Brooches by John Field This design is a revisiting of a concept, first developed by me in around 1990, for which Tony coined the phrase “Urban Survival Kits”. The idea is that earrings to be worn after work could be held safe throughout the day in a box, which itself may be a pendant or in this case a brooch, ready for a transformation for the evening ahead.The stripy silver brooch lid opens to reveal earrings featuring the same pattern. Underneath these is a circular recess in the wooden layer that holds the ear wires.The main techniques used in the making of the piece include roller printing, piercing, wood turning and soldering. A combination of some, or all of these techniques, have been used in just about every piece that I have made since graduating in 1987.View all the 40 brooches for 40 years exhibition.
