How to Glue Clay?

Gluing clay depends primarily on the type of clay you are using and whether it is cured (baked) or uncured (raw). This guide focuses on gluing polymer clay based on common techniques and materials.

When working with polymer clay, the best method for joining pieces depends on their state:

Gluing Uncured Polymer Clay

If you need to join two pieces of uncured (raw) polymer clay before baking, using specific bakeable adhesives is recommended. These glues bond with the clay during the baking process, creating a strong connection.

• Recommended Adhesives:
  • Liquid clay: A popular choice that bakes along with the main clay pieces.
  • Other bakeable glues: Products specifically designed for this purpose. The reference highlights:
    • Kato Poly Paste
    • Sculpey Bake and Bond

To bond uncured polymer clay to another piece, it's best to use liquid clay or other bakeable glue such as Kato Poly Paste or Sculpey Bake and Bond. Apply a thin layer between the pieces, position them as desired, and then bake according to the clay manufacturer's instructions.

Gluing Cured Polymer Clay

If you need to join two pieces of cured (baked) polymer clay and the assembled item will not be baked again, a flexible superglue is the most effective option. These glues provide a strong bond without requiring further heat.

• Recommended Adhesives:
  • Flexible Superglue: Look for varieties designed for some degree of flexibility, as polymer clay is not completely rigid. The reference suggests:
    • Loctite Gel Control
    • Zap-a-Gap
    • Gorilla Glue GEL Superglue

To bond two pieces of cured polymer clay that will not be baked again, use a flexible superglue such as Loctite Gel Control, Zap-a-Gap, or Gorilla Glue GEL Superglue. Apply the glue sparingly to one surface, press the pieces together firmly, and hold until the bond sets (refer to the glue product's instructions for specific curing times).

Here is a summary table for clarity:

Choosing the correct type of adhesive based on the clay's state ensures a durable and successful bond for your polymer clay projects.
