Felipe Derflinger Cobalt Blue Art Glass Tumbler Metal Cage Modernist Studio Glass 5.25 Inch

This striking hand blown glass tumbler by Felipe Derflinger features a vivid cobalt blue body enclosed within a sculptural metal cage sleeve. The design incorporates bold geometric elements including circles, squares, and triangles, creating a strong modernist composition with layered visual texture and industrial contrast.

Standing approximately 5.25 inches tall with a slightly tilted rim, the piece reflects a deliberate studio art approach where form and function merge into a single sculptural object. Natural glass bubbles are present within the cobalt body, consistent with hand blown production and adding to its organic character. The glass remains free from chips or cracks.

The surrounding metal cage shows a naturally aged patina, enhancing the contrast between the polished glass interior and the textured exterior framework. The overall design allows the piece to function as a drinking glass, small vase, or standalone collectible art object.
