Conservator Linda Waters, and her colleague Tijana Cvetkovic, have been helping Bronwyn Holloway-Smith of the Mural Search and Recovery Project investigate whether a 1960s mural by Mervyn E Taylor called ‘First Kumara Planting’ ’ is still intact, hidden under white paint in the old Soil Bureau building in Taita.
The story so far
In my previous post I described how we used infra-red technology to attempt to see through the paint over the mural on site.
It soon became clear this wouldn’t be possible due to the nature of the artist’s paint and the house-paint over the mural.
So we then decided to take a tiny sample from the wall to put under the microscope to see if this technique yielded more results in seeing paint from the original mural. This proved a success!
Taking further paint samples
We now wanted to get an indication of whether the mural was there in its entirety so we went back for a second visit and took samples from elsewhere on the wall.
We had suggested that Bronwyn map out where the edges of the mural were expected to be using an old photograph as a reference. She had done this, so we could then aim, albeit approximately, for particular areas to sample.
We took one from the extreme left, and one from each of the top and the bottom. Our initial sample taken on the first visit had come from the right side, so there was no need to take another from there.



Results
Here are the results, with which we’re very happy, as it means the mural is likely there, complete, on the wall…you can see, under the two layers of white paint, blue, yellow and red paint artist’s paint from the different areas.
This strong blue is from the top of the mural.

There is bright yellow at the bottom, which may have line work on top of it related to the foliage seen in that area.

The red ‘ochre’ (descriptive of the colour, not ochre per se) is from the two figures and their implements on the left of the mural.

Mural recovery?
Unfortunately the mural cannot be easily uncovered, either chemically with solvents or mechanically with scalpels.
Essentially this is due to the nature of the materials and the uneven concrete substrate.
The artist’s paint layer is very thin compared to the layers above it, and it sits on a rather textured, sort of pitted, concrete substrate; because of this mechanical removal would result in damage to the original paint and a very unsatisfactory incomplete or uneven finish.
The use of solvents, too, would most likely affect both paint layers – the white paint over the mural and the artist’s paint are very similar, so solvent work to remove them would very likely damage the artist’s paint below.
This is fascinating. I always loved Mervyn Taylor’s work and I used to work with his son Terrance Taylor at Learning media some years ago. His clear graphic style and strong colour akin to his wood cuts was something I always admired as an artist myself. It would be a wonderful thing to be able to restore this mural somehow albeit a difficult task.
Hi Simon,
It is exciting, and Mervyn’s designs are so stunning, I agree! We’ve enjoyed being able to assist Bronwyn in establishing the presence of the mural at Taita. Unfortunately it is not really possible to recover it, as the combination of materials on the wall, those of the artist, and the irregular concrete substrate really do dictate against a good outcome.
