Oceanside Compatible sheet glass is designed and tested so that the products "fit" with each other in warm and hot glass applications. Opalescent glass is mostly opaque, yet may display a muted, luminescent glow when backlit (varies by product). Whether a colorful or neutral hue, the rich tones of opalescent glass are a staple in every glass palette. Sheet glass can be used for stained glass, mosaic art and mixed media projects.Details:Available in multiple colors12" x 12" sheet size3 mm thicknessOpalescentSmoothFusible
