Oven bake clay

Types of oven bake clay

Oven bake clay is a versatile medium used in crafting, sculpting, and jewelry-making. Several types of oven-bake clay are available, each with unique characteristics and benefits, making them suitable for different artistic applications. Here are some of the primary types:

• Polymer Clay

  This is the most popular type of oven-baked clay among crafters and artists. It is composed of polyvinyl chloride (PVC) and various plasticizers, pigments, and other additives. This type of clay is available in various colors and can be blended to form custom shades. Additionally, it is highly flexible before baking, allowing for intricate detailing, shaping, and smoothing. Ideally, it is used for jewelry, figurines, beads, and other delicate crafts. After shaping, the clay is baked in a standard oven at a specific temperature (usually between 265°F and 275°F or 130°C to 135°C) to cure and harden. The resulting finish is durable and retains fine details. Moreover, it is non-toxic when cured. However, it should be kept out of reach of small children, as it can be swallowed before baking. It also requires a dedicated workspace as it can be slightly dusty when manipulated.

• Fimo Clay

  Fimo clay is a type of polymer clay manufactured by Staedtler. It is similar to polymer clay but is available in a broader range of colors and effects, including metallics, translucents, and glitters. In addition, it has a firm texture that makes it ideal for intricate details and fine work. Also, it is popular in jewelry-making, miniatures, and complex sculptures. Fimo clay is baked at temperatures similar to those used for polymer clay. Its durability and detail retention after curing are similar to those of polymer clay.

• Apoxy Clay

  Apoxy clay is a two-part epoxy sculpting clay that comes in a soft, moldable consistency and hardens when mixed. It has a long working time before curing starts, allowing for extended sculpting sessions. It is ideal for creating sculptures, repairs, and models requiring high strength and durability. Also, it is used in applications where a strong bond is needed, such as plumbing and electrical work. The clay is air-dried at room temperature to cure. Its finish is hard and strong, with a surface that can be sanded or painted. Additionally, it is non-toxic when cured, with a low odor during mixing. However, it requires precise mixing of the two components for proper curing.

• Paper Mache Clay

  This oven-baked clay is a paper-based, lightweight, and easy-to-use medium. It is made from recycled paper, flour, water, and other additives. This clay is eco-friendly and non-toxic. It can be shaped into various forms and is ideal for crafts, children's projects, and artistic creations. Typically, it has a soft and malleable texture, making it easy to work with. It is used for decorative items, sculptures, and school projects. This allows for easy application of paint and finishes. Paper mache clay dries to a hard surface when air-dried or baked. Although it has a long drying time when air-dried, its finish is strong and lightweight. This type of clay is easy to clean and non-toxic, making it ideal for use by children. However, it is less water-resistant than other clays and should be kept away from moisture.

How to choose oven bake clay

• Purpose

  Determine the clay's intended use: for instance, if it's for making beads, models, or sculptures. For craft items that don't need to be strong, like decorations, low-strength clay like earthenware is better. If the items require more strength, such as jewelry or functional pieces, use high-strength clays like stoneware or porcelain.

• Compatibility

  Ensure that the clay works well with the intended use, particularly with any other materials that will be applied. This is important for items like models or prototypes that will be cast or molded. To avoid issues with adhesion or melting, check that the clay is compatible with the materials, including resins, adhesives, and other modeling compounds.

• Color and Finish

  Consider the clay's color and finish, as these will affect the final look of the piece. Choose a color that matches the intended use, whether it be a natural earth tone or a bright, synthetic hue. To get the desired surface characteristics, consider if the clay needs to be smooth and fine or coarse and textured. These finish choices range from matte to glossy and may require specific treatments or firing temperatures.

• Workability

  Evaluate the clay's workability in terms of texture, consistency, and drying time. For detailed work or small pieces, a clay with a fine texture and smooth consistency is easier to manipulate. Consider the drying time for air-dry clays to ensure sufficient working time for complex projects.

• Durability and Strength

  Consider the clay's durability and strength for functional or long-lasting pieces. Stoneware clay is denser and more robust after firing, making it suitable for functional pottery. For pieces requiring high strength, such as sculptures or architectural elements, use high-strength clays like porcelain or stoneware.

• Safety

  Consider the safety of the clay, especially for projects involving children or sensitive applications. Ensure the clay is nontoxic and free of harmful chemicals like phthalates, heavy metals, and VOCs. For items that will be used for food, ensure the clay is food-safe and has been fired to the appropriate temperatures.
