Typically the glass in these windows is separated by lead glazing bars. Stained glass windows were popular in Victorian houses and some Wrightian houses, and are especially common in churches. [24]

[9] Two major methods to make window glass, the crown method and the cylinder method, were used until the process was changed much later in the 1920s.

The finished product has near-perfect parallel surfaces.
