Product Information

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

Available in three sizes -

  • 15mm
  • 22mm
  • 35mm

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.

Due to the manufacturing process, small points may occasionally appear around the edges - these will usually fire out or can be easily removed with a quick grind, diamond hand pad or sickle stone.

An opaque, glossy black, this classic shade melts beautifully for a smooth, uniform surface, ideal for bold, graphic designs and statement jewellery pieces.

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).
