玻(bo)(bo)璃的(de)(de)(de)(de)历史与(yu)发(fa)展(zhan)可以追溯到(dao)公元(yuan)000年左右的(de)(de)(de)(de)古埃及(ji)和古巴比伦(lun)时(shi)(shi)期。当时(shi)(shi)的(de)(de)(de)(de)玻(bo)(bo)璃主要用于制(zhi)(zhi)作珠(zhu)宝和装饰品。随(sui)着时(shi)(shi)间的(de)(de)(de)(de)推移，人们逐(zhu)渐掌握(wo)了玻(bo)(bo)璃的(de)(de)(de)(de)制(zhi)(zhi)作技术，玻(bo)(bo)璃制(zhi)(zhi)品的(de)(de)(de)(de)种类也越(yue)来(lai)越(yue)多(duo)样化。在公元(yuan)1世纪，罗马人发(fa)明了玻(bo)(bo)璃窗，使(shi)得(de)建筑物(wu)内部可以有充足的(de)(de)(de)(de)光线。中(zhong)(zhong)世纪时(shi)(shi)期，威尼斯(si)成(cheng)(cheng)为玻(bo)(bo)璃制(zhi)(zhi)造业的(de)(de)(de)(de)中(zhong)(zhong)心，威尼斯(si)玻(bo)(bo)璃工匠们创造了许(xu)多(duo)精美的(de)(de)(de)(de)玻(bo)(bo)璃制(zhi)(zhi)品。到(dao)了19世纪，工业的(de)(de)(de)(de)推动下，玻(bo)(bo)璃制(zhi)(zhi)造业得(de)到(dao)了进一(yi)步发(fa)展(zhan)，玻(bo)(bo)璃的(de)(de)(de)(de)生产成(cheng)(cheng)本大(da)幅降低，玻(bo)(bo)璃制(zhi)(zhi)品开始普及(ji)到(dao)大(da)众(zhong)生活中(zhong)(zhong)。
