How to Paint Glazed Pots
Painting unglazed pots is as simple as applying nearly any type of paint to the rough and slightly porous surface of the pottery, but painting glazed pots presents a bit of a challenge.
The smooth and glossy surface of glazed pottery does not readily accept most paints, and your efforts may begin to flake or rub off soon after painting. The key to painting glazed pots lies in preparing the surface and choosing the appropriate type of paint.
Clean the glazed pot thoroughly with soapy water and a scrub brush to remove all visible dirt.
Combine equal parts water and white vinegar in a small bowl.
Dip a rag into the mixture and wipe the outside of the glazed pot with the damp rag. The vinegar will help remove any greasy residue or fingerprints on the pot which may prevent the paint from adhering properly.
Dry the glazed pot with a clean towel and place it in a warm, sunny spot until it is completely dry.
Paint the clean, dry pot with craft paints designed for use on ceramic or porcelain. These paints will bond with the smooth, glazed surface of the pot while other paints will rub off or begin to chip soon after painting.
Place the painted pot in a dry place and wait for the paint to air-dry.
Place the glazed pot on a baking tray and set it inside your cool oven.
Turn the oven on and set the temperature to 121 degrees C.
Turn the oven off as soon as your oven indicates that it has reached 121 degrees C but do not open the oven door.
Remove the glazed pot from the oven after approximately one hour. The heat will set the paint and make it more durable.
