Enamel glass paint
Water-based varnish or spray lacquer
Wash the glass in hot water with dish soap. Dry the glass with towels, then allow to air dry for 24 hours. Wash your hands with soap before painting glass to avoid leaving oily fingerprints on the glass while you paint. The fingerprints make it difficult for the paint to stick to the glass.
Paint the desired design, such as elegat abstracts or floral designs. onto the glass with enamel paints. These paints are designed to stick on glass and are very durable and long-lasting. Use a variety of brush sizes to provide a unique and individual design. Allow the enamel paint to dry for 24 hours. If you wish to apply an additional coat of paint or details with a small paint brush, apply these to the glass. Allow each coat of paint to dry for 24 hours before applying the next coat.
Allow the glass to air dry for 10 days. Enamel paints have a long cure time, but if you let it sit for the appropriate length of time the paint will be very difficult to remove from the glass, even with scraping or scratching, which is what you want for a painted glass surface.
Apply a water-based varnish over the paint with a paint brush. You can also spray the entire surface of the glass with a spray-lacquer, which will seal the paint and improve durability. Allow the varnish to dry for 2 hours, then apply a second coat. Do not touch the varnish with your fingers as it dries to avoid leaving unsightly bumps or fingerprints. Allow the varnish to dry 24 hours before washing or using the glass for anything.
