This Carlo Nason vase, consisting of two parts, is known as model S475. Taken together, the two vases read as a paired study in related contour rather than identical repetition. Their effect depends on the contrast between straight-edged rectangular openings and the rounded returns below, with the milky opalescent glass softening forms that are otherwise quite exact in outline.

Design
The vase is organised around two related silhouettes rather than two matching vessels. One vase is tall and comparatively narrow, with a vertical shaft that drops into a forward-projecting lower section; the other is wider and lower, with a broad rectangular body interrupted by a deep curved return and a small rectangular support beneath one side. Set together in the photographs, the two forms appear to answer one another through scale and reversal. The smaller piece rises from a compact base into a narrow upright volume, whereas the larger one spreads its mass laterally before turning down to meet the table through a more isolated support. That difference gives the pair a deliberate asymmetry when seen side by side.

Their openings are kept sharply legible. From above and at eye level, both mouths read as rectangular or nearly square, with straight edges meeting at clear corners and a thickened rim running continuously around the perimeter. Those crisp upper edges establish a geometric register that differs from the lower sections, where the walls bend inward and downward in a single rounded sweep. The shift from angular rim to curved return is especially clear on the larger vase, where the broad upper wall descends before folding into a deep inner curve above the supporting block. On the smaller vase the same principle is compressed into a tighter profile, so the outline resembles an L-shaped section with a softened inside corner.

The glass itself changes the reading of those forms. Rather than a clear transparent body, both vases are made in an opalescent pale blue-white glass with cloudy internal streaking visible across the walls. In broader views this gives the surfaces a cool, even appearance, but close photographs show milky variation and a lightly striated or feathered effect within the body of the glass. That internal movement stops the large plain sides from appearing flat or empty. Reflections remain soft rather than sharply mirrored, and the thicker rims and corners read slightly brighter at the edges, which helps define the profile against the background without breaking the muted tone.

Seen together from different angles, the pair shifts between reading as two independent vessels and as a coordinated exercise in repeated edge, curve and void.

Condition
Vintage condition with visible age and use. The supplied photographs show light surface wear and a few small dark specks or minor marks.
