采用铅硼硅熔决釉研制出同时符合普通粘土瓦坯的烧成温度低、热膨胀系数低这两个主要性能特点的釉料。

The color glaze of low firing temperature and low expansion coefficient, to match the glaze tile made from common clay, was prepared in lead borosilicate system.

结果证明，硼质釉料无毒、性能优良、成本低，完全可取代有毒的铅质釉。

Results of practice show that boron glaze is of high-performance, non-poisonous and low cost. So it is able to substitute for lead glaze.
