Jon Callan, an independent glass artist, established his Dorchester based studio in 1981 after training in traditional glass painting, heraldry & contemporary glass design at the Architectural Glass department at Swansea college of Art. Since then the studio has built up an extensive client base, including the Church, architects, surveyors, builders, commercial organisations and private individuals.


Restoration & Conservation

The idea of conserving something as modern as 20th-century windows might seem totally unnecessary. But, like many other objects, relatively new windows can fail and decay, especially due to the use of post-war materials like polymer based resins, and processes, such as Dalle de Verre (slab glass set in concrete or resin), glass appliqué, glass fusing and glass printing.

20th-Century Conservation

Conserving 20th-century windows brings with them their own special requirements and need the same careful recording, analytical consideration and detailed enquiry as other historic artefacts.

Repairs and Restoration

A repair may be a straightforward in situ replacement of a single pane of glass, or the removal to the workshop of a part or complete window for reglazing and releading.

Cracks can be joined with thin leads, or edge bonded, with lost areas reinterpreted with new sympathetically painted glass.

The window was smashed by a falling tree in 1987, and restored in 2012.

Prior to the commencement of any intervention to a window a full working methodology based upon the Corpus Vitreanum (CVMA) guidelines is agreed with the client.
