First, raw materials are larger and need to be cut to facilitate the polishing of gold.

The sample needs to be embedded in a fuyun-like coheternary fHM3 for special materials with a high hardness, because the sample needs to measure the thickness of the edge. The gold-spectrum embedding machine is conditional on the automatic embedding machine, and the recommended product is as follows:

iii. Grain size of sandpaper for the fuyun gold: 240#, 600#, 1200# The machine also has a more effective use of the automatic gold grinder, as follows:

The product surface requires at least scratching, cleaning of the corrosive side, and drying of the surface with a blower.

The picture is as follows:

Corrosion observation:

Fuyun-phased and gold-phase microscopes (magnifying: 50X, 100X, 200X, 500X, 1,000X) are shown below:

The following are used for corrosive reagents:
