Another great article from Héctor Rubén López .
The articles he writes are informative and his jewelry is amazing.

“How do you alloy silver?
When you buy pure silver its standard of fineness (its “pure” state) is parts per 1000.
When you add pure copper to make the alloy, then that standard will decrease and that’s why you end up with 925 Quality silver, 950 Quality silver or even 900 silver Quality.
Your formula for calculating a silver alloy:
1000 × 75 ÷ 925 = 1.62 “
Visit his website on information on how to alloy silver.

“Raising to a Karat
