When a mold is not available, we use air to blow the dome through a blow ring. This is called free-blowing.
Using blow rings allows us to manufacture domes in depths ranging from 1″ up to nearly 1/2 of the domes diameter.
(Example: A 20″ Dia. dome can be free-blown up to approx. 9.75″ deep)
Select a size based on the outside diameter of the dome.
