A known chemical company is developing a patent for
a new variant of artificial stone composed mostly of quartz ( 93wt
and polyester resin . This company is launching a pilot plant where

to measure the degree of product homogeneity, 50 samples were taken,
performed 5 measurements per plate corresponding to different areas
of artificial stone Vickers hardness
