Cased glass–vintage era canes and buttons
Background/Story
Cased glass buttons are not common and often misunderstood. Â Color determination may be tricky, since they are molded from a cane that is bi-color. Â The cane’s core determines how the button is classified as to color, regardless of the predominant color that shows on the surface. Â A cross-section view of the cane makes this concept easier to visualize. Â Canes made of contrasting colors will result in bi-color buttons, the “base color” coming from the inner core color of the cane, the other from the outer thin layer on the core. Â It is much like having a built-in decorative overlay. Â Some types of vintage glass made in Germany and the Czech Republic came from cased canes. Â Satin glass, moonglows, and DIGS (design in glass surface) are the main examples. Â Single color moonglows and satin glass utilized canes with a color core cased with clear colorless glass. Â It is the clear colorless glass that adds the translucent quality these buttons.
The leaf and swan designs shown below are both classified as black glass buttons. Â Planing off or “shaving” the molded surface design brings out the contrasting color scheme for best dramatic effect. White and black canes, paired with a contrasting color casing, are the most common.
