The traditional vitreous (Latin ‘vitreum’ means glass) enamelling dates back to the 13th century BC. Coloured glass powders are carefully applied onto a base, usually metal, and fused by heat into a strong luminous surface. From the 19th century, enamel began to be used industrially: A liquid glass mix is fired in huge kilns to form a durable coating for everyday domestic wares such as our familiar bathtubs and fridge doors. I work with both traditional and liquid enamels, moving between shifting, painting, drawing and using decals (images) fired into the glass.
