Decals can be used to embellish pendants or add accents to your glass projects. Easily applied by soaking in water (preferably distilled water, to avoid mineral contamination) until the decal starts to separate from the backing paper. Carefully peel off the backing and 'slide' the decal into place, using a squeegee to smooth out the decal on the glass (an old credit card works well), and to push out any trapped air bubbles. If 'sandwiching' the decal, it is often best to fuse the decal first, then top with glass and re fire.
Decals do not have a CoE and can therefore be used with all types of glass.
