Use oil paint on glass to get a stained glass effect.
Painting glass typically requires a type of paint that you bake in a kiln, but if you use oil paints, you can avoid using one. Mix oil paints to achieve the exact color that you want to use with the glass. Before doing this, prepare the glass to ensure the paint will stay in the position that you place it and will not run or smear.
Instructions
1. Sandblast the glass before you begin to paint. Move up and down slowly on the glass until you have covered the entire surface. If you are sandblasting an item like a glass or a bowl, cover the entire surface you plan to paint. If you are sandblasting a sheet of glass, only sandblast the side you intend to paint.
2. Sand the surface with the wet/dry sandpaper to continue to roughen it. If the glass is too smooth, the paint will not stick or will begin to run while it is drying. Use a brush to apply a little bit of paint to a small area to see how the paint reacts, and use the sandblaster or sandpaper again if necessary.
3. Fill the airbrush with the paint and apply it to the glass to create the image or pattern that you want. Move slowly to allow the paint to settle onto the glass before moving on. Using an airbrush will apply the paint in a more uniform manner and prevent it from dripping or sliding.
4. Brush with the paint to add details. Place the glass or the item on a flat surface overnight to allow the paint to dry. Do not place the glass in a kiln as you would if you were creating stained glass, as this will cause the oil paint to begin to chip or crack.
