For more than two centuries, these companion portraits of Isabelle and John had remained together. Believed to have been painted in Edinburgh around 1815, they reflect the elegance of Regency portraiture, with finely handled features, a restrained palette and a sense of formality associated with the British portraiture of the era.
When our client contacted first contacted us, his aim was not to make the paintings look new, but to preserve history. Past damage, discoloured varnish and old repairs had gradually disrupted their appearance, including abrasions reportedly caused decades ago.

Professional painting conservation offered a way to stabilise the portraits, recover their clarity and ensure Isabelle and John could continue to be appreciated into the future. If you have an antique painting in need of assessment, our conservation team can advise on the safest and most appropriate treatment.

Preserved on Canvas
Pendant portraits such as these were an important part of domestic life during the regency period. Commissioned to celebrate marriage, family status or inheritance, they were designed to hang together, balancing one another visually while recording the likenesses of husband and wife, brother and sister, father and daughter for future generations.
Unlike grand state portraits, works of this type often remained within the same family for centuries. Their significance lies not simply in artistic quality but in the personal histories they continue to represent. Painting conservation therefore focused on preserving originality wherever possible while carefully reversing deterioration that had gradually obscured the artist’s work.
Looking Beyond Surface Damage
Although both portraits were structurally stable, closer examination revealed that previous restoration was now contributing to the visual disruption of the paintings.

Older restoration can fail for several reasons. Retouched pigments and patches of new varnish often age at a different rate from original oil paint, causing once-subtle repairs to darken, become matte, discolour or sit visibly on the surface. Historic overpaint may also extend beyond the actual area of damage, concealing original detail beneath. In some cases, earlier repairs were carried out with materials that are no longer considered conservation-appropriate, making them less stable and harder to integrate over time.
The portrait of John displayed widespread age-related craquelure, two pronounced abrasions along the lower edge and earlier retouching across the face that had become matte and visually distracting. An increasingly hazy varnish and decades of accumulated surface dirt had muted the painting’s depth and tonal range.

The portrait of Isabelle presented similar challenges. Historic retouching across the neck, face and rich crimson drapery had aged differently from the original paint, while scattered losses, pronounced craquelure and degraded varnish interrupted the elegance of the composition. Dust had also accumulated across both the front and reverse of each canvas after years in a domestic environment.

Rather than treating only the most obvious defects, every intervention was planned to improve the visual unity of the pair while preserving as much original material as possible.
Conservation, Not Reinvention
Following extensive examination and cleaning tests, treatment began with thorough documentation before both paintings underwent careful stabilisation and consolidation where vulnerable paint required support.

Surface dirt was removed using tailored conservation cleaning systems before conservators gradually reduced the aged varnish that had dulled the colours for many decades. Solvent testing ensured each stage remained appropriate for the original paint layers, particularly within the more sensitive red pigments.
Historic overpaint was reduced where appropriate, allowing earlier restorations to blend more sympathetically with the surrounding original paint. Areas of abrasion and paint loss were then carefully reintegrated using fully reversible conservation materials before a final conservation-grade varnish restored depth, saturation and long-term protection.

Throughout treatment, the objective remained consistent: preserve authenticity while allowing the portraits to be appreciated much as their original artist intended.
Restoring Clarity & Balance
As layers of discoloured varnish were removed, subtle modelling within the faces re-emerged, black clothing regained richness and depth, while the dramatic red drapery behind each sitter once again provided the visual contrast originally intended by the artist.

Most importantly, the paintings once again read as a true pair. The shared palette, balance and presence, which had gradually become separated by ageing varnish and earlier repairs, were reunited through careful conservation rather than excessive restoration.
After seeing the completed work, our client wrote:
“The restored paintings look really great with the colours much more vibrant – the features of Isabelle and John looking both clear and defined.”

Conserving Historic Portraits
Historic portraits often carry significance that extends well beyond their artistic value. Whether depicting generations of one family, recording an important commission or forming part of a historic collection, careful conservation ensures these works continue to survive while retaining their authenticity.
Our easel painting conservators provide:
- Detailed condition assessments and conservation reporting.
- Cleaning to remove discoloured varnish and accumulated surface contamination.
- Stabilisation of fragile paint layers and structural repairs.
- Sensitive retouching using fully reversible conservation materials.
- Conservation framing advice for historically appropriate presentation.
- Nationwide collection and delivery throughout the UK.
Whether your portrait requires routine conservation or extensive restoration following historic damage, our team can advise on the most appropriate treatment to preserve both its appearance and its history for future generations.
