Clay can be used as a paint additive to achieve a thicker texture. Clay paint is made by mixing clay, sand, and wheat paste. The type of clay and sand used can vary depending on the desired texture. For a smooth finish, the clay and sand should be fine, with small particle sizes. When painting on polymer clay, acrylic paints are the most commonly used, and mixing paint into uncured clay can add colour and texture. However, water-based paints can create bubbles in the clay when baked, so heavy-body acrylic paint is recommended for a thicker consistency.

Clay paint recipes often include clay, sand, and wheat paste
Clay paint is a simple mixture of clay, sand, and wheat paste. You can buy bagged powdered clay or dig up your own clay from your backyard. If you're using local clay, you must first screen it to remove stones and other particles by pressing the clay through a fine screen. The clay and sand should be quite fine, with small particle sizes.
To make wheat paste, bring 4 cups of water to a boil. While the water is heating up, add 1 cup of white flour to 2 cups of cold water and stir well to remove any chunks. Once the water has boiled, add the water and flour mixture, stirring continuously over low to medium heat until the mixture thickens. Be careful not to burn the bottom. The final texture should be smooth and thick, resembling peanut butter.
Mix the clay, sand, and wheat paste together, adding water if necessary. The final clay paint texture should be smooth and slightly stiffer than commercial paint. You can experiment with adding small amounts of pigment to achieve your desired colour, but be aware that the colour of the pigment will be influenced by the type of clay used. For example, white clay like Kaolin will result in brighter colours than brown clays.
If you're using sand from your local environment, you can process it similarly to the clay by screening it through a fine mesh to remove any large particles. You can also purchase very fine sand from a pottery supply store or use inexpensive "play sand" from a home centre.
Clay paint can be applied to a variety of surfaces, including wood and interior drywall, using a wide paintbrush. It is recommended to apply at least two coats and wait for the paint to dry between coats.

Water-based paint mixed with polymer clay can create bubbles, altering texture
Water-based paint can be mixed with polymer clay to create a thicker texture, but it can also cause bubbles to form in the clay as it bakes. This is because the water in the paint will turn to steam, and some crafters may desire this effect, especially when replicating materials like stone.
If you want to avoid bubbles, a small amount of heavy-body acrylic paint can be mixed into the clay instead. Acrylic paint is commonly used on polymer clay, as it is affordable, opaque, and easy to work with, coming in a wide variety of colours. However, cheaper brands of acrylic paint may be too watered down to provide full coverage, so a decent-quality "craft" acrylic paint or "artist-quality" paint may be preferable.
If you are painting onto the surface of polymer clay, rather than mixing the paint into the clay itself, it is important to let the clay cool after baking, to ensure the paint adheres correctly. If the paint is still not adhering, lightly sanding the surface with high-grit sandpaper can help to create a rougher texture for the paint to grip onto.
Alternatively, clay paint can be made from scratch using bagged powdered clay or dug-up clay, mixed with water and wheat paste. This paint can be used on a variety of surfaces, including wood and drywall, and can be applied over existing paint. The final texture should be smooth and thick, with a consistency similar to peanut butter.

Sanding clay can help paint adhere, but can also create unwanted texture
When working with clay, it is important to consider the type of paint being used, as well as the application process. While sanding clay can help paint adhere better by providing a rougher surface for the paint to grip onto, it can also create unwanted texture if not done properly.
If you are working with polymer clay, you may encounter issues with paint adhesion if the clay is not properly cooled after baking. In such cases, lightly sanding the surface with high-grit sandpaper can help improve paint adhesion. However, it is important to work carefully and avoid altering any intricate details on the clay surface. Additionally, ensure that you wipe off any clay dust before painting, as this can mix with the paint and create an unwanted texture.
For those who want to add colour directly to the clay, mixing a small amount of heavy-body acrylic paint into uncured polymer clay is an option. This method allows you to create a custom colour and avoid the challenge of painting the clay's surface. However, it is important to note that mixing water-based paint into polymer clay can produce varying results. The water in the paint can turn into steam during the baking process, creating bubbles in the clay and altering its texture.
When working with other types of clay, such as natural clay, you can create your own non-toxic paint by mixing clay, sand, and wheat paste. The addition of sand provides a textural element to the paint, but it is important to use fine sand to avoid a coarse finish. Alternatively, you can create a faux clay look on glass vases using acrylic paint and baking soda. The baking soda gives the paint a "fluffy" appearance while dry, resulting in a clay-like texture.
In summary, sanding clay can be beneficial for improving paint adhesion, but it requires a gentle and careful approach to avoid unwanted texture. Additionally, the choice of paint and application technique plays a significant role in achieving the desired results. Whether you are painting the surface or mixing paint directly into the clay, always test your methods on a small area first to ensure the desired outcome.

Acrylic paint is commonly used on polymer clay, but quality varies
Acrylic paint is the most commonly used paint on top of polymer clay, especially when creating an antique finish on dimensional/textured surfaces. Acrylic paint is popular because it is affordable, opaque, and easy to work with. It comes in a wide range of colours and can be found easily.
However, acrylic paint comes in different qualities. Less expensive brands of acrylic paint tend to be more watered down, so they won't cover as opaquely with each coat. Artists are therefore advised to use at least a decent-quality "craft" acrylic paint or "artist-quality" acrylic paint.
To create an antique finish on beads, jewellery, or other clay items, artists can dilute acrylic paint with water or start with a thin paint. The watered-down paint is then brushed onto the creation, and wiped off the raised areas before it dries. This process works well on stamped or carved designs in the clay, as the watered-down paint will lay in the crevices and enhance the detail.
Artists can also try mixing paint into uncured clay to add colour. Mixing water-based paint into polymer clay can have varying results. As the clay bakes, the water in the paint will turn to steam, creating bubbles in the clay. Some crafters are after this texture, especially when replicating materials like stone. However, if a smooth finish is desired, artists can mix a small amount of heavy-body acrylic paint into the clay instead.
It is important to note that paint colours can fade over time, due to handling or exposure to air or sun. Using a quality paint can help creations last longer. Artists should look for paints with pigments instead of dyes and consider heavy-duty options for long-lasting clay crafts.

Clay can be mixed with wax paste, fibre, or wheat paste to make it less brittle
Clay paint is made from clay, sand, and wheat paste. It can be used on a variety of surfaces, including drywall, wood, and even already-painted drywall. Clay can also be mixed with additives such as sand to create a thicker texture.
Clay can be mixed with other substances to make it less brittle. For instance, mixing clay with fibre gives it new properties. Fibres such as nylon are slightly absorbent, which allows water to move through the mix. This is in contrast to cellulose fibres, which are less desirable because they absorb water and swell when wet, leaving voids in the clay that can cause cracking.
Clay can also be mixed with wax paste to make it less brittle. One can make modelling clay at home by mixing calcium carbonate, wax, petroleum, and mineral oil. If the clay is too firm, one can add more oil and limestone powder to make it stickier. If the clay is too crumbly, one can increase the amount of wax and oils to soften the texture.
Clay can also be mixed with wheat paste to make it less brittle. Wheat paste is made by boiling four cups of water and adding a mixture of one cup of white flour and two cups of cold water. This mixture is stirred over low to medium heat until it thickens. The final texture should be smooth and thick, almost like peanut butter.
