Foundry, recovery, and refining department.

Our foundry uses both gas and induction melting furnaces to melt any type of metal or particular alloy.
The incinerator furnaces combined with mills and mixers allow the recovery of residues from goldsmith processing and from any activity that uses precious metals.
The refining process ensures the purity of the treated metals and the punching with fineness and trademark guarantee the declared fineness.

Analysis and Titration

The laboratory is equipped to carry out cupellation analyzes on ingots, rods and samples of objects. The analysis of the ashes is particularly accurate for the detection of all precious metals. Our spectrometers allow the non-destructive analysis of the samples through the study of X-ray fluorescence. These analyzes give the complete picture of the composition of the alloys in all its metallic components. ICP technology is used to search for specific components.

On request it is possible to create customized alloys for particular productions.
