There are several reasons why a sculpture made with Crayola® may have cracked.

• Forming the Air-Dry Clay around a rigid support or armature is not recommended. The clay gradually constricts as it dries, and the rigid piece remains the same size. This can result in the clay cracking. If you feel an armature is necessary, it is best to choose one that allows a small amount of give, such as crumpled aluminum foil.
• Water can be added to air-dry clay to soften or join pieces. However, too much water may result in cracking as the clay dries. If too much water is added, making the clay very soft, allow the excess water to evaporate before molding pieces.
• Air-Dry Clay pieces should be at least 1/4 inch in thickness. If the item you created is too thin, cracking may occur.

Unused Crayola® Air-Dry Clay can be stored in an airtight container for 3-12 months. Avoid storing clay with added water.

Crayola® Air-Dry Clay can be sealed once your piece is completely dry after 72 hours. Once dry, we suggest using an acrylic varnish. Make sure to test its compatibility with the varnish before applying it to a finished piece.

Sealing your work will not waterproof it. Exposure to water and outdoor elements will have a negative effect on the Air-Dry Clay, so we recommend displaying your sculpture indoors.

Warping occurs when the edges dry more quickly than the inside of the piece. Turning the flat piece(s) periodically; half hour to an hour, will prevent warping. If possible, dry the flat art piece on a rack. The air gets underneath and helps it dry without warping.

Depending on the size of the decorative objects, we recommend using white school glue, Crazy Glue, or Gorilla Glue to adhere objects like stones, beads, glitter, moss, etc., to thoroughly dry Crayola® Air-Dry Clay pieces.

To attach a piece of Air-Dry Clay to wood, an adult should roughly sand the wood where the clay is to be placed. Once the clay has thoroughly dried, use a small amount of white school glue, Crazy Glue, or Gorilla Glue to adhere the Air-Dry Clay to the wood surface.
