805. Washing

Washing. After fixing, the cards should be washed by placing them on an inclined piece of glass; then with a rubber hose spray the cards for a few minutes, spraying both sides. After five minutes washing the prints can be dried in the following manner:

806. Quick Drying Box

Quick Drying Box. Construct a box or cupboard of fairly good size - say, 3x4 feet - with a cover or door which can be let down. An ordinary large packing case will answer the purpose very well. To two sides of the box nail strips of wood about six to eight inches apart, these strips serving as supports for the stretchers on which the cards are to be laid. Construct a number of stretchers, to fit into the box so that they can be slid in and out on the supporting strips, and cover them with cheese-cloth.

807. Although requiring longer time to construct them, a better form of stretcher can be made by interlacing white twine across the stretcher, much in the same way as a tennis racket is made. The cards will dry quicker than when laid on cheese-cloth.

808. The drying box should be built about two feet from the floor. The door of the box should be made to drop down and form a table. Cover the inside of the door with two layers of clean, pure blotters and over this tack a sheet of cheese-cloth. When the cards are taken from the wash water, lay them face up on the door, and with a strip of clean cheese-cloth wipe off the moisture from the face; then place the cards, face down, on the stretchers, to dry.

809. Cut a large hole in the bottom of the box and cover the opening with a sheet of perforated metal - zinc or sheet iron. Under this set a lamp, the heat from which will rise and circulate between the stretchers and dry the cards very quickly. A large funnel over the lamp will materially assist in collecting the heat rays.

810. Where the arrangements of the gallery will permit, it will facilitate handling of the cards if the drying box is built with the back of the box facing the office, so that it can be reached from the business counter. A second door in the box, constructed to open from the counter, is then used to take out the dry cards, which avoids running to and fro from the dark-room.

811. Overcoming Abrasion Marks

Overcoming Abrasion Marks. Abrasion marks frequently appear on post-cards, especially where a vignette or mask has been used. This you can overcome by adding ten grains of iodide of potassium to each fluid ounce of developer. These abrasion marks can also be removed from the cards or prints after they become dry (and only after they have become dry) by rubbing with a soft cloth or tuft of absorbent cotton dampened with wood alcohol.

812. Preparing The Celluloid Film

Preparing The Celluloid Film. In order that the celluloid will lay out flat without buckling or cockling, it should be placed for one hour in glycerin. The glycerin will make it very soft and pliable. The celluloid must, however, be allowed to dry before placing it in contact with your wet negatives.
