Cobalt Blue Glass Demitasse Cup

The item is a small, handled cup rendered in a vibrant, translucent cobalt blue glass. It appears to be a demitasse size, suitable for espresso or a small serving of tea or coffee, indicated by its apparent size relative to the hand holding it. The cup has a classic, rounded body with a clear, applied handle that is also cobalt blue. The glass itself exhibits a smooth, polished finish, reflecting light well, although there are noticeable white streaks or residue present on both the interior and exterior surfaces, especially prominent on the top rim and running down the side. This residue suggests either dried liquid, mineral deposits, or potentially paint/lacquer overspray, and would require cleaning to assess the true condition of the glass beneath. There are no obvious chips, cracks, or significant abrasions visible from the provided image. The construction appears to be machine-made, common for glassware, though without a clearer view of the base or manufacturer's marks, it's difficult to determine the exact origin or age. The rich, consistent cobalt blue color indicates the use of specific colorants in the glass-making process. The cup lacks any elaborate decorative elements, focusing instead on its essential form and striking color. The overall craftsmanship appears standard for utilitarian glassware, with no indicators of bespoke or high-art glassmaking. The style is relatively timeless, though the prevalence of cobalt blue glass in household items suggests it could range from mid-20th century to contemporary production.
