WATERVILLE — Two dozen creations by fused glass artists from around the state are on display at Stained Glass Express at 10 Railroad Square.

The works are part of the Gray Glass Challenge exhibit, organized by Waterville glass artists Lucie Boucher and Bernie Huebner of Stone Ridge Glass.

The pieces will be on view to the public from 9 a.m. to 6 p.m. today and 9 a.m. to 5 p.m. Saturday.

Boucher and Huebner launched the Gray Glass Challenge from an idea Boucher got one day while cleaning their studio. They had several boxes — more than 100 pounds worth — of gray glass scraps left over from another project.

They decided to challenge other fused glass artists to take about four pounds of the scrap and make something beautiful.

Artists from places such as Dover-Foxcroft, Bangor, Bucksport, Peaks Island, Poland and Livermore Falls submitted works. Dan Kany, a Portland author on art glass, will judge the pieces at a private event for the artists Saturday night.
