Crucible in 2000 Degree Furnace Methodology involves mixing ground ore with dry chemicals (flux) & fusing in hot furnace.	Molton Flux & ore are mixed together & put into a crucible. The crucible is placed in a hot furnace to initiate melting of ingredients.
Fire Assay Molton The flux is designed to draw out the impurities within the ore into the molten glassy slag, collecting the precious metals into lead & silver.	Glass-Lead Button During the fusion, chemical & thermodynamic reactions occur, resulting in a glassy slag & a lead-silver button.
Cupels Entering Furnace Lead button is then placed in the cupellation furnace	Cupellation Furnace The lead button contains the precious metals, silver and gold from the ore.
Cupellation Cupels exiting the furnace.	Gold Bead End result is the production of physical precious metal bead

Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), is an analytical technique used for the detection of chemical elements. It is a type of emission spectroscopy that uses the inductively coupled plasma to produce excited atoms and ions that emit electromagnetic radiation at wavelengths characteristic of a particular element. It is a flame technique with a flame temperature in a range from 6000 to 10000 K. The intensity of this emission is indicative of the concentration of the element within the sample.

Atomic Absorption Spectroscopy (AAS) is a spectral analytical procedure for the quantitative determination of chemical elements using the absorption of optical radiation (light) by free atoms in the gaseous state. AAS can be used to determine over 70 different elements in solution.

Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is a type of spectroscopy that uses the inductively coupled plasma to produce ions that travel though an electrostatic focuser to a mass analyzer and counted. As the charge of the focuser changes, different elements are allowed to reach the detector. The plasma operates at a temperature of nearly 10,000 C or 18,000 F.
