So you want to know if you can bake your acrylic paint in the oven, whether it is on your ceramic project or clay? Well the good news is definitely yes! You can bake acrylic paint in the oven safely and it will give your project the most amazing finish.
A baked finish, results from baking acrylic paint onto a surface at temperatures exceeding 150 degrees Fahrenheit. Baking paint onto clay or ceramic decreases the curing time of the object. This also increases the production rate of painting when dealing with multiple objects, or when dealing with layered coats of differing colors.
By baking your acrylic paint, you can reduce a paint job that would normally take hours to complete, such as if you are layering an object or using multiple colors, to even painting mugs/bowls, which is one of my favorites DIY gift ideas.
I highly recommend this Arteza acrylic paint set, because their colors are very durable and they range from matte to metallic colors! Amazon will often offer discount and deals, so check often!
No special ovens are necessary for baking the paint yourself. Even a toaster oven is suitable for use with parts small enough to fit.
Acrylic paint is also suitable for most ceramic mugs. I recently purchased this ceramic travel tumbler set, and I’ve already finished 4! However, some acrylics are designed specifically for unglazed ceramics. Check the label before purchasing.
After you paint your mug and allow it to dry, use a clear sealant to add shine and prevent the acrylic paint from cracking. I use this Krylon gloss spray from Amazon for most of my projects. I have used it for simple canvas paintings, to glossing my clay bowls that I have baked.
Baking Glazed Ceramics
While a sealant will work for some glazed ceramics, others need to be baked in order to make them dishwasher-safe. After the paint dries, place the mug in a cold oven and set the oven to 350 degrees Fahrenheit. Allow the oven to come to temperature for about 10 minutes, then bake the mug for 30 minutes. Turn off the oven. Do not open the oven until it has cooled completely.
If you use acrylic paint on the outside of your cup or plate, and then spray it with an acrylic clear coat, it will produce a glossy like finish which makes dishes that are pretty to look at, but not safe to place food upon.
You need to use ceramic glaze, like this one, which you can paint on and then cure. It can also be baked at high temperatures, which then makes the pigments fuse and become glass like, and will become permanent.
Did You Know..?
Acrylic paint will stick and adhere to stone and glass, but it can be removed even after thoroughly drying. Usually, ceramic wares are glazed and fired to certain temperatures to keep the ware and the glazes permanently together. Acrylic paint is a fast drying water soluble paint which means that it will peel off if exposed repeatedly to moisture or water.
While you can just air dry, it’s important to remember to use the bake method for items you intend to wash in the dishwasher, or even eat off of.
The Bake Method
- Allow the painted item to dry for 24 hours to be sure all layers of paint have dried.
- Place project in a cool oven, as the glass/ceramic must heat gradually with the oven to avoid breakage; do not place glass in a hot oven.
- Set the oven temperature to 350ºF.
- Once the temperature has reached 350ºF, allow the project to bake for 30 minutes.
- After 30 minutes, turn the oven off and let glass or ceramic cool down completely before removing from the oven.
- Do not use for 72 hours.
How to Seal Acrylic Paint on Glass
You can use the same baking method for your glass project, but make sure to follow the heat up and cool down rules to the T, because if not the glass will break/crack. After it’s cured, the best thing for acrylic paint on glass is an acrylic medium or varnish.
A good quality varnish, (matte or gloss depending on your preference), is relatively thick and can be thinned with water, but do not dilute it too much since it should not be runny. Brush it on with a soft nylon brush, then leave it alone until it is fully dry.
You will also need to prime the glass with “stix” primer. That will give a surface your acrylic paint will bond to. Wait around 8-12 hours, then clear coat it with sealant. If the glass is 40 square inches an under, I would spray paint the lacquer sealant. You will want to do three coats. Wait until the first coat dries, then spray coat number two, and so on.
If the glass is 41 square inches or larger then you want to brush on the lacquer. Again, you are going to brush on 3 coats, waiting for it to dry between coats. Now you can sit back and enjoy your work. This method will help your acrylic paint stick to the glass much better.
Can You Bake Acrylic Painted Glass in the Oven?
Yes, you most definitely can. Just make sure you follow the steps above to properly paint and then seal your paint. Before putting in the oven, also make to follow the steps for the warm up/cool down to ensure your glass doesn’t crack or break.
I usually paint mason jars, and it is one of my favorite glass items to put in the oven. Besides Pyrex, you can certainly put mason jars in the oven. I know many people that bake desserts in them with no problems. Like any glass, it is susceptible to thermal shock so don’t take it from one extreme temperature to another too drastically.
Also, when you take the glass out of the oven, make sure the surface you place it on is completely dry. Even a few drops of water can lead to shattering.
I have been seeing a lot of “paint night” groups and invites, but while they traditionally include painting on a canvas and then taking it home, lately I have been noticing that they now paint on glass, for example a wine glass or even plates.
Once you paint your glassware, they instruct you to take it home and “finish” your piece by baking it in the oven.
Using acrylic paint on glass is a simple and fun art form, as long as you have the right supplies and follow some fairly easy instructions on how to complete your project. Other than a wine glass, there are many other types of glass that acrylic paint can be used to decorate.
Some examples of other various glassware to paint on can be vases, various bottles (think mason jars!), mugs, bowls, cake stands, planters, pictures, windows, mirrors, and faux stained glass.
Imagine the possibilities to create a personalized gift for someone special! It is extremely important to remember to only paint the outside of any glassware items that you will be using to eat or drink out of.
You do not want anyone ingesting your painted piece, especially if it is a gift. Non-toxic paint is marketed for its non-toxic effects on breathing, but no paint should ever be ingested.
