eco printing on paper
Materials list
Heat Source — Hot plate, stove, or camp stove using propane. (WA32082)
Large Pot or Steamer — You will want this pot to be dedicated to eco printing and nothing else. To save money, purchase one from a thrift store. The larger the better.
Paper — Watercolor paper will work best, but any paper can be used. You will need 10 sheets or an accordion folded bunch per student if they are making a book. Paper should be cut to the size of the wood blocks or tiles used. (9701004 or 9716081)
Spray bottles filled with hot water and 1 tablespoon each of Alum and Copper Sulfate — One spray bottle per table is usually enough.

Alum (SA09334)
Copper Sulfate (SB07680)

Pieces of wood or tiles — Two per student to “sandwich” bundles before steaming or simmering. Ferrous sulfate (iron) — All leaves will be dipped in iron solution prior to placing on paper, vein side touching paper. If you use ferrous sulfate, dilute 1 teaspoon per 2 cups of water. You can also make a homemade iron solution using rusty metal in vinegar that soaks for 2 weeks in a plastic container.
Vinegar — Use white distilled vinegar in plastic containers for dipping red cabbage, onion skins, purple carrots, beets or eucalyptus.
Rusty objects — Use washers, keys, door hinges, or any flat piece of metal that can be layered into your “sandwich” and used to enhance your prints.
Vegetables — Canned beets, red cabbage, yellow onion skins, purple carrots and eucalyptus is optional. You will also need a knife to slice these ahead of time.
Personal protective equipment — Rubber gloves for the instructor, vinyl gloves for students, and if room is not ventilated, a face mask for each student may be necessary due to the strong smells of the iron water. (C20030)
Cotton twine — Several spools to tie wood or tiles together. (K00129)
Scissors — To cut twine. (9731962)
Masking Tape — You will only need masking tape to label your bundles. Before steaming your bundles, everyone should write their name with a pen or permanent marker and tape it on the twine. (9740906)
Leaves — Gather leaves with students or gather them ahead of time. Try to choose a variety of oak, maple, sweet gum, sumac (not poison), walnut, and fruit/flower/nut bearing trees. Each one will produce a print.
Other items for color — Onion skins, walnuts, acorns and various teas that have fruits in them.
