钒作为玻璃着色剂，其作用很像铬。通常它导致绿色色调，这是由于三价钒的绿色和五价钒的黄色的叠加。大量过量的碱导致形成无色的钒酸盐。在特定条件下，可采用日晒法使二价钒呈淡紫色。讨论了熔化条件和基础玻璃成分变化对颜色的影响。
Vanadium, as a glass colorant, acts much like chromium. Ordinarily it leads to green tints which are due to the superposition of the green of trivalent vanadium and the yellow of pentavalent vanadium. Large excess of alkali leads to the formation of colorless vanadates. Under special conditions, solarization may be used to develop the lavender color of bivalent vanadium. The effect of melting conditions and changes in the base glass composition on the colors is discussed.
