Enamel on glass is a jewellery making technique that dates backs to ancient man. You can find detailed examples of enamel jewellery and artefacts in both ancient Greece and ancient Egypt. Cold enamel is a modern technique that mimics the look of vitreous enamel without requiring the use of heat. Cold enamel is a less expensive way to add colour to metal. You can make your own cold enamel jewellery by adding a colourant to epoxy resin and then painting the coloured resin on your metal jewellery findings.

Sketch out your jewellery design. Identify the colours you will need for your cold enamel. Plan where you will place each of the colours you use in your design.
Purchase or create a metal finding that has one or more cells that can be filled with coloured epoxy resin. Cold enamel works best when placed inside a contained cell. The walls of the metal cell need not be very high. Rather, the cell walls need only be high enough to contain the epoxy resin when it is painted and protect the epoxy resin from chipping once the resin is cured. The finding can be made of base metal, sterling silver, vermeil or gold so long as it contains one or more walled cells.
Prepare your metal for the cold enamel by using a two-step process to clean. First, clean the metal with acetone to remove all dirt and grease. Second, rinse the metal with distilled water to be sure all traces of the acetone are gone.
Mix the epoxy resin according to the manufacturer’s instructions.
Add colour to the epoxy resin. If you are using a cold enamel colour kit, then add the colourant according to the manufacturer’s instructions. If you are mixing your own cold enamel colours, then add shavings from eye shadow, pastels, coloured chalk, mica, glass frit or even glass vitreous enamel and stir until the epoxy resin has reached the colour saturation you like.
Pour the coloured epoxy resin into the cell of your metal finding according to your sketch. If unsightly bubbles form when you pour the resin, then you can wave a lighter over the resin or set the resin under a heat lamp to remove the bubbles. Be sure not to place the resin close to the heat source as epoxy resin is flammable.
Allow the resin to cure.
Repeat Steps 4 to 7 until you have added all the colours of cold epoxy resin in your sketched design.
Tips and warnings
- Take proper safety precautions when using jewellery making equipment.
- Always works in a well ventilated area when working with epoxy resin.
- Be sure to wear a dust mask to protect your lungs when working with particulates.
- If you use heat to remove bubbles from the resin, be sure not to allow the heat source to get close to the epoxy resin as epoxy resin is flammable.
