Soldering
Argentium solders have been developed to give a good colour match with Argentium silver - (Argentium
solders are available from Rio Grande - riogrande.com).
Do's
•
Always make sure that surfaces are clean and degreased before soldering.
•
Remember that Argentium silver glows a paler colour than traditional sterling silver at soldering
temperatures - it is recommended that soldering applications should be carried out in a shaded area
to avoid overheating.
•
To minimise distortion of Argentium 960-Pure during soldering operations, it is recommended to
carry out a pre-annealing step - simply heat the sheet to a pale-red annealing temperature and allow
to air-cool to room temperature.
•
Argentium silver can be brittle at red-hot temperatures - make sure that the silver is well supported
during soldering applications and simply wait a few seconds for the red glow to disappear before
touching or moving.
Don'ts
•
Don't quench soldered pieces as this can cause the solder joint to fracture.
•
Be careful not to touch or move your Argentium silver piece too quickly after soldering as this can
cause brittleness - wait until the red glow has completely disappeared.
Flux
Argentium 960-Pure is highly resistant to firestain, it is therefore only necessary to flux the seam to be
soldered rather than applying flux to the whole piece. The following fluxes are recommended (use as
directed by the manufacturer):
•
My-T-Flux (supplied by Rio Grande, USA)
•
Battern's Flux
•
Prip's Flux
N.B. 'Handy' or 'Easy Flow' type fluxes can cause staining with Argentium silver.
Fusing
Unlike traditional sterling silver, Argentium 960-Pure can be easily fused - producing strong, clean joints
with the added benefit of not having to remove excess solder or having visible solder seams on finished
articles. Instruction DVDs by Ronda Coryell are available to purchase - please visit rondacoryell.com or
riogrande.com for further information.
Argentium 960-Pure will fuse with: Argentium silver, pure silver, gold and platinum.
Do's
•
Thoroughly clean/degrease sections being fused.
•
It is recommended to apply a diluted flux to the sections being fused.
•
Heat the piece with a gas/air flame and work in a shaded area (this makes it easier to visualise the
temperature by the colour/glow of the metal).
•
Argentium silver will glow brighter as the temperature rises - look for a 'wet' surface appearance as
an indication of the correct fusing temperature.
•
Allow the red glow to disappear before touching or moving the fused piece.
Don'ts
•
Be careful not to touch or move your Argentium piece too quickly after fusing as this can cause
brittleness - wait until the red glow has disappeared.
