Why Gold Assaying Matters

Assurance of Authenticity

Assays protect against fraud by confirming whether gold is real.

Determining Purity and Value

The higher the purity, the more valuable the gold — assays provide exact percentages.

Protecting Buyers and Sellers

Assay certificates build trust in gold transactions worldwide.

Historical Background of Gold Assaying

Ancient Fire Assay Methods

Dating back to over 2,000 years, the fire assay is one of the oldest scientific techniques.

Gold Assaying in the Middle Ages

Medieval guilds relied on touchstones and fire assay to protect trade integrity.

Evolution into Modern Practices

Today, digital tools and XRF technology make assaying faster and more accessible.

Main Methods of Gold Assaying

Fire Assay (Cupellation)

The most accurate but destructive method, widely used in official gold refining.

Touchstone Method

A simple method using acids, though less precise than modern techniques.

X-Ray Fluorescence (XRF)

A quick, non-destructive method, widely used by dealers and jewelers.

Inductively Coupled Plasma Mass Spectrometry (ICP-MS)

A highly advanced method for trace element analysis.

Fire Assay: The Gold Standard

Despite technological advances, fire assay remains the benchmark.

1. Weighing the Sample – A small piece of gold is cut and weighed.

2. Mixing with Fluxes – The sample is mixed with lead and other chemicals.

3. Cupellation in the Furnace – Impurities are absorbed, leaving pure gold.

4. Weighing the Pure Gold – The remaining bead of gold is carefully weighed to determine purity.
