Overview
A classic example of American architectural glass featuring a central heraldic shield motif flanked by stylized scrolls. The window utilizes 'slag glass'—an opaque, marbled glass that was revolutionary for its ability to diffuse harsh sunlight into a warm, milky glow.
Story
Turn-of-the-century homes used these windows as 'jewels' for the house. They weren't for looking out, but for transforming the interior light. This shield design suggested a sense of lineage and permanence for the rising middle class.
Maker / Origin
While often unsigned, these were produced by skilled artisans in urban centers like Chicago, Philadelphia, or New York. Studios like Kokomo Opalescent Glass provided the raw sheets, which local craftsmen then hand-cut and leaded into custom patterns for residential builders.
Condition & Value
The window appears to be in its original rough-sawn wooden frame, which is a plus for collectors. There is visible dirt and soot buildup; professional cleaning would significantly brighten the glass. Any bowed lead or cracked panes would reduce value by 20-30%.
