几种常见情况 of Sesame White

Sesame white is now being used more extensively. As time goes by, various issues may arise, such as water spots, color variations, and white speckles.

Issue with Whitehua or crystallization disease

There is some white powder on the surface or in the gaps. If it's simply removed by hand, it may have been contaminated by efflorescence. Efflorescence is not always white; it can also appear as light gray, gray-black. Efflorescence on the surface of芝麻白 is relatively easy to remove, but if it occurs internally, cleaning becomes more troublesome.

The surface color has changed in hue.

This primarily occurs when colored adhesives are used during installation, with the colors seeping into the surface with moisture. If the exterior is completely yellowed, it may be due to the yellowing caused by surface treatment agents. If it is partially yellowed and the contrast and concentration vary, it may be due to rust yellow.

Surface water spot disease.

If there is an appearance of darkening, check for water spots first. Wet the surface of the sesame white with clean water and use a universal pH test strip to measure its pH. If it is alkaline, it indicates water spots; if not, it could be contamination. Common surface manifestations of water spots include: when touching the surface of the stone, it feels rougher, indicating that this condition might be due to alkaline water spots.
