Large domestic etched door (Linda)

Glasgow, West End

This large etched door had been accidentally hit by a scaffold pole. It broke into hundreds of tiny pieces.

Broken glass

Fortunately, the neighbour's door was intact. Thin paper was stretched over the neighbour's dore, and detailed rubbings were made.


A very large jigsaw was then constructed on top of the rubbing using the broken glass fragments. It was easy to see exactly where the impact had occurred.


A new sheet of 10mm glass was placed on top of the rubbing, and a new cartoon was carefully cut out of fablon, drawn on the surface.

Cutting the trace

The glass sheet was then fed slowly through a sandblast cabinet to deeply etch the design into the glass.

First sandblast

Some of the fablon was removed, and the glass was fed through the sandblaster for a second time.

Second sandblast

A final layer of sandblasting, creating an image made out of different textured layers within the glass.

Third sandblast

The size of the glass is approximately 3' wide x 6' high. Here the glass is being fed through the industrial sandblaster.

Drawing through

After each sandblast, a layer of fablon is carefully removed.

Removing the fablon

A transparent glass enamel is lightly painted into the deep grooves.

Painting the clear enamel

This process is painstakingly slow. No enamel must be allowed onto the flat surface of the glass.

Painting the clear enamel

The finished painting is exquisitely detailed.

Painting the clear enamel

The clear enamel is white before firing, but turns completely clear around 700 degrees Celsius.

Firing the glass
