This unique Northern Lights Art Panel is an image embedded in streaky glass (Dark Forest Green with Yellow Opal). Making a piece like this involves a several step process involving heat (kiln fired) and sandblasting. This art panel is not sealed; sealing it helps reduce the appearance of fingerprints, but it can be easily cleaned with soap and water. There is a risk in heat sealing that can diminish the contrast between the high gloss image and the matte glass. Another option is to seal the art panel with a polymer based product. If you would like the piece sealed with heat or polymer, simply communicate that in your order. There will be an additional $12 fee for sealing. This handmade Northern Lights art panel measures approximately 8” wide x 7 7/8” tall.
