5. Place the second piece of 1"x 4" glass on top of the first after applying small drop of white glue to the corners to make sure it doesn't slip during firing. Add more confetti as desired.
6. Fire to 1500-degrees to fuse the glass together in the kiln. This process takes about an hour for the firing and then 6 to 8 hours for cooling.
7. After the glass has cooled, then clean. Place the piece back in the kiln over a slump form and heat to about 1250-degrees. When the glass has achieved the desired barrette shape, turn off the kiln and let cool for about 6 to 8 hours.
