無鉛玻璃和有鉛玻璃如何分辨

無鉛(qian)(qian)(qian)玻(bo)(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)和(he)有(you)(you)鉛(qian)(qian)(qian)玻(bo)(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)如(ru)何(he)分辨？　　1.看標(biao)識(shi)：　　無鉛(qian)(qian)(qian)玻(bo)(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)杯(bei)一(yi)般含(han)鉀，多(duo)為工藝品并在(zai)(zai)外包(bao)裝上有(you)(you)標(biao)識(shi)；而含(han)鉛(qian)(qian)(qian)玻(bo)(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)杯(bei)則含(han)鉛(qian)(qian)(qian)，即在(zai)(zai)一(yi)些(xie)超市和(he)地攤上常見的水晶(jing)玻(bo)(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)器皿，其(qi)氧化鉛(qian)(qian)(qian)的含(han)量可(ke)達24%.　　2.看色澤：　　無鉛(qian)(qian)(qian)玻(bo)(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)杯(bei)比(bi)傳(chuan)統(tong)含(han)鉛(qian)(qian)(qian)水晶(jing)玻(bo)(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)杯(bei)有(you)(you)更(geng)(geng)好的折(zhe)光性(xing)(xing)，更(geng)(geng)完美的展現了金(jin)屬玻(bo)(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)的折(zhe)光性(xing)(xing)能(neng)；如(ru)一(yi)些(xie)各種造型的擺件、水晶(jing)酒杯(bei)、水晶(jing)燈等等就是(shi)由含(han)鉛(qian)(qian)(qian)玻(bo)(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)制成的。看耐熱(re)性(xing)(xing)：玻(bo)(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)杯(bei)一(yi)般都可(ke)以耐很高的溫度，但是(shi)一(yi)般耐極(ji)冷(leng)熱(re)性(xing)(xing)能(neng)差。無鉛(qian)(qian)(qian)水晶(jing)玻(bo)(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)屬于高膨脹系數的玻(bo)(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)，耐極(ji)冷(leng)熱(re)性(xing)(xing)能(neng)更(geng)(geng)差一(yi)點，如(ru)果在(zai)(zai)特別冷(leng)的無鉛(qian)(qian)(qian)玻(bo)(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)杯(bei)中用開水泡茶容易發生爆裂(lie)。　　3.掂輕重：　　含(han)鉛(qian)(qian)(qian)水晶(jing)玻(bo)(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)制品與無鉛(qian)(qian)(qian)水晶(jing)玻(bo)(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)制品相(xiang)比(bi)，要(yao)略顯得厚重。　　4.聽聲(sheng)(sheng)音(yin)：　　超越含(han)鉛(qian)(qian)(qian)水晶(jing)玻(bo)(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)杯(bei)所(suo)發出的金(jin)屬聲(sheng)(sheng)，無鉛(qian)(qian)(qian)玻(bo)(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)杯(bei)的聲(sheng)(sheng)響更(geng)(geng)悅耳動聽，富有(you)(you)"音(yin)樂(le)"杯(bei)之美譽。　　5.看韌性(xing)(xing)：　　無鉛(qian)(qian)(qian)玻(bo)(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)杯(bei)比(bi)含(han)鉛(qian)(qian)(qian)水晶(jing)玻(bo)(bo)(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)杯(bei)更(geng)(geng)有(you)(you)韌性(xing)(xing)即耐撞(zhuang)擊(ji)性(xing)(xing)能(neng)。
