半透明乳白色玻璃。在配料中加入乳浊剂，如萤石、冰晶石、氟硅酸钠、磷酸钙等。熔制时熔化于玻璃中，冷却时析出成无数极微小的悬浮晶粒而呈乳浊态，使光线散射，不完全透过，因而变得柔和。
结果表明乳浊玻璃中晶粒的数量随氧化铝的含量而增加。
The results show that the quantity of grain in opaque glass is increased with increasing the amount of aluminum oxide content.
探讨了乳浊玻璃化学组成对于玻璃乳浊度和坩埚侵蚀速度的影响。
Effects of chemical compositions on the glass opacity and the corrosion rate of glass pot have been studied.
为此，但只是治标不治本，要根本上防治氟化物的污染，在于用无氟乳浊玻璃。
But it is a temporary solution and if we want to control the fluoride pollution, we must use opaque glass with fluorine-free.
