Cobalt blue glass vase by Indiana Glass Company

This cobalt blue glass vase was produced by the Indiana Glass Company, likely during the mid-20th century (1950s-1970s). The piece features a distinctive bulbous shape with a flared rim and appears to be from their 'Illusions' or similar decorative line that was popular during this period. The deep cobalt blue coloration was achieved through the addition of cobalt oxide to the glass mixture during manufacturing. This type of decorative glassware became particularly popular in American homes during the post-war era when colorful glass accessories were fashionable interior decorating elements. Glass collectors and mid-century modern enthusiasts particularly value these pieces for their vibrant color and characteristic forms that exemplify mid-century American glassmaking techniques and aesthetic sensibilities.
