Product Details

Product Information

Use these 3mm pre-cut black opal ovals to create bold jewellery pieces or add strong contrast to your fused glass designs.

Available in three sizes -

  • 22mm (22mm x 11mm)
  • 35mm (35mm x 17mm)
  • 45mm (45mm x 21mm)

For best results, tack fuse when using as embellishments to help retain their shape. When double layered to 6mm for jewellery, they can be full fused.

Perfect for use with enamels, powders, frit and more, these ready-cut shapes save time while giving a clean, professional finish. Due to the manufacturing process, small points may occasionally appear around the edges - these can be easily removed with a quick grind, diamond hand pad, sickle stone or grozing pliers.

An opaque, glossy black, this classic shade melts beautifully for a smooth, even surface.

Working Note

Cold characteristics:

Consistent colour. Although termed an opal due to its almost total lack of light transmission, this is (in terms of its composition) actually a transparent glass.

Working notes:


Low viscosity. Will flow sooner and more than other glasses. In very thin sections the colour may vary from reddish/grey to
bluish/grey.

All our glass is COE90, Bullseye Glass compatible and suitable for applications such as glass fusing, glass casting and glass slumping (unless otherwise stated in the description).
