Assay
An assay is a test that determines the purity and content of precious metals like gold, silver, or platinum in items or materials. Think of it like a quality check that tells traders exactly what percentage of pure metal is in a sample. People working with assays help companies know the true value of metals they're buying or selling. This is similar to how a diamond appraiser determines a gem's value, but for metals. When you see this term in resumes, it usually means the person has experience with testing precious metals or managing the testing process.
