Blenko Dalle de Verre - Tangerine

These tangerine dalle de verre slabs have a striking architectural presence. Even before they are cut and faceted, they possess many of the qualities that make slab glass so prized: saturated color, impressive thickness, and an extraordinary response to transmitted light.

Overall appearance

The glass portrays a deep tangerine to ember orange around its perimeter, with a radiant crimson-red core that seems to glow from within when backlit. The transition between the fiery orange edges and saturated ruby center creates remarkable optical depth, giving each slab the appearance of molten glass.

Because of their thickness, the color isn't simply on the surface, it appears to occupy volume. Light traveling through this glass produces a luminous, gemstone-like intensity unique to Blenko dalle de verre glass. 

Surface character

The slabs exhibit a richly textured cast surface with:

• Soft undulating ripples from the casting process

• Swirling internal striations

• Small entrapped air bubbles

• Occasional seed bubbles near the edges

• Slight variations in thickness that create shifting highlights

Rather than appearing perfectly smooth, the surfaces have an organic quality that scatters sunlight into glowing patches of scarlet, orange, and magenta.

Color behavior

The color changes dramatically depending on illumination:

• Direct sunlight: brilliant ruby center with incandescent orange borders.

• Diffuse daylight: warmer tangerine and vermilion tones emerge.

• Edge lighting: the perimeter becomes almost amber-gold while the center retains a saturated red glow.

This optical depth is one of the defining qualities of thick cast slab glass.

Individual observations

Landscape slab (first image)

A broad rectangular slab with a vivid crimson field framed by translucent amber-orange margins. The subtle horizontal layering near the base suggests natural settling during casting, while faint internal clouding gives the center a painterly quality.

Portrait slab (second image)

This taller panel emphasizes the vertical color gradient. The orange border is especially pronounced along the right edge, creating the effect of an illuminated frame surrounding the dense ruby interior.

Backlit example (fifth image)

The transmitted light reveals exceptional clarity and depth. Numerous tiny bubbles and internal textures become visible, demonstrating how the slab would produce sparkling refracted light once faceted for architectural work.

Artistic impression

These slabs evoke:

• glowing embers

• molten lava beneath cooling crust

• sunset through cathedral windows

• polished carnelian or fire opal

• illuminated parchment edged in gold

The palette is warm, dramatic, and highly expressive without becoming opaque.

Suitability for dalle de verre work

These slabs would be particularly effective for subjects involving:

• autumn foliage

• trees at sunset

• flames or phoenix imagery

• sacred heart or liturgical symbolism

• desert landscapes

• abstract geometric compositions

• modern architectural installations emphasizing warm light

Once faceted with a hammer and chisel, the orange edges would likely explode into brilliant flashes of gold while the red centers would refract as intensely saturated ruby, producing the jewel-like scintillation for which classic dalle de verre is celebrated.
