Tree of Life Stained Glass
The phases of the moon adorn the branches of the tree, which portray the seasons of the earth. If you look closely , the wintry branches are made with flashed glass. Flashed glass is a process where colored glass is introduced to molten glass and the two pieces meld and become one. Then the glass is masked off in the areas to keep the color, and the glass is sand blasted to reveal the white wintry branch.
