OPALS are a new generation of thick embossing enamels, made in rich opalescent colours, which can be used for all sorts of projects.  They make wonderful tiles, gorgeous seals, fabulous jewellery and amazing 3D items.  Opals will work on any surface which will take heat, including cardstock, wood, latex moulds and glass.  They are beautiful left smooth and fantastic when a stamp is pressed in to give texture.
