Identifying Sesame Grey Burnt Noodles and Lychee Noodles

Hemp grey granite is a type of stone that is relatively common, often used for广场铺装广场铺装 and roadside paving. To provide anti-slip properties, there are two common finishes: hemp grey brushed finish and hemp grey荔枝面。What are the connections and differences between the two?

Identify whether it's a sesame fire cake or a sesame gray lychee by following these steps:

Pattern and Color: Place the composite board and the verified board flat on the ground, stand at a distance of 1.5 meters, and visually inspect.

2 Hand-carved Marks Lay the sheet flat on the ground, and visually measure from a distance of 1.5 meters.

3 Color Lines Estimate the number of color lines.

4. Corner Defects and Cracks: Measure the length, width, and angle of the defects using a caliper; visually count the number of corner defects.

5 Steps: Measure the angle of each step using a caliper, and the measured value will be the angle of the step.

Visible cracks are determined by visual inspection, while hidden cracks are identified using the hammering method (i.e., by striking the sheet with a metal hammer and discerning cracks through the sound, typically a dull sound).

7 Spot Size: Measure the spot size with a caliper and visually count the number of spots.

That wraps up the differences between the fire-finished sesame grey granite and the lichee granite. Hope this helps!
