Type: Sterling Silver

Description

Made with certified recycled precious metal. Our silver, gold and platinum is refined from certified recycled content rather than newly mined ore, through refiners audited by outside parties. How we source our metal

Professional-grade silver casting grain sold by the troy ounce (20 DWT). Choose from four distinct alloys — Sterling Silver, Fine Silver, Argentium® 940 PRO, and Tarnish-Resistant Sterling — each engineered for jewelry casting with different balances of purity, durability, and tarnish resistance. Whether you require the traditional performance of .925 sterling or the enhanced firescale resistance of modern casting alloys, these grains are formulated to meet the demands of professional jewelers and metalsmiths.

Features

  • Four alloy options to suit a range of casting requirements
  • Sold by the troy ounce (20 DWT) for precise, flexible purchasing
  • Sterling Silver (.925) delivers traditional casting performance
  • Fine Silver (.999) offers maximum purity for high-purity applications
  • Argentium® 940 PRO is designed specifically for modern investment casting with tarnish and firescale resistance
  • Tarnish-Resistant Sterling provides .925 composition with added deoxidizers to reduce tarnishing and firescale

Fabulous customer service.

Silver casting grain is silver casting grain. It's nothing special but they took care of me. Good care. I was in a lurch and they took the worry off my plate. I'm talking Otto Frei up to my students and jewelry making friend.

If you need someone to help you out, Otto Frei is where to go.
