschel used.
• The cyanotype reaction produces a cyan-blue pigment, ferric ferricyanide (also known as Prussian blue), a pigment found in many high-end watercolors, oil & acrylic paints.
• Cyanotype prints are archival. If exposed to phosphates or high pH environments, however, yellowing may occur. Cyanotype fabrics should always be laundered using non-phosphate detergents, therefore, and prints should be handled with care, as sweat and hand oils may also cause discoloration.
• There are many methods for toning and altering cyanotype prints using simple post treatments and common household reagents such as baking soda or black tea. For more information, visit www.JacquardProducts.com.
• CAUTION: May cause skin, eye, or respiratory track irritation. Avoid contact with skin, clothing, or inhaling dust. If inhaled move to fresh air. In case of contact with skin or eyes rinse with water for 15 minutes.
