When looking for these styles, consider the quality – after all, cheaply made knobs can loose their luster quickly after installation. Worse, they tend to fall apart in your hand! Look for genuine steel spindles and solid brass shanks.

The original styles of these knobs date back to the early 18th century, when inventors discovered how to press molten glass into iron molds. The actual molds, termed ‘press molds’, were reusable and made from high-grade cast iron. Artisans would carve the knob geometry into the cast iron, and the molten glass would be pressed into the mold. Glass knobs originally became popular in the US after World War 1, driven primarily by a shortage of copper and brass.

Back in the day, glass door knobs were rated by facets – similar to how jewelers rate diamonds. The door knobs sported six to fourteen faceted sides and was bubbled in front to display the internal star burst.  Later, manufacturers began inserting mirrored cardboard in the back of the knob in order to better reflect light through the star burst design.

Although more rare, some styles of these knobs featured bright, vibrant colors like amber and violet. Another less well-known style was termed “Vaseline glass” and got it’s unique green-yellow color by adding uranium oxide to the glass. To the delight of little kids in the day, these knobs would glow brightly when exposed to a black light.
