This is a torch fired enamel bar penant. The pendant is rectangular with a curved top.
The back of the pendant is blackened due to the firing process (pointing a blow torch at it until the glass melts!). The edges have been renaissance waxed to preserve the colour of the darkened copper. The pendant is very slightly bent to sit more comfortably (not noticable from the front). The purple is a gradient, darker at the bottom and just a dusting at the top. The surface is irregular to achieve a speckly effect.
The pendant is 4cm high and 8mm wide.
The chain is a light trace chain. It's currently 40cm (16") but can be swapped for a longer chain if needed.
