8 1/8 x 20 H Antique Round Glass Dome
This is an antique round glass dome that can restore your antique heirloom to it original. We acquire antique domes from all over the world to help you preserve your keepsake.
Most of the antique glass domes will have a paper tape on the bottom (or a visible trace of it once being there). The paper tape had two purposes. First if gave a slight cushion when setting the dome down. Second it covered the chipped bottom of the dome from it being cut to a particular height.
Most new round glass domes have a bead on the bottom. The bead gives greater strength to the glass. This bead is created by holding the glass dome at the top and rotating it while applying a gas flame near the point of its height. The glass melts at that point with the bottom dropping off and leaving a bead to seal the work. Oval glass domes do not have this bead generally since the flame can not be held in place as the dome rotates.
Many of our customers have the feeling that older glass domes will have more bubbles. This is generally not the case. It is the desire of all glass blowers to not have bubbles in the glass.
