In post had previously been shown pictures of white color piropilit, grayish the post so on presented the piropilit brown color with reddish brown spots and piropilit white. The two minerals with different colors is found in the quarry's location in the village of piropilit Argotirto Sub Sumbermanjing, Malang. Piropilit reddish brown color and white spots of Brown piropilit this number is not as big a piropilit piropilit which is white and greyish white. Because of different color that is what makes "feel masel" curious
According to Dr. Sunaryo, S.Si., M.Si., Chairman of the Physics Department of
Geophysical Studies Programs FMIPA, Brawijaya University was unfortunate that the color red on the sides of piropilit comes from feldspar. Feldspar, piropilit also included in the Group of silicate minerals composed of aluminium and silica. This Mineral is the most common or most minerals found on Earth.
