How the Melt Works
An induction furnace uses a high-temperature electric current to melt metal with an added fluxing agent such as borax, which assists the metal to become molten and homogenous. Once molten, the metal is stirred so the alloying conditions are fully mixed into the melt.
Sampling can be done using glass vacuum pin tubes prior to the pour, or by drilling the bar after it has cooled. Material type determines the method.

Sampled in the Molten State
The molten metal can be sampled using a vacuum pin tube in the molten state, or drilled after the dore has been poured and the slag removed.
