Pastel Portrait

Since the advent of photography, the popularity of hand drawn or painted portraits has slowly dwindled. They are considered old fashioned or a novelty and have been phased out in most of our homes. A few weeks ago, however, a client brought in a pastel portrait of his brother that was drawn at Pacific Ocean Park in Santa Monica in 1961, the subject was 9 years old at the time. The glass in the frame had been broken and had damaged part of the drawing.

The portrait had a tear through the upper left corner. In addition there was some discoloration due to oxidation visible throughout the background. The mat board had protected the areas that were still grey, the original paper color, but the rest of the paper had oxidized. The condition of the paper was a factor that we had to take into account during the mounting and restoration processes.

  We applied a fixative to the existing pigments before beginning the mounting procedure, but because of the mobile nature of chalk pastels pigments we still proceeded with caution. Normally with pieces where the medium is unstable we use the resizing technique that John developed. However, this was not a good option with this piece because the paper was very porous and we were worried that this might cause more damage. Our goal is always to preserve the integrity of the piece through both the conservation and restoration processes.

Melissa worked under John's direction during the conservation process. The piece was mounted so that she could fix the tear and then apply pastel over the top so that the piece would look as good as new by the end.

Once the piece had been sprayed with fixative, the pastels pigments were stable enough for us to carefully  mount it.

Once the piece had been sprayed and was face down on the glass table, the Mylar was removed from the back. Then glue was applied to the back of the piece. We carefully wiped away any excess water and glue from the Mylar underneath the paper so that only the paper would stick to the substrate.

 After the glue had been applied the piece was mounted to an Okawara paper substrate on a melamine board. This provided a stable surface for the piece and for Melissa to work on.

Pictured: Tears in the paper from the back. The paper that was torn now lays relatively flat, however, the tear is still clearly visible.

With the piece gently resting on top of the paper the next step was to apply pressure evenly across the surface to join the paper of the portrait to the Okawara substrate.

Once the piece is mounted to the substrate and melamine board it needs to dry. After it has dried completely Melissa began to restore the damaged area. She started by repairing the tear lines. She used a combination of glue and filler to restore the damage before burnishing and smoothing the lines down.

Once the glue and the filler had dried, Melissa was then able to go back in with pastels and restore the image that had been damaged by the tear. She carefully layered the pastels over the repaired area so that it matched the existing color.

Once Melissa had finished restoring the piece, all that remained was for it to be removed from the melamine board. A thin knife was inserted between the board and the Okawara paper to demount it from the board, but the piece remains mounted to the Okawara substrate.

Tadaaa! No sign of the tear in the upper left corner remains!



Melissa took the wheel on this project, so she also got to hand the piece over to the client. And of course we needed to capture that moment!
