Testing

Water Absorption:
0.15 - 0.34%
Density:
2670 - 2710 kg/m3
Flexural Strength:
12 - 15 MPa
Compressive Strength:
160 - 190 MPa
Stone texture:
a warm, earthy-toned natural stone characterized by a yellow to golden-beige base color, often interspersed with light brown, soft cream, and subtle grey mineral accents that create a naturally variegated and slightly dynamic appearance. Its visual effect is generally medium-contrast rather than strongly veined, with a gently mottled and granular pattern that gives the surface depth while maintaining an overall uniform and balanced look suitable for flooring, countertops, and wall applications. In terms of texture and structure, it is a coarse-grained, phaneritic granite composed mainly of interlocking quartz, feldspar, and minor dark minerals, forming a dense and durable crystalline framework typical of Brazilian granites. The grain is visible but not overly rough, producing a slightly speckled, natural texture that becomes more refined and glossy when polished, while still preserving the stone’s inherent mineral movement and structural strength typical of intrusive igneous rocks
