"Infilling missing areas on works of art on paper using papermaking
    pulp dyed to different shades of yellow, red and blue"
Camberwell College of Arts,
Conservation Department,
Wilson Road,
London SE5 8LU
2-3 April 2007

Tutor: Alan Buchanan

Alan Buchanan has developed a methodical visual system to create
matching infills for missing areas in works of art on paper by
dyeing cotton rag papermaking pulp to different shades of yellow,
red and blue.

Eight colour shades are made; six with different depths of shade,
two with different levels of brilliance. Each chart is triangular
and has at its apex a swatch of pure yellow. Below the apex is a
line of two swatches, one is nine parts yellow, plus one part red,
and the other is nine parts yellow and one part blue. The next line
has three swatches: 8y + 2r, 8y + 1r + 1b, 8y + 2b and so on. The
conservator passes the charts over thee work of art with a missing
area and finds the nearest match, for example 1/2% 6y + 2r + 2b.
>From a stock of 1/2% dry dyed pulp he/she takes enough for the
purpose and weighs carefully 6 parts yellow, 2 parts red and 2 parts
blue. These are put into a blender and blended. This takes the pulp
to a close match of the correct tone which can then be finely
adjusted with small additions of the right colours.

The dyeing process will be demonstrated and participants will be
able to dye pulp and draw upon pre-dyed stcok to create matches and
will try out different methods of infilling mising areas on the
vacuum table.

The course is aimed at professional paper conservators.
