This colbalt blue waterglass was cut and ground and fired in my kiln to slump it into this shape. It measures approximately 4 1/2" tall and is 6" wide. These pieces can be used for many things other than a candleholder or a vase. Each one is different. Because they are fired and melted in the kiln there is no way to control how they melt. I can sign and date on bottom if you would like.
