New Round Glass Domes

New round glass domes are domes that are made today using in many cases the original molds that were used over 100 years ago.
There are two ways that round glass domes are made. The molten glass can be blown into a mold or it can be injected into a two part mold.
It is very difficult to tell the difference between a new dome and an antique dome because the quality is typically very good.
