Youghiogheny Gray Cobalt Opal Fusible Glass 96 COE

Note: glass must strike to reach target color. Unfired sheets may appear somewhat translucent.

Due to a variety of firing schedules customers may experience surface devitrification on the Youghiogheny opal product line.

We recommend you cap the opal glass with clear fusible glass or use Hotline's Spray A Plus or Fuse Master Super Spray to reduce the possibility of devitrification.
