Painted glass

Firstly, and more correctly, it means enamelled glass, normally relatively small vessels which have been painted with preparations of vitreous enamel, and then fixed by a light firing to melt them and fuse them to the glass surface.

Here the design is made up using sheets of coloured glass, cut to shape and held in place by lead.

The painting is the final stage, typically only in black.

There is benefits to glass painting, it adds depth and texture, reflects light, easy to clean and maintain, and it creates a focal point.

Providing a look of a fairy-tale and when sunlight shines through, it amplifies its beauty.
