I created this unique cobalt blue sun catcher by cutting the bottom off of a blue bottle and placing it on top of a mold in the kiln and firing it to 1520 degrees Fahrenheit . The bottle melts down into the cavity and a sun catcher is born. I glued a pendant bail onto the back of this piece so that it can be hung wherever you desire. I have several of these in stock so the one in the picture might not be the one you receive but they are all very similar and all blue. I do offer this item in various colors and designs so be sure to check out the rest of my items. Diameter approx. 2 1/4" to 2 3/4"
