Liangtaosha Stone, sourced from Lingxiang Pengbin Stone, introduces the surface erosion phenomenon of Liangtaosha stone: When touching the surface of Liangtaosha stone, if it feels rough, the marble (mainly composed of CaCO3) may have been eroded by acid; granite (mainly composed of SiO2) may have developed alkaline water stains followed by particle stripping. White efflorescence or crystallization on Liangtaosha stone: Check for white efflorescence, which appears as some white powder at the jointing or on the surface of the Liangtaosha stone, easily removable by hand.

Liangtaosha Stone Water Spots: The surface of Liangtaosha stone exhibits discoloration. To check for water spots, first wet the surface of the Hebei Liangtaosha stone with clean water, then use a universal pH test strip to measure its pH level. If it's alkaline (the test strip turns blue), it indicates water spots; otherwise, it may be oil contamination. For alkaline water spot contamination, even if the surface is heated with a gas spray, it's difficult to dry. If it's just caused by general moisture penetration, it dries and disappears easily.

Lantao Sandstone Surface Yellowing: The yellowing is not region-specific and may be caused by the surface treatment agent used, which leads to discoloration. Localized and concentrated yellowing on Lantao Sandstone Surface: The yellowing is localized and varies in intensity, resembling rust.
