Because refrigeration may cause the paste to lose its tack, keep it at room temperature. It is best to make small batches, since the paste does not usually keep for more than a week. A preservative can be added, Recover Documents From Smoke Damage but these chemicals are toxic and not recommended.

Microwave Wheat Starch Paste University Products, a supplier of conservation materials, publishes a quick, easy paste recipe in its catalog. This Recover Documents From Smoke Damage is ideal if paste is used only occasionally and in small quantities. Strain and dilute the paste beofre use, as above.

Place 1 tablespoon of wheat starch in a clean, microwave-safe container, add 5 tablespoons of distilled water, stir, and place the mixture in a microwave oven. Microwave on a high setting 20 to 30 seconds, remove the Recover Documents From Smoke Damage paste, and stir. Place it back in the unit and microwave it another 20 to 30 seconds.

Remove it and stir Recover Documents From Smoke Damage again. Repeat this process several times until the paste is stiff and translucent. If larger quantities are made in the microwave oven, increase the cooking time between stirrings. Paste should be cooled to room temperature before it is strained and diluted for use.

Another Simple Recover Documents From Smoke DamagePaste: Methyl cellulose, the main ingredient in most commercial wallpaper pastes, is acceptable for conservation purposes if used in its pure form. It is available from conservation suppliers as a white powder and does not need to be cooked.

Add 1 rounded tablespoon of methyl cellulose powder to 1/2 cup distilled water, stir, and let stand for several hours. Thin to the consistency of mayonnaise with distilled water. Methyl cellulose absorbs water slowly so Recover Documents From Smoke Damage dilution takes a few minutes. Methyl cellulose is not as strong as starch paste but should give adequate support for objects of moderate size. 
It keeps for several weeks and does not require Recover Documents From Smoke Damage refrigeration.

THE HINGING PROCEDURE

Before hinging, assemble the following: The finished window mat Hinging paper (Japanesekozo) torn or cut in appropriate sizes Starch paste in a small dish, thinned to the consistency of mayonnaise A flat artist’s brush, ideally 3/8 to 1/2 inch wide Pieces of clean, white blotter, about 2 by 3 inches.

A larger Recover Documents From Smoke Damage blotter to serve as a substrate for pasting Small pieces of spun polyester (Hollytex or Reemay), the same size as the blotter pieces. Spun polyester is available from conservation suppliers. Several weights, at least one pound each (two pounds is better). Lead weights with a flat surface can be covered with cloth. Fishing weights or bags of lead shot can also be used on top of small pieces of glass or Recover Documents From Smoke Damage rigid acrylic. 

Archival tape for securing the top of the hinge to the Recover Documents From Smoke Damage backboard (for example, Lineco Framing/Hinging Gummed Paper Tape) Tweezers or other implement for handling pasted wet hinges Attaching the Hinges

1. Make the mat first. Attach the window portion of the mat to the backboard with a strip of cloth tape so that the window and backboard are aligned.

2. Place the object to be matted face down on a clean surface.

3. If pendant hinges are used, brush starch paste on one edge of the Recover Documents From Smoke Damage tab (the part that will adhere to the reverse of the object) on a piece of blotting paper to absorb excess moisture. Apply the hinge to the reverse of the object and, once in place, tamp it lightly with blotting paper or other absorbent material to further remove excess moisture.

Place a piece of nonwoven polyester (Hollytex or Reemay) to prevent sticking and then a small blotter and weight over the hinge and leave until the Recover Documents From Smoke Damage hinge, is completely dry. 

Changing the Recover Documents From Smoke Damage blotter after the first few minutes will speed the process as will drying the blotters for a few seconds in a microwave oven before using them. This also reduces the risk of cockling or staining the paper because of moisture. Allow at least one hour under weight for hinges to dry completely.

4. Repeat the application of hinges wherever needed, always at the upper corners at least.

5. Place the Recover Documents From Smoke Damage object face up on the mat backboard and check that it is centered in the window. Weight the object so it does not move. Be sure to protect the face of the object with a piece of blotter under the weight.

6. Open the mat and attach the top of each hinge to the backboard as shown in Figure 2. In the case of folded-under hinges, small pieces of Recover Documents From Smoke Damage polyester or Melinex should be placed inside the hinge to keep it from adhering to itself during drying. 

Weight the Recover Documents From Smoke Damage hinges as before for a good hour until they are completely dry. Remove the inserted polyester or Melinex pieces. It may take time before hinging comes easily, but practice pays off. Mounting without Hinges In recent years some institutions have been reluctant to apply adhesives to artifacts, especially if they are valuable.

Mounting without adhesives can be done with corner supports or Recover Documents From Smoke Damage edge strips. Small corners of chemically stable plastic (polyester film) or archival paper are commercially available for mounting photographs. Although photo corners work well for many photographs and for small works on paper, they are too small to support larger objects.

Larger envelope corners (made from folded paper) or strips across the corners give better support, but they cannot be hidden under the mat unless the Recover Documents From Smoke Damage object has wide margins. 

Hugh Phibbs, coordinator of matting and framing services at the National Gallery of Art in Washington, D.C., has developed innovative Recover Documents From Smoke Damage ways of mounting without adhesives. Generally speaking, these methods involve supporting the object on the mat with strips of archival-quality paper that are folded over the edges of the object to hold it in place.

The strips are adhered to the backboard at their extremities. Phibbs gives workshops periodically, and his ideas appear in a monthly column in Picture Framing Magazine. Some of these articles are cited below. Most of the following Recover Documents From Smoke Damage procedures should be performed by a professional conservator who specializes in the treatment of paper.

This leaflet describes some of the principal operations carried out by paper conservators. The treatment chosen for any artifact or collection should be the outcome of communication between a conservator and the client or custodian after the conservator has examined the Recover Documents From Smoke Damageartifact.
