  1. Select the type of paint

    Art at Home Studio suggests using one of these three types of paints for painting glass: acrylic enamel paints, regular acrylic paints mixed with glass and tile medium or specialized solvent-based glass paints.

  2. Paint and dry

    Paint the glass and let it dry thoroughly, for at least 24 hours.

  3. Cure the paint

    The next step varies by which type of paint was used. For acrylic enamel paints, the paint just needs to be left to cure for approximately two weeks with no further sealing necessary. For other types of acrylic paints, the final product needs to be heat-sealed.

  4. Bake the glass

    If your glass needs to be heat-sealed, place the glass item into a cold oven and set it to 330 degrees Fahrenheit. When the oven reaches the correct temperature, begin timing. Bake for 30 to 45 minutes and then turn the oven off and let it cool down completely. Avoid inhaling the paint fumes during this process.

  5. Improvise

    If the glass item is too large to fit into an oven, Art at Home Studio suggests using a hair-dryer set on low heat to cure the paint.
