Question 3

A satin finish is achieved by brushing or abrading the metal to produce a soft, uniform, non-reflective sheen.

Question 4

What is the correct sequence of abrasive grits when hand-sanding a jewelry piece?

Accepted Answer

Coarse to fine

Answer

Starting with coarse abrasives removes major scratches and imperfections, then progressively finer grits refine the surface before polishing.

Question 5

What is the advantage of using a flex shaft machine for finishing jewelry?
