板(ban)巖(yan)(yan)(yan)(yan)是(shi)(shi)具(ju)(ju)有板(ban)狀(zhuang)構(gou)造，基本沒(mei)有重結晶的(de)巖(yan)(yan)(yan)(yan)石，是(shi)(shi)一種(zhong)變(bian)(bian)質巖(yan)(yan)(yan)(yan)，原巖(yan)(yan)(yan)(yan)為(wei)泥質、粉(fen)質或中(zhong)性凝灰(hui)巖(yan)(yan)(yan)(yan)，沿板(ban)理方向可(ke)以剝成薄片。板(ban)巖(yan)(yan)(yan)(yan)的(de)顏(yan)色隨其(qi)所(suo)含有的(de)雜質不同而變(bian)(bian)化。板(ban)巖(yan)(yan)(yan)(yan)是(shi)(shi)具(ju)(ju)特征的(de)板(ban)狀(zhuang)構(gou)造，淺變(bian)(bian)質巖(yan)(yan)(yan)(yan)由(you)粘土質、粉(fen)砂質沉(chen)積巖(yan)(yan)(yan)(yan)或中(zhong)酸性凝灰(hui)質巖(yan)(yan)(yan)(yan)石、沉(chen)凝灰(hui)巖(yan)(yan)(yan)(yan)經輕微變(bian)(bian)質作用形成。

板(ban)巖在家居中的(de)(de)普及(ji)，包括(kuo)在室內(nei)外很(hen)大程(cheng)度上(shang)要歸功(gong)于板(ban)巖的(de)(de)審美價值(zhi)。其獨特的(de)(de)表(biao)面(mian)提供(gong)了豐(feng)富多樣的(de)(de)設計和色彩，而所有這(zhe)些都是(shi)自(zi)然(ran)天成的(de)(de)。磚(zhuan)與磚(zhuan)之(zhi)間各不(bu)(bu)相同(tong)(tong)，這(zhe)就使(shi)浴(yu)室變得(de)不(bu)(bu)一(yi)樣。然(ran)而不(bu)(bu)同(tong)(tong)的(de)(de)色彩與設計卻不(bu)(bu)會(hui)導致不(bu)(bu)協(xie)調的(de)(de)圖案。事實上(shang)，這(zhe)只(zhi)會(hui)增加板(ban)巖磚(zhuan)的(de)(de)美感，因(yin)為它(ta)們帶給人們的(de)(de)是(shi)一(yi)種不(bu)(bu)一(yi)樣的(de)(de)感覺，這(zhe)是(shi)其他地板(ban)磚(zhuan)所達不(bu)(bu)到的(de)(de)，即使(shi)同(tong)(tong)樣為天然(ran)石材磚(zhuan)。

之所(suo)以說板(ban)(ban)(ban)巖(yan)(yan)(yan)磚是(shi)(shi)用(yong)(yong)于浴(yu)室的(de)(de)理想材(cai)料還有另(ling)一個主(zhu)要優(you)點，那就是(shi)(shi)它非常耐磨。這也是(shi)(shi)很多人(ren)建議在(zai)(zai)高人(ren)流(liu)區安裝板(ban)(ban)(ban)巖(yan)(yan)(yan)地(di)(di)板(ban)(ban)(ban)的(de)(de)原因。在(zai)(zai)一些(xie)(xie)情況(kuang)下，有些(xie)(xie)業(ye)主(zhu)會(hui)(hui)抱(bao)怨板(ban)(ban)(ban)巖(yan)(yan)(yan)地(di)(di)板(ban)(ban)(ban)上(shang)會(hui)(hui)出現“交通圖(tu)”，即頻繁人(ren)流(liu)走動(dong)導(dao)致板(ban)(ban)(ban)巖(yan)(yan)(yan)磨損形(xing)成坑洼。這是(shi)(shi)不(bu)符合事實的(de)(de)。必(bi)須指出的(de)(de)是(shi)(shi)造(zao)成這個“交通圖(tu)”的(de)(de)原因是(shi)(shi)定期用(yong)(yong)于板(ban)(ban)(ban)巖(yan)(yan)(yan)磚上(shang)的(de)(de)養(yang)護劑。要知道這種(zhong)特殊地(di)(di)板(ban)(ban)(ban)磚的(de)(de)護理，必(bi)須記錄(lu)下所(suo)使用(yong)(yong)的(de)(de)養(yang)護劑以了解哪(na)種(zhong)類(lei)型能與哪(na)種(zhong)兼容。
