Class on Electroforming in Jewelry

Introduction to Electroforming

• Presentation by Katia Plesco, jeweler, and teacher.
• Electroforming: an electrochemical process to coat objects with metal.
• Necessary equipment: tank (can be small), acid solution, copper plates, and power supply.

Electroforming Process

• Object to be electroformed is immersed in the acid solution.
• Electrical circuit: copper plate (positive charge) and object (negative charge).
• Copper microparticles deposit on the object, forming a metallic layer.
• Comparison with electroplating: thicker layer in electroforming.

Preparation of Objects

• Objects need a copper wire and coating with conductive paint.
• Conductive paint: not commercially available, own adapted recipe.

Safety and Equipment

• Diluted acid solution; safe handling.
• Low-voltage equipment; minimal risk of electric shock.
• Keep out of reach of children and pets.

Materials for Electroforming

• Organic materials: leaves, flowers, seeds, papers, fabrics, shells.
• Synthetic materials: plastics, resins, waxes.
• Waterproofing: necessary for organic materials.

Examples and Applications

• Electroformed jewelry and objects: examples of leaves, seeds, fabrics, and compositions.
• Ability to create large and lightweight pieces.
• Application in jewelry such as chokers, pendants, earrings.
• Integration with other techniques (e.g., stone setting).

Partial Electroforming

• Possibility to electroform only part of the object.
• Combination with other materials, keeping the original material visible.

Additional Techniques

• Electroforming can be used for molds and casting.
• Engraving on plates: addition/exclusion of metal in specific areas.

Examples from Other Authors

• Diversity of styles and techniques in electroforming.
• Combinations with ceramics, pearls, and textures.

Electroforming Course

• Online course with recorded classes and access for one year.
• Includes support and guidance, list of suppliers, PDF manual.
• Teaching tank and solution maintenance, object compositions, relief engraving.

Conclusion

• Electroforming as a versatile and accessible technique for creating jewelry and objects.
• Invitation to participate in the course and explore the creative possibilities of electroforming.
