How to Judge the Quality of Marble for Home Decoration

When selecting marble for home decoration, understanding its quality is crucial. The quality of marble can be judged by appearance, processing quality, and mirror-like gloss.

I. Appearance Quality

Appearance quality includes defects such as missing edges, corners, cracks, color spots, lines, and pits. Marble slabs may also have warping, depressions, and stains. The inspection method is to place the slab flat and observe from a distance of 1.5 meters and 1 meter to see if there are visible defects.

II. Processing Quality

Processing quality is an important factor affecting the decorative effect of marble and is also the main basis for grading marble. It includes specifications and size tolerances (length, width, thickness), flatness tolerance, and angle tolerance. Based on the deviation of these indicators, slabs are divided into first-class products, second-class products, and qualified products.

III. Mirror-like Gloss

Gloss is referred to as mirror-like gloss in stone standards. The standard stipulates that mirror-like slabs should have a gloss that can clearly reflect objects. The gloss value should not be lower than 75 gloss units. The gloss value of different grades of marble slabs varies, and consumers can specify the required gloss value in the contract according to their needs.

Conclusion

When purchasing marble, specify the required grade in the contract to avoid vague descriptions such as "meeting national standards". Understanding the quality evaluation standards of marble can help consumers choose products that suit their needs.
