This bright glass starts life as a rectangular hand-cut piece of clear artisan glass. Different coloured glass is then cut and placed on top to finish the effect before firing in a kiln at approx. 800℃ to fuse all the elements together. Approx. 24cm x 8cm As each glass element is handmade, no two are the same, so the wave you receive may not be exactly the same as the one pictured.
