We have over 35 years' experience in stained glass conservation ranging from rare medieval panels to large Victorian Studio windows. Working to the CVMA Guidelines and the ICON code of conduct we firmly believe in 'As much as is necessary but as little as possible' in terms of interventive treatments.

Edinburgh Castle

On and off site conservation including improving repairs to Hall; containing edge bonded repairs, specialist cleaning and new lead.

Inverness Town House

A large project with our sister company Rainbow Glass Studios involving all the stained and leaded
glass in the building for Highland Council.
Much of the paint on the Stephen Adams C19 windows had been lost. We have now reinstated a
percentage of this to enable the heraldic shields to be read and understood using a cold paint mixture
pioneered by our two firms and now adopted throughout the UK by fellow conservators.
The windows were refitted as secondary panels with an internally ventilated (Isothermal) system

Hamsterley Hall - County Durham

The images show before and after conservation of two of the large collection of Flemish
17th Century decorated quarries that formed Lord Gort’s Stained glass collection when
the family owned the hall.
Having fallen into disrepair the hall was purchased by Mr Steven Spry and has now been
restored to a high standard.
Iona Art Glass Ltd was engaged to assess and carry out conservation work to the glass
collection involving reinstatement of lost areas, removal of ugly strap leads where
possible and re-setting in new backgrounds using much of the plain antique glass from
the early 20th century installation.
