To make painted wine glasses, you must first clean them thoroughly, then use glass paint to paint designs onto the outside. You can paint freehand, or use stencils by taping designs to the inside of the wine glasses. After painting, the glasses need to be cured, ensuring the paint stays on permanently, by baking them briefly in the oven. Curing the wine glasses also ensures that they are dishwasher safe.
- Clean the wine glasses thoroughly
Wash the wine glasses in warm, soapy water, and rinse with warm water. Dip a paper towel in rubbing alcohol or white vinegar, and wipe the glasses in and out. Turn them upside down on a kitchen towel, and let the wine glasses air dry completely.
- Gather painting supplies
Use glass paints of any color, which you can purchase at any craft store. Glass paints generally come in both transparent and opaque varieties. Choose paint brushes of various sizes, depending on what you want to paint. Gather any patterns needed if you plan to follow a specific design.
- Paint your wine glass
Paint your wine glass however you like, but leave about 3/4-inch of space around the rim clear of any paint. Paint should never come into contact with the area used for sipping. If you wish to follow a specific pattern you have drawn out, tape it to the inside of the wine glass, and follow the pattern with paint on the outside.
- Cure the painted wine glasses
Allow the wine glasses to air-dry for an hour, then place them upright inside a cool oven. Set the temperature to 350 degrees Fahrenheit, and leave the glasses to bake for 30 minutes. Turn the oven off after 30 minutes, and leave the glasses in the oven until they are completely cooled. Wait another 72 hours before using the wine glasses. If you prefer not to cure the wine glasses, let them air-dry for 21 days before using.
