GLASS DECORATION COLORS
These colors are being used in fusion technique that means high temperature firing of glass, including forming, for decoration purposes. When correctly used they give very attractive and bright colors matchable with glass. They can be used either over the glass plate or between two glass plates.
Fusion colors are of two types which are bubbling colors and plain colors.
Bubbling colors are applied between the glass plates and when fired a bubbly appearance comes out. The size of the bubbles changes with the quantity of color. In order to get an even distribution of bubbles, applied color quantity should be almost the same all over the surface.
Bubbling colors are transparent and some of them can be used on glass surface too.
Both wet and dry applications are possible. Water based or oil based medium can be used for wet application but if the color will remain between two glass plates, medium should be burnt off before placing the second plate at a lower temperature such as 400-500°C, otherwise the color may be damaged because of the fumes.
Application methods:
1- Spraying
2- Sprinkling
3- Brush application
4- Screen printing
Sprinkling is recommended only for bubbling colors. With the others, when the color is not evenly applied and thickness is too much cracks may appear.
