I was gifted some beautiful looking shards and finally made some owls using them. Shards are made by winding molten glass around the end of a tube in a rough bowl shape then blowing through the tube so that it forms a thinned bulb shape. When solidified you smash the bulb, producing 'shards' of glass. These shards have some silvered ivory in the mix which provides a lovely organic effect. Here's a photo with the shards before they're applied, they are very thin, fragile and razor sharp!
Here are the owls finished. I used a white base. Verdict? I like. The last owl has some frit of silver glass Terranova on his back, which has turned the shard a deeper golden-brown hue.
