Sometimes bad things happen to good art! This elegant watercolour painting by Canadian artist J. M. Barnsley had suffered water damage in a flooded basement, causing a large disfiguring stain across most of the image.

Luckily, recent stains are often easier to treat than old stains, and when the owners brought it to Book and Paper Conservation Services, we were able to help. 

The process was multi-fold. First, the acidic pulp board backer on the watercolour was removed. This step was painstaking and time-consuming, but necessary before any cleaning could be undertaken. The brown colouring and acidity of the pulp board had leached into the painting when it was exposed to water, causing the staining in the image; it had also caused the paper overall to yellow and deteriorate. Backer boards like this are very common on 19th century watercolours, and this is why we always recommend they be removed as a preservation measure for any work of art on paper.

Once the painting was free of the backer board, it underwent aqueous cleaning in deionized water; this treated not only the overall yellowing of the paper but also began the process of loosening the dark brown staining in the image. After several rinses, the watercolour was air dried, and the results evaluated. Washing had brightened paper tone and significantly reduced the hard brown water stain.

After extensive testing to determine the sensitivity of the pigments and potential reaction of the stain, the final step was to locally apply a chemical bleach to further treat the discolouration. Only solutions that have been tested and approved by conservation scientists are used for chemical bleaching treatments, and only in very controlled applications; the treatment must not leave any trace amounts of chemical, or cause any further damage to the materials. In this case, a very low percentage of a reducing agent was used, and the paper was then rinsed multiple times to remove all chemical residue.

The bleaching treatment further reduced the stain, to the point that it is nearly eliminated. Light losses to the watercolour pigment in areas of mould damage were inpainted to unify the image. The scene can now be appreciated without distraction, and the paper tone is brighter, allowing the colours to appear as the artist intended. 

After conservation treatment, the staining is barely visible, the paper tone is brighter and the image can once more be appreciated without distraction.

An unexpected revelation after treatment was the title of the painting, Gloucester Harbour, handwritten in graphite on the lower left corner of the verso.

The clients selected a new framing scheme for the artwork, and our conservation framing included Japanese tissue hinges adhered with reversible wheat starch paste, acid-free backer and mat board, and GroGlass ARTGLASS 99, offering 99% UV protection. The watercolour painting by J. M. Barnsley is once more looking its best, and is properly preserved for the future. The owners have it displayed in their home once again, and one day will pass it down in their family.  

Conservation framing completes the project with acid-free materials and UV filtering glass.

If you have an artwork that has been damaged by flooding or another catastrophe, don't hesitate to contact us to discuss restoration options. You may think there's little hope to reverse the damage, but it never hurts to get a professional opinion; we're not miracle workers, but quite often conservation treatment can dramatically improve a damaged work of art.

Fine Art Conservation: The Agricultural Art of Ross Butler

Ross Butler was a self-taught artist who made a lasting impression on the agricultural and art communities in Canada and the United States. Working in Woodstock, Ontario, Canada in the mid-20th century, Butler created striking idealized portraits of various breeds of livestock, and his renditions became the standard of measurement for evaluating prize animals.

His works hang in many public and private collections in Canada, but the largest collection of them remains in the possession of the Butler family; his son David maintains the Ross Butler Gallery on the family farm in Woodstock, housed in the barn his father used as a studio during the later part of his lifetime. Being primarily depictions of agricultural life, it is fitting for the works to be displayed in this setting; however, over time the fluctuating environmental conditions in the building have caused some deterioration of the artworks.

The Woodstock Art Gallery recently mounted an exhibition of Butler's work titled Ross Butler: Branding, Butter and Bulls, celebrating the artist's contribution to the community. In advance of the exhibition, Book and Paper Conservation Services was asked to treat several of the major pieces to be displayed.

These two large pastel drawings on paper, titled Ayrshire Bull and Ayrshire Cow, are prime examples of Butler's skill and precision, and were to be featured prominently in the exhibition. However, the paper was suffering severe planar deformation and a sprinkling of mould spots was scattered across the surface of both pieces.

The paper supports had been adhered with wide swaths of adhesive around the edges of the verso to thick masonite backer boards; the tension of this constraint had caused the paper to ripple with the dramatic changes in relative humidity in the barn gallery. To address this the acidic masonite boards were removed from each piece, as well as the adhesive residue on the paper; the artworks were humidified in a controlled humidity chamber and flattened under weight. 

The mould spots on the surface of the pastel media were carefully removed by mechanical means, being careful not to disturb the delicate friable media. Accretions and other debris that had become trapped in the frame were gently removed as well.

The artworks had been framed with care, however the powdery surface of the pastels had been placed directly against the glass, and combined with the rippling of the paper this had caused transfer of the media to the glass.

The final stage of treatment was to clean the original frames and reinstall the artworks with acid-free backer boards, UV filtering glass and spacers to separate the art from the glass and prevent further damage to the media. We do not generally recommend a fixative for pastel media, as the solution can dull the vibrancy of the colour and affect the stability of the piece in the future.

Art Conservation: David Milne Watercolours

David Milne watercolour painting - art conservation

David Milne is one of Canada's most iconic artists, and his sparse, evocative style is seen to great advantage in his watercolour paintings. But as with any art on paper, Milne's works are very susceptible to damage and deterioration. Book and Paper Conservation Services recently restored three David Milne watercolours for the Art Gallery of Windsor

The three works on paper are part of a bequest given to the Gallery by the Estate of Leslie Stibinger, and had not previously been displayed. Moisture and poor storage conditions before acquisition by the gallery had resulted in mould and mildew stains in the paper, as well as mat burn around the perimeter of all three artworks.

The watercolours came to Book and Paper Conservation Services for conservation treatment in the summer of 2017, in advance of the exhibition 'Blazes Along the Trail': Exploring David Milne’s Imaginative Vision, running October 21, 2017 – January 28, 2018. The Gallery was eager to include these three works in the show, but wished to have them restored to their best condition before display. 

The stains in white areas of the paper disfigured the images and distracted from the viewers' appreciation of the composition. The mat burn around the perimeters hindered the works from being displayed to their outermost edges, and the remains of acidic tape and adhesive on the reverse of the works were causing long-term deterioration. These issues were addressed during the restoration of the works.

After extensive testing of the media, paper and stains, a treatment protocol was proposed that included surface cleaning, local stain reduction using chemical bleach, and mechanical removal of the adhesive tape. Over the course of several weeks, the treatments were painstakingly executed to restore the works to Milne's original vision.

The three watercolours have been stabilized and preserved, and now that they are back in the care of the Art Gallery of Windsor, they will remain safe for future generations to enjoy. These works, along with a number of other paintings and prints by Milne, are on display in the exhibition 'Blazes Along the Trail': Exploring David Milne’s Imaginative Vision until January 28, 2018.
