The cylindrical tectonic fracturing of the cylindrical lumber in the unprotected troupe (Snote: round bar) is absconded and results in a break in the surface when the cold pull occurs. The gold cortex erodes and the visible surface is darker and coarse crystall (figure 1.4-1). Microscope observations reveal that the surface of the specimen is a rough pelvis of about 0.50 mm deep, with cracks from the cold radial process (figure 1.4-2 ~ 1.4-3).
The specimens have overheating spherical, while the surface is particularly overheated, resulting in the fragmentation of the surface and the resulting fractures of the surface when cold-strangling is due to the poor plastic resilience of the rough-formed luminous surface.

(Note: Thermal rinse is repulsed with oxidated skin, with thin, detached pure iron layers on the surface, which is equivalent to a membrane, and acid washable. Not considered decarbonized)

(The carbon netless in the P-square of the sample indicates decarbonization, which is caused by high temperatures and not by the genetics of thermal rinsing.
The following are the products that will be used for gold phase:
1. FY-QG-65, a Fuyunkin co-moder, cut the sample gold and cut down a small piece, horizontal or vertical, as required by the sample, to facilitate mosaicing.

ii. Thermal mosaics of the gold co-sampling:
Fuyun Gold Cottage: Thermal compost FHM3 in the indentation to prevent the edge from being turned over, making it impossible to observe the edge.
Full Touch screen full-automatic mosaic FY-XQ-200

III. Kim's co-sampling:
Fuyun materials gold-specific sandpaper: 230mm diameter without glue 600# 1200# 2500#

III. LEAVE THE FIELDS OF THE KING PHOTOS:
Fuyun materials gold-phased photo fabric: 230 mm in diameter velvet/splendon
Fuyun materials, Fresco-Frestilt Spraying: 1/3 micrometre
Fuyun machine: manual in no-extreme-speed grinder
Pressure: Fixed, neutral, stable, without too much pressure.
Time: 2-5 minutes, whichever is the same, the scratches of the thin sandpaper are almost removed.
Rotation speed: 200 turns
Raarboard direction: Clockwise
During polishing: The polished rags need to be immersed early, the polished fluid is down in the centre position and handwashing is added to its lubrication.
Pour: A little bright, no scratches, and can move on.

Pouring: The brightness is very high.
Corrosion observation:
Gold-photo microscope (magnification multiple: 50X, 100X, 200X, 500X, 1,000X)

The following are used for corrosive reagents:
