Create sparkling icicles for Christmas trees and holiday windows with this unique design. They are extremely easy-to-make. Just fill the body with coarse frit and the ring with medium frit and fire. Three or four make a perfect holiday project for instructors and students or as a small gift for friends and colleagues. The finished icicles range from 4.25 to 5 inches (10.5 to 12.5 cm) long. The mold is 6.5 by 6.5 inches (17 x 17 cm) and the cavities hold 17 to 24 grams of frit. Make sure to follow the special firing schedule outlined in the project sheet.
