Painting on Glass Surface: How To Paint Acrylic On Glass

Acrylic paint has the advantage of being able to be used on a variety of textures. Acrylic-style paint has been used for at least two millennia all the way back to the Romans and ancient Egypt. It’s a long way from today’s acrylic paints, because they did use ingredients like manganese and lead to make paint that was then applied to glassware, so it’s interesting to see when it all began. It’s unclear when it became real acrylic paint.

This quick guide will cover everything you need to know about painting on glass with acrylic paint, including processes, paint styles, and just about everything else.

Selecting the Best Acrylic Paint for the Glass Surface

You won’t get the extra bonus of a sturdy background as you can for a white cotton canvas since glass is completely translucent. It’s also beneficial to have bits of white shown out from a painting so you can bring texture and textures of color to your work, but with glass, it’s a whole different story.

You can choose from a variety of acrylics with different properties, but only a limited percentage of them can perform well on glass. Although you can exercise artistic talent and employ some excellent tricks to make the glass (of any color) work in your favor, the paints should also possess a few characteristics in order to successfully cover and adhere to the glass. Any of these characteristics are:


Isn’t it true that if it’s totally coated the glass to the point where you can’t see what it’s painted on, it defeats the purpose of putting it on glass? The more non-transparent there is, the better.

Many painters’ ultimate dream is to make someone look at their finished work and think how did they do that on glass when examining it. To do that try leaving some parts of the glass unfinished as an optical result if you don’t want to use translucent or opaque colors.


The look you want to achieve for the paint finish is crucial. It can make the difference between something that appears to be a hobby and something that appears to be a masterpiece that you use to demonstrate your abilities. But this will depend on entirely your preferences. Just be careful here: if it’s too shiny, it’ll absorb light and detract from the mystique of the painting.

A frosted finish on glass has a really good look about it, but again, it all depends on the kind of art you’re looking for.


True color is about seeing beyond the ads and photoshopped photographs that advertisers use to show off the colors of their acrylic paints. There are two options. For the first time, you could walk into a shop to inquire if you could unscrew an acrylic paint tube and see the exact color. If it suits the name and seems to be what you thought, it’s most likely a decent company to keep an eye out for in the future.

If you don’t have access to any arts and crafts shops in your area, or if you find them to be too pricey (as they normally are), you can purchase excellent acrylic paint online. True color is more difficult to come by online, but you can usually rely on user-submitted photos of the paint out of its tube.


The last thing you want to do is pair labels that don’t go well together. So that you don’t end up with a painting that is terribly non-cohesive, stick with colors that are consistent with each other in texture and finish.

The easiest way to achieve this is to use a brush to gently blend two dime-sized dots of paint together. Keep an eye on how they combine, how they become one colour, and how the finishes connect.

Applying A Tooth Enamel To Your Glass

You might be shocked to find that even the canvas you were working on previously needed a base coat in order for the paint to adhere to it. Gesso is a substance that is added to a canvas to allow the paint to adhere to it. After all, the ink would soak into the cotton canvas under it, so it would warp the final product from how you put it on

The same can be said for glass. We’ll go into various forms of glass later, but for now, keep in mind that acrylic paint does not adhere well to glass and needs a foundation. Glass is almost all smooth (dinnerware, walls, furniture), making it impossible for paint to adhere to it. Your glass’s enamel coating is made to actually hang on to the color, Because it does have a texture that can be characterized as tooth-like. This enamel is available in a variety of colors, enamel-based paints, and, most importantly, enamel-based primers.

These can be applied with a spray or a brush, and they usually take between twenty-four and seventy-two hours to fully stick to the glass of your choice.

When they’re totally dry, you can have a marginally rougher surface to deal with that will really catch and hang onto your paint (hence the term “tooth”). Acrylic paint made for glass may be used, but it’s more suited to arts and crafts on dinnerware or anything similar.

Baking Your Glass

Now you just need the paint to adhere to the glass and stay there. the base layer will assist, but it will not complete the task. To get the color to adhere to the glass properly, you’ll need to bake it. It should be able to handle the heat in this system without cracking, whether it’s a sheet of glass or dinnerware.

Glass does not tend to melt until it reaches temperatures of over 1,400 degrees Fahrenheit, so a 350-degree oven would not break it. It’s just about acclimating the glass to various temperatures.

If you’ve ever read a horror story about a glass pan shattering or burning after being removed from the oven, believe it. Glass bakeware will explode or shatter due to sudden temperature changes, not because the glass isn’t designed to survive certain temperatures.

COE, or coefficient of expansion, is a term you should be familiar with. Under different frequencies and temperatures, different forms of glass extend and contract. The COE will be a long way from the melting point, which means that certain kinds of glass will work and others will crack.

This is what you can do after you’ve decided the kind of glass to use:

  • Preheat the oven while the glass is still fully cold. The glass should be acclimated to the rising temperature. Under no conditions can the oven be preheated.
  • Preheat the oven to 350 degrees Fahrenheit. The heat from the oven is sufficient to cook the acrylic paint onto the glass without burning it or damaging or breaking it.
  • Bake for thirty minutes, no more or no less, and then switching off the oven. Wait another 45 minutes after the oven has been switched off before opening it; you’re gradually lowering the temperature.

And that’s the end of that. The acrylic paint would be perfectly baked onto the tooth enamel at this stage, and it will not come off. If you want to get this off the glass, you’ll have to put in a lot of effort.

Type Of Glass Is Best For Acrylic?

There isn’t a specific type of named glasses where you can look for the right one. Instead, as previously said, you must examine the COE.

Dinnerware glass is particularly good because it’s lightweight enough to allow the COE properties to be a bit more versatile. Thicker glass, such as bakeware, can have a more difficult time expanding, resulting in sudden outbursts. It’s necessary to remember that thinner glass is more vulnerable to temperature changes, so obey the instructions in the previous section to the letter. Then there are glass panes usually 14 inches thick used for windows and remodeling. These are fantastic, but they come with an additional challenge.

You don’t want to cover the whole thing with tooth enamel all four narrow sides and the back, so it would be impossible to contract and stretch. That’s the equivalent to putting a straitjacket on a balloon while trying to fill it with helium; it’s a horrible idea. If you want to finish the rest of the bottle, wait until it’s finished in the oven and has had a chance to cool.

Since the COE rating can drop dramatically, thicker glass would be more difficult to deal with.

Working with bigger pieces of glass for small projects at home and arts and crafts is not recommended. at least if they are going to be heat treated in your conventional oven! Your opportunities would expand if you can build a workshop with a kiln.

What Do I Look Out For While Painting On Glass?

First and foremost, check to see if the glass is in perfect condition: no chips, breaks, or divots. There can be big vulnerabilities that can be abused in the oven during the tempering process, much as you learn of with the windshield and little chips in it.

Take note of how the acrylic color adheres to the bottle. It’s much easier to remove the paint with a few paper towels than it is to wash it with solvent after it’s dried; if it’s not adhering correctly to the primer, clear it off and apply another coat.

Painting on recycled glass is also a bad practice. Recycled glass is made from glass bottles, walls, and debris, as well as everything else the recycling plant sells to manufacturers. To reform it, they’ll apply more soda ash to the clean bottle, but it normally comes out of a lower COE, leaving it much less feasible to rebake. Stronger bottles, such as those used in bakeware, are not made from recycled glass.

Is it possible to use reuse glass?

It’s a daunting task, but it’s not impossible. Once you’ve added the enamel paste, you’ll need to dissolve it correctly with a solvent. This solvent will also melt acrylic paint and the “tooth” layer, restoring the glass to its original state.

One point to bear in mind when reusing a piece of glass is that you must retreat and reheat it once more. Removing the tooth enamel covering, as well as the acrylic color that came with it, is a challenging process.

You could melt down the glass and reform it if you have a home studio with a kiln, but the paint and enamel would blend in and affect everything. You must first clear the glass before melting and reusing it.

Time for some experimenting?

Now that you’ve learned what you need to know about painting using acrylics on glass, it’s time to put it all to the test and show off your skills. You’ll begin to see the world from a modern, more artistic lens, turning any piece of glass into a canvas.

Look for repurposed pieces such as old entertainment cabinets with glass frames, glass coffee tables, and just about everything else you might find. If you’re imaginative enough, you can use anything as a canvas.
