玻(bo)(bo)璃(li)的(de)历史与发(fa)展可(ke)以(yi)追溯(su)到(dao)公元(yuan)(yuan)000年左(zuo)右的(de)古埃及和(he)古巴比伦时期。当(dang)时的(de)玻(bo)(bo)璃(li)主要(yao)用于制(zhi)(zhi)(zhi)作珠宝和(he)装饰品(pin)。随着时间(jian)的(de)推(tui)移，人(ren)(ren)们(men)逐渐掌(zhang)握了玻(bo)(bo)璃(li)的(de)制(zhi)(zhi)(zhi)作技术，玻(bo)(bo)璃(li)制(zhi)(zhi)(zhi)品(pin)的(de)种(zhong)类也越来越多(duo)样化(hua)。在公元(yuan)(yuan)1世纪(ji)，罗(luo)马(ma)人(ren)(ren)发(fa)明了玻(bo)(bo)璃(li)窗，使得建筑物内部可(ke)以(yi)有充足的(de)光线。中世纪(ji)时期，威(wei)尼斯(si)成为玻(bo)(bo)璃(li)制(zhi)(zhi)(zhi)造业的(de)中心(xin)，威(wei)尼斯(si)玻(bo)(bo)璃(li)工匠们(men)创造了许多(duo)精美的(de)玻(bo)(bo)璃(li)制(zhi)(zhi)(zhi)品(pin)。到(dao)了19世纪(ji)，工业的(de)推(tui)动(dong)下，玻(bo)(bo)璃(li)制(zhi)(zhi)(zhi)造业得到(dao)了进一步发(fa)展，玻(bo)(bo)璃(li)的(de)生产成本大幅降低，玻(bo)(bo)璃(li)制(zhi)(zhi)(zhi)品(pin)开(kai)始普及到(dao)大众生活中。
