Cyprus Copper Clay – 50 gram
Cyprus Copper Clay by Cool Tools is a bronze-tavored copper clay designed for jewelry pieces and small sculptures. It requires a two-stage firing process using carbon and typically shows about 20% shrinkage. The material blends copper powder with clay for durable, shop-ready finishes after firing. Suitable for rings, pendants, and decorative beads, this clay balances workability with post-fire brightness.
AUREUS Bright Bronze Clay (100)
AUREUS Bright Bronze Clay (100) from Cool Tools provides a USA-made bronze clay option with a two-stage kiln firing process using carbon. Shrinkage is typically around 10-11%, offering good detail retention for small to medium jewelry pieces. This clay aims to deliver a bright bronze finish suitable for mixed-metal projects and classic bronze-toned designs.
AUREUS Bright Bronze Clay (50)
The 50-gram variant of AUREUS Bright Bronze Clay from Cool Tools mirrors the 100-gram option with a two-stage kiln firing process that uses carbon. Shrinkage sits in the 10-11% range, making it suitable for fine detailing and small components while delivering a consistent bronze look after firing.

Buying Guide
Key factors to consider when selecting bronze or copper-based clay for projects include firing method, shrinkage rate, and surface finish. For kiln-fired clays, two-stage firing with carbon is common and tends to produce more consistent results with finer details. Shrinkage in the 10–11% range helps preserve fine features in small components, while higher shrinkage like 20% is better suited for larger pieces where initial sizing accounts for loss during firing.
- Firing method: Decide between kiln-fired clays (two-stage carbon firing) and air-dry clays. Kiln-fired clays generally deliver stronger, more durable pieces suitable for wearables.
- Shrinkage: Lower shrinkage (10–11%) preserves detail; higher shrinkage (around 20%) requires precise initial sizing for the final dimensions.
- Finish and color: Bronze-tone clays vary in brightness post-fire. For authentic bronze looks, choose clays marketed as bronze or copper bronze with a bright finish.
- USA-made options: Local production can support consistent quality and availability; consider brands that manufacture in the USA for reliability.
- Storage and handling: Some clays come in larger weights suitable for batch projects, while others target small components. Assess your project scope and workspace.
Consider combining bronze clay with other metal clays for mixed-metal jewelry, or use air-dry copper clay for rapid prototyping before committing to a kiln-fired piece. Always follow manufacturer instructions for firing schedules and safety to achieve the best results.
