CH 4 Jewelry study guide

These flashcards cover key concepts and techniques related to metalworking, including hammering, annealing, stamping, chasing, engraving, Keum-Boo, and granulation.

What is the appeal of hammer marks on metal?

They celebrate the transformation from raw material to a crafted object and carry the gesture of the craftsman.

What does the term "Martelé" refer to in metalworking?

It refers to a line of hollowware introduced by Gorham Silver, influenced by the Arts and Crafts Style, emphasizing hand hammering.

How can hammer marks be used to hide fingerprints?

Hammer marks create a rough texture that can disguise unsightly fingerprints on metal objects such as handles and flatware.

What is the purpose of annealing metal before roll printing?

Annealing softens the metal, making it more pliable for embossing textures.

What factors affect the clarity of stamped designs?

Tool design, metal thickness, hammer force, and the surface the workpiece is resting on.

What differentiates chasing from engraving?

Chasing incises lines into metal without removing material, while engraving involves cutting into the surface.

Why is it essential to secure the workpiece during engraving?

A secure grip allows for controlled movements and precision in making cuts.

What is the recommended angle for sharpening most gravers?

The face angle is typically 45°, less for soft metals and more for hard ones.

What is the process of Keum-Boo in metalworking?

It is a technique where pure gold is joined to other metals using moderate heat and pressure.

How can you achieve a successful bond during granulation?

Introduce another metal to create a low-melting alloy at the point of contact for bonding.
