Acrylic paint is a popular medium used by artists, crafters, and hobbyists for a variety of projects. Its fast drying time, versatility, and durability make it an ideal choice for many applications.

But can acrylic paint withstand the high temperatures inside an oven? Let’s take a closer look at how acrylic paint reacts to heat and whether it’s safe to use in baked goods or oven-baked craft projects.

How Acrylic Paint Is Made

Acrylic paint is composed of pigment particles suspended in an acrylic polymer emulsion. The acrylic polymer serves as the binding agent that allows the pigment to adhere to surfaces.

In basic acrylic paint, the polymer emulsion is water-based.

Here’s a quick overview of the chemistry:

  • Pigments are Finely ground powders that provide color. Common pigments used include cadmium, iron oxide, carbon black, and titanium white.
  • Acrylic polymer: a thermoplastic resin that is soluble in water when wet but becomes water-resistant as it dries. The most common type used in acrylic paints is polymethyl methacrylate.
  • Additives: Additional ingredients such as thickening agents, preservatives, surfactants, and humectants may be added to enhance the paint’s properties.

How Acrylic Paint Dries

When wet, acrylic paint is soluble in water. As it dries, the polymer particles link together in chains, forming a continuous plastic film. Solvents are absorbed as the paint dries, leaving behind the solid acrylic polymer and pigment.

The drying process of acrylic paint involves:

  • Evaporation: Water and solvents evaporate as the paint dries.
  • Coalescence: Polymer particles fuse together as the paint film forms.
  • Oxidative Cross-Linking: Polymer chains connect via oxidation reactions.

This drying process results in a durable, water-resistant plastic paint film. When fully dry, acrylic paint contains no water; only the solid acrylic polymer and pigments remain.

How Does Heat Affect Acrylic Paint?

Acrylic paint’s durability, flexibility, and resistance to water, UV light, and weathering make it very stable compared to other paint types.

However, heat can alter the physical and chemical properties of acrylic paint.

Physical Changes

  • Softening: When exposed to temperatures above its glass transition temperature (160°F/71°C), acrylic paint will begin to soften. It can become sticky, tacky, or lose form.
  • Melting: If temperatures reach above 320°F (160 °C), the acrylic polymer can start melting and become a viscous liquid.
  • Burning: At very high temperatures above 400°F (204 °C), acrylic paint can scorch, burn, or turn black.

Chemical Changes

  • Oxidation: Heating acrylic paint to high temperatures can accelerate the oxidative breakdown of the polymers. This can cause brittleness or powdering.
  • Off-gassing: Acrylic paint may release fumes, vapors, or smoke when baked at high temperatures. These can contain acrylic monomers, pigment decomposition products, or additives.
  • Color change: Certain pigments may be heat-sensitive and undergo color shifts or fading when subjected to high temperatures.

Is It Safe to Put Acrylic Paint in the Oven?

Based on acrylic paint’s heat sensitivity, it is generally not recommended to place acrylic paint inside a hot oven.

  • Most ovens can reach temperatures between 350 and 550°F. This exceeds acrylic paint’s melting point and glass transition temperature.
  • At baking temperatures, acrylic paint will likely soften, melt, or scorch. This could make a mess and damage the inside of your oven.
  • Heating acrylic paint to normal baking temperatures can cause the off-gassing of potentially harmful fumes.
  • Pigments and additives may decompose when baked, also releasing hazardous gases.

So acrylic paint is not suitable for direct baking or cooking applications. However, there are some exceptions where acrylic paint can be carefully and briefly heated in the oven.

When Is It Safe to Heat Acrylic Paint?

There are a few instances where it may be okay to subject acrylic paint to moderate oven temperatures:


Some crafters and artists will use a technique called “heat-setting” to help acrylic paint fully cure and become more wash- and heat-resistant on fabric.

  • Fabric painted with acrylics can be briefly heated to 320°F or less to set the paint.
  • Temperatures should not exceed 320°F, and heating time should be limited to 1-2 minutes.
  • Heat-setting should be done before washing the fabric using an iron or oven.

Clay and Ceramics

Air-dry polymer clays and polymer clay projects can be baked at temperatures under 275°F. Acrylic paints for polymer clay work are formulated to withstand these temperatures.

  • Specialty acrylic paints for polymer clay release far fewer fumes than standard acrylics.
  • Baking times are very short, usually 5–15 minutes.

Other Materials

Some craft materials, like glass, wood, or metal, may be decorated with acrylic paints and briefly heated to set the paint.

  • Temperatures should stay under 200°F.
  • Exposure time should be just a few minutes.

In these cases, it’s essential to use heat-stable acrylic paints intended for that material and keep heating times very short.

Tips for Baking with Acrylic Paint

While raw acrylic paint isn’t suited for baking applications, there are some ways to work around this and safely use acrylic paints in oven craft projects or baked goods:

  • Seal paint under decoupage medium. Brush on several coats of decoupage medium over painted surfaces to seal and protect the acrylic paint from heat.
  • Use acrylic paint pens. High-heat acrylic paint pens can write directly onto glass, metal, or ceramic bakeware. The paint formulations are more heat-stable.
  • Try acrylic paint powders. Mixing acrylic paint powder into resin lets you create heat-resistant acrylics for jewelry or embellishments.
  • Paint the food, not the pan. Brush acrylic paints directly onto your food or decorate baked clay pieces instead of painting the bakeware.
  • Keep temperatures low. If briefly heating painted pieces, keep oven temperatures below 175°F and cooking times very short.

Acrylic Paint and Food Safety

Using acrylic paint on any surface that will directly contact food is not recommended.

  • Most acrylic paints have not undergone testing for food safety and are not FDA-approved as food-safe.
  • Toxic heavy metals may be present in some pigments. Food-safe options Use earth’s mineral pigments instead.
  • Off-gassing at high temperatures can release harmful fumes and monomers.

There are some acrylic paint options marketed as food-safe,” but these should only be used for decorative purposes, like painting directly onto an edible surface. Reputable food-safe acrylics will be clearly labeled for this use.

For decorating bakeware, dishes, cooking tools, or surfaces that touch food, it’s best to use materials specifically formulated as non-toxic and food-safe.

Frequently Asked Questions

Can you put acrylic-painted objects in the oven?

It’s generally not recommended. Unless the acrylic paint is thoroughly sealed under a heat-resistant coating, exposure to oven temperatures can make the paint run, burn, or release hazardous fumes.

Acrylic paint itself should not be placed directly in a hot oven.

Is acrylic paint heat-resistant?

Acrylic paint has moderate heat resistance up to about 200°F before it may begin softening or losing integrity. It is not resistant to typical baking temperatures above 300°F.

There are specialty acrylic paints formulated for brief exposure to higher temperatures during projects like clay baking.

Can you put acrylic paint on bakeware?

Acrylic paint should not be used directly on bakeware or surfaces that will come into contact with food. The paint may leach chemicals when heated, especially if it begins to bubble, burn, or melt.

Food-safe acrylic paint alternatives specifically made for bakeware do exist.

Is acrylic paint oven-safe?

Standard acrylic paints are not considered oven-safe. They can withstand brief exposure to temperatures below 200°F but will degrade, discolor, or release fumes at normal baking temperatures.

There are specialty high-heat acrylic paints designed for applications like painting ceramic bakeware that have better oven stability.
