One caution needs to be given before I describe the mechanics of the collodion process. The solvent of collodion is ether; so, lest you anaesthetize your model, it is wise to work in a well ventilated room with an electric fan going.
The major added protuberances are modeled in wads of cotton and tentatively fitted to the face. A coat of collodion is applied with a soft bristle brush at each point where additions are to be made and the cotton is pressed into place. Speed in working is necessary, as the collodion dries rapidly. As each wad of cotton is attached, its outstanding fluffy edges are pressed down to the face with the collodion filled brush. After all the wads are attached to the face, their modeling is adjusted with the fingers. If additional protuberance is needed, it is built onto the cotton already in place with more collodion. With small wisps of cotton, each brushed in place with collodion, the modeling is refined and the large wads are blended into the contours of the face.
In the illustrated instance, The Possessed (Figure 178), the brow was built out large and heavy over the eyes. The nose was built up to meet the line of the brow and was somewhat widened. Additional width was given to the cheekbones, and sundry warts and excrescences were attached. The flabby folds of the neck were also constructed of collodion. Two turkey quills served for the tusks. Collodion and cotton were similarly used in converting the hand into a claw. The long nails were shaped from pieces of old film, and were tied to the fingers before the cotton was applied.
