Leaded glass may mean:

• Lead glass, potassium silicate glass which has been impregnated with a small amount of lead oxide in its fabrication. Apart from optical effects, glass may have lead added as an impediment to the transmission of radiation.
• Glass panels made by combining multiple small pieces of glass, which may be stained, textured or beveled, with cames. The most common example is stained glass windows.
• Flint glass, an optical glass that has relatively high refractive index and low Abbe number.
