1.眼觀:均勻的細(xi)料結構的石材(cai)具有(you)細(xi)膩的質(zhi)感(gan),為石材(cai)之(zhi)佳(jia)品(pin);粗粒及不等(deng)粒結構的石材(cai)其外觀效(xiao)果較差(cha);
2.耳聽:質量好的(de)石材(cai)敲擊(ji)(ji)聲清脆悅耳;若石材(cai)內部存在輕微裂隙(xi)或因風化導致顆粒間(jian)接(jie)觸變松(song),則敲擊(ji)(ji)聲粗啞;
3.滴(di)(di)墨:在石材(cai)的背(bei)面(mian)滴(di)(di)上一小粒墨水(shui),如墨水(shui)很快(kuai)四處分散浸出,即表明石材(cai)內部顆(ke)粒松動(dong)(dong)或存在縫隙,石材(cai)質量不好;若墨水(shui)滴(di)(di)在原地(di)(di)不動(dong)(dong),則說明石材(cai)質地(di)(di)好。
