Fire skills

Annealing silver explained — why heat makes metal workable

The torch — silver's reset button and the bench's first rite of passage.

Hammer and bend silver and it stiffens, stiffens, then cracks. Annealing
is the reset: heat to a dull cherry red, and the metal forgets its stress.

What is happening

Hammering distorts the crystal structure (work-hardening). Annealing lets
crystals re-form — softness returns, shaping continues. Hardening returns
with more work — which is also how you MAKE stiffness on purpose (hammer
hardening a finished edge).

Reading the colour

A dim room helps: dull cherry red across the whole piece = done. Overheat
and silver gets crusty (fire scale, pits). Pickle (the acid bath) cleans
fire stain afterwards — the studio does this for you.

Quench or air?

Silver: quench is fine (brass is the fussy one). Then it goes in pickle hot
— tongs, not fingers.

Where you learn fire

Torch confidence is instructor-supervised by design — the
Foundation Metalwork course
is where most students first hold a flame on silver. Next on the ladder:
soldering first joints.
