It may look like silver bubbles, but it's actually #sterling silver casting grain. Casting grain, or #silver shot is used by jewellers, silversmiths and goldsmiths to create one of a kind cast jewelry items. Sterling casting grain is little balls or BB's about 2-5 millimetres in diameter made of 92.5% silver, 5% #copper and 2.5% #zinc. The copper gives it strength and durability while the zinc adds an antioxidant element. 

Casting grain is easy to use, easy to melt, and because it's pre-alloyed, the finished product is of outstanding quality.

Silversmiths pour a measured amount of grain into their furnace, and once melted pour into a mold containing one or several shaped voids, known as casting. Hence, casting grain.
