Shanna Kaczynski, Sarah Ripp and Kathyrn Petke have been collaborating on sheet formation. Kathyrn brought in some puffy plants which I think are called Chinese lantern flowers or maybe they are Bougainvillea. Shanna harvested some dill will. There is no shortage of wild dill weed in Wisconsin during the summer. Sarah Ripp provided some white cotton fiber. The plants were dried under pressure for several days and added to beaten pulp in the vat during the formation process. The result are sheets with randomly placed dried plant matter on a white sheet. The Bougainvillea have lost some color but the texture and shape add visual interest to the sheet.

Often, in class, the question is posed. “Is this pulp beaten enough?” Often my reply is, “It depends” In Andrea Brdek’s case, this pulp is almost ready for what she wants to do.

These instructions were included in the shipment of Retention aid.

Carriage House Retention Aid is a cationic poly(arnine) specifically manufactured for the retention of pigments, dyes and other fillers in paper pulp.

Directions for using retention aid

Please note that all pigments, dyes, and other chemicals should be handled with care. For more information as to the proper precautions in working with art materials, contact: Cent for Occupational Hazards, 7 Beekman St., New York, NY 10038. The Center has several detailed publications on this important subject.

Use and Instructions:

Retention Aid is used by first making a stock solution. This is then measured out for use and diluted further before adding to the pulp. The dry powder has an indefinite shelf life. The mixed solution is best used within one or two days, but will store longer under most conditions.

Making stock solution:

The stock solution is made by mixing the dry powder with water to make a concentrated solution. To allow the solution to mix properly, it is best to make it the night before it is needed, though in most circumstances a solution free of lumps can be made within an hour. The ratio of the powder to the water is 1 tsp. powder per 1 pt. of water. Slowly add the powder to the water while mixing, until all powder is into solution. If necessary, use a blender to break up the clumps.

Use of stock solution:

The stock solution must first be diluted with 1 gal. of water before it is added directly to the pulp to allow for even dispersion. Add your pigment to the pulp. Once you have the color you want, slowly begin adding the retention aid solution. Continue to add until the pigment is retained.

Use with sizing:

If you are using sizing, the order for mixing is: pigment, retention aid, sizing. Allow about 5 min. between steps for proper mixing.

A resent observation. A student was using pigment to add color to the cotton fiber. She added too much pigment to the pulp. When she squeezed the pulp to, she noticed that alot of the yellow ran out. When this happens, you need to rinse the pulp. Do not add more retention agent as that will not keep the pigment from running out. Adding more retention agent is not going to keep the pigment in the pulp. It is simply over saturated with pgiment. Rinse the pulp with fresh water to flush out the excess pigment prior to forming the sheets. Not rinsing it will stain all the felts. It is best to be safe and wear rubber gloves when flushing out the pigment if you think it is at excess levels.

Using Soda Ash – Use eye protection and rubber gloves.
USE: Cooking raw fiber to prepare for papermaking.
COOKING INSTRUCTIONS: For fibers such as Kozo, use 4 to 5 ounces per pound of dry fiber. Cook in a stainless steel or enameled steel pot NOT IN an aluminum pot, .
PRECAUTIONS: Soda Ash is considered mild, but it a caustic and requires careful handling. All alkali chemicals should be added to water, never add water to an alkali as spattering can occur; wear eye protection. It rarely irritates the skin, but can cause drying and cracking; wear rubber gloves.
