PRESENTATION OUTLINE
WHAT IS IT?
- It is a mixture of 92.5% silver and 7.5% other metals(typically copper)
- Fine Silver(99.9%) is too soft but contains a pretty color.
- Due to silver's softness, it is often added to other metals to give it strength.
- It is commonly paired with copper to give it strength while preserving its ductility.
Although Copper is commonly paired with Silver, it easily tarnishes.
Other metals can replace copper in order to reduce porosity, eliminating fire scale, and increase resistance to tarnish, such as Germanium, Zinc, Platinum, Silicon, and Boron.

WHY IS IT USEFUL?
With the addition of a metal, the lustrous silver gains the hardness/strength of other metals-making it popular for jewelry, fine dining, and coins. All of which target the shiny appearance of the silver.

EARLIEST USE?
- found in Continental Europe around the 12th century
- Commonly used as currency instead of jewelry at the time.
-The sterling alloy originated in continental Europe.
-The sterling alloy was being used for commerce in the area that is now northern Germany.
-In England the composition of sterling silver was subjected to official assay before 1158, but it's purity was probably regulated from centuries earlier, in Saxon times.

FUN FACTS:
-Silver has been coined to use as money since 700 BC.
-The term 'sterling silver' in reference to the grade .925 silver emerged in England in the 13th century.
-In ancient Egypt and Medieval Europe, silver was often more valuable than gold.
Others:
-Silver is harder than gold, but softer than copper.
-Coin silver melts at a slightly lower temperature than sterling because it has more copper alloy in it; usually any where for 10 to 20 percent of it is an alloy.
