玻(bo)璃(li)(li)的(de)历史与(yu)发展可以追溯到(dao)公元000年左右的(de)古埃及和(he)古巴比伦时期。当时的(de)玻(bo)璃(li)(li)主要用于制(zhi)作珠宝和(he)装饰品。随(sui)着时间的(de)推(tui)移，人们逐渐掌握(wo)了玻(bo)璃(li)(li)的(de)制(zhi)作技(ji)术(shu)，玻(bo)璃(li)(li)制(zhi)品的(de)种类也越来(lai)越多样(yang)化。在公元1世(shi)纪，罗马人发明了玻(bo)璃(li)(li)窗(chuang)，使得建筑物内(nei)部可以有充足的(de)光线。中世(shi)纪时期，威尼斯成(cheng)为玻(bo)璃(li)(li)制(zhi)造业的(de)中心，威尼斯玻(bo)璃(li)(li)工匠们创造了许多精美的(de)玻(bo)璃(li)(li)制(zhi)品。到(dao)了19世(shi)纪，工业的(de)推(tui)动下，玻(bo)璃(li)(li)制(zhi)造业得到(dao)了进一步发展，玻(bo)璃(li)(li)的(de)生(sheng)产成(cheng)本大幅降(jiang)低，玻(bo)璃(li)(li)制(zhi)品开始(shi)普及到(dao)大众生(sheng)活中。
