Columbia - Imperial
Columbia has no pattern other than eight exterior fluted sides and a base that ends in eight scallops. Under the base are also eight intaglio fluted elements. Columbia pieces were made from two separate molds but each has the same basic design.

The first has a dome type foot and a thick stem. These dome footed pieces can be found in three different shapes. Typically, it is seen in a vase shape similar to that above left. Heights and spread of the vase top do vary. The dome footed mold was also use to make cake plates and rose bowls. Vases are found in a range of colors including clambroth, green, marigold, purple and smoke. Cake plates and rosebowls are only found in marigold.

A compote with a thin stem, like the example shown to the far right, comes from another Columbia mold. These stemmed compotes are limited to clambroth or marigold.

Early Imperial Glass catalogs, as shown below, show Columbia as mold #246 and show various shapes found in crystal. In carnival only the vase, cake plate and rosebowl are known from the dome footed mold and the compote from the stemmed mold.
