Painting on glass is a fun and creative way to add colour and design to your glassware, but it's important to use the right type of paint and curing method to ensure your artwork lasts. There are several types of paints and methods available for painting on glass, including air-drying and baking methods. The curing method you choose will depend on the type of paint used, so it's important to carefully read the instructions on the paint container. Baking painted glassware is a popular method as it expedites permanence and creates a more durable surface. Glassware paint can be baked in the oven to set the paint permanently, but it's important to follow the correct procedure to avoid breakage.

What You'll Learn
Preparing the glass surface
Cleaning the Glass Surface
Start by thoroughly washing the glass surface with warm soapy water to remove any dirt, dust, or grease. Rinse the glass with warm water and allow it to dry completely. This step ensures that there is no residue on the glass that might interfere with the paint's adhesion.
Removing Residue
After washing, use a paper towel dampened with rubbing alcohol or white vinegar to wipe down the glass surface. This step ensures that any remaining soap film or oils from fingers are removed. These substances can repel paint, so it is important to eliminate them. Set the glass aside for about 15 minutes to air dry.
Using Stencils (Optional)
If you plan to paint only a specific area of the glass and not the entire surface, you may want to use stencil tape to tape off the desired shape or area. Alternatively, you can use adhesive stencils or stencils cut with a Cricut machine to create more intricate designs.
Drying the Glass Surface
Before applying paint, ensure that the glass surface is completely dry. This step is crucial because any moisture on the glass can affect the paint application and curing process.
Curing the Paint
Once you have prepared the glass surface, you can begin painting. After painting, allow the item to dry for at least one hour to ensure all layers of paint have dried completely. The curing process, which involves baking the painted glass, is essential to seal the paint and make it durable.
Please note that specific curing instructions may vary depending on the type and brand of paint used. Always refer to the manufacturer's instructions on the paint container for curing directions specific to your chosen paint.

Curing methods
When it comes to curing painted glass, there are two main methods: baking and air-drying. The curing method depends on the type of paint used, and the manufacturer's instructions should always be followed.
Baking Method
The baking method is suitable for glass-specific paint and involves placing the painted glass in an oven. It is important to ensure that the painted item is completely dry before baking, which typically takes about an hour. The oven should be preheated to 350ºF, and the glass should be placed inside only when the oven is cool to avoid breakage due to rapid temperature changes. Once the oven reaches the desired temperature, the glass should be baked for 30 minutes. After baking, the oven should be turned off, and the glass must be allowed to cool completely inside the oven. The glassware should not be used for at least 72 hours after curing. This method is recommended for items that require regular washing, as it seals the paint better. It is also suitable for glassware that will be washed in the top rack of a dishwasher, as the air-dried method may not be safe for this purpose.
Air-Drying Method
The air-drying method is a longer process, taking about 21 days for the paint to fully cure. During this time, the painted glass should be allowed to air dry, and it will be ready to endure outdoor elements after curing. This method is recommended for items that are infrequently handled and not regularly washed, as the paint may chip over time. It is also suggested for items with a glitter finish.
Additional Considerations
It is important to note that non-tempered glass may not withstand temperatures above 250ºF (120ºC). Therefore, it is crucial to ensure that the glassware can withstand the baking temperature and time. Additionally, some paints, such as DecoArt Crystal Gloss Enamels Glitter Paints, do not require heat setting.

Bake method instructions
When using the bake method to cure paint on glass, it is important to follow the instructions carefully and to use the correct type of paint. The bake method is only suitable for glass-specific paint that is meant to be cured in an oven. FolkArt Enamels, FolkArt Multi-Surface Acrylic Craft Paints, and Pebeo paints are examples of brands that offer paint that can be cured in an oven.
Before baking, ensure that your painted item is completely dry. It is recommended to allow the paint to dry for at least one hour, or until it is dry to the touch. During this time, preheat your oven to 350°F (170°C or 250°F, according to some sources). It is important to place your painted item in the oven before it starts to heat up to avoid breakage due to rapid temperature changes.
Once the oven has reached the desired temperature, start timing and bake your painted item for 30 minutes. After 30 minutes, turn off the oven and allow the glass to cool completely inside the oven. Do not use the item for at least 72 hours after baking.
If you are painting glassware that will come into contact with food or drinks, such as plates or glasses, it is recommended to use the oven bake method instead of a spray or brush-on sealant. This will ensure that the paint is cured onto the glass and is safe for use.
Additionally, if you plan to add glitter to your project, it is recommended to bake the glass first and then apply the glitter after baking, as most glitters are made of plastic and will melt in the heat.
For extra durability, you can consider adding a clear coat or lacquer coating after the initial baking process and then baking the glass a second time. However, always refer to the manufacturer's instructions on the paint container for specific curing information, as curing methods can vary depending on the paint brand and type.

Air-dry method instructions
To paint on glass, you can use a variety of paints, including acrylic paint, glass paint, and spray paint. Glass paint is specifically formulated for glass and is available in craft stores. It is important to clean the glass surface thoroughly before painting to ensure the paint adheres properly. This can be done by washing the glass with warm soapy water, rinsing it with warm water, and then wiping it down with rubbing alcohol or white vinegar. The glass should then be set aside to air dry for about 15 minutes.
Once the glass surface is prepared, you can start painting. If you are using a paint that requires curing, there are two methods you can use: the bake method and the air-dry method. The air-dry method is a good option for outdoor decor as it allows the paint to endure the elements. Here are the step-by-step instructions for the air-dry method:
- Allow the paint to dry for at least one hour after painting to ensure that all layers of paint have dried.
- Let the painted glass item air dry for at least 20 to 21 days. The longer drying time ensures that the paint is permanent and durable.
- During the curing process, avoid washing the painted glass with an abrasive sponge or placing it in the dishwasher, as this can damage the paint.
- After the paint has cured, the glass item can be gently hand washed or placed in the top rack of a standard, non-commercial dishwasher, as long as it does not have pot-scrubbing features or top jets.
- Painted glass items are not microwave-safe, so avoid using them in the microwave.
By following these instructions, you can successfully cure your painted glass items using the air-dry method, resulting in a durable and long-lasting finish.
