Manetti 23 Karat Glass Gold differs than Patent Gold because it is not adhered to a thin tissue. Its name originates from its use on Glass Doors and Glass Windows. Glass Gold must be handled with the use of a Gilders Tip. Glass Gold Leaf is ideal for application onto textured artwork because it can be gently pushed into the cracks, and crevices with a soft camel hair brush. The leaves are 3-3/8" x 3-3/8" and sold 25 per book.
