I made the enamel charms by fusing layers of powered glass to copper rectangle with my torch. The 19 mm heart charms are red with black and white frit. The backs are counter-enameled for strength and durability.
Please do not pierce, bend or cut the charms. Enamel is glass and will crack and break away from the copper.
Please note that these are not finished earrings. They are components for you to use in your creations.
