Process

From vision to light sculpture

Each Forms In Nature piece is developed from a vision. Materials, light, and technical systems are built around that vision. The visual force of the work is never compromised.

01 — From vision to light sculpture

Each light sculpture slowly reveals itself

The vision is refined, discarded, corrected, and revealed until its form becomes clear. Materials, light, wiring, and technical systems are developed around that vision.

The visual force of the work is never compromised. The result is a light sculpture where reality has been shaped around the image.

02 — Casting in Riópar

Where casting, fire, and landscape still feel inseparable

The metal work is produced in Riópar, a remote mountain village in southern Spain where casting, fire, and landscape still feel inseparable. Riópar has carried a metalworking tradition since the 18th century, when the Royal Factories of San Juan de Alcaraz became one of Spain’s historic centers for brass and bronze production.

The village stands inside a forceful natural environment: caves, mountains, burned forests, heavy storms, winter snow, dry summers, and an intense return of life after destruction. This is not a decorative idea of nature. It is nature as pressure, danger, resistance, and renewal.

In that context, each organic form is transformed through casting. The original is lost. The gesture survives in bronze or brass.

03 — Mouth-blown glass

Each glass element is carefully designed as both a screen and a lens for light

Its thickness, weight, surface, curves, and small variations determine how the light is softened, distributed, and carried through the material. The studio works with a small number of controlled glass forms, each one mouth-blown and individually shaped by hand in a remote glass workshop near Istanbul.

Pío Díaz personally follows the glass production process, from heat control and resting time to blowing, molding, cutting, polishing, blasting, waxing, correction, and final light reflection tests.

The glasses are made from the same base form, but each one is slightly pushed, shaped, and corrected so no two pieces are exactly the same.

“I invest my interest and dedication digging out past forgotten memory hidden in the layers of our mental adaptations.”

Pío Díaz — artist and founder

Forms In Nature was founded in 2011 in Copenhagen. Every production decision — material, technique, finish — is made by Pío directly. The studio works with a small group of artisans trained over years of close collaboration.

This is not industrial production. Each piece is a consequence of the artist’s hand, eye, and accumulated knowledge.

Machined brass fittings

04 — Invisible precision

Every part belongs to the sculpture

Every part of a Forms In Nature lamp is developed around the work itself. The cables, bulbs, fittings, closures, suspension systems, surface treatments, wiring, and small mechanical details are designed or specified by Pío Díaz so they belong to the sculpture rather than appear as standard components added afterwards.

The suspension system is developed as part of the work: it has to hold, align, and support the piece while remaining visually calm and integrated.

No technical solution should compete with the sculpture. Nothing should feel too visible, too heavy, or too ordinary. Each solution is carefully crafted and refined until it disappears into the visual logic of the piece.

The result is a work that is highly technical, precise, and almost invisible.

05 — Light quality

Warm, present, calm, and distributed

Pío Díaz embraces rooms where the light is on. A very dark room asks the body to work harder. An overlit room creates the opposite problem: the light becomes too demanding, too active, too present.

Pío’s light theory is built around the space between those two conditions. The intention is to create a balanced form of illumination — warm, present, calm, and distributed.

The focus is on warm light, accurate color rendering, deep dimming, and stable light without visible flicker. The glass protects the eye from direct brightness and distributes the light softly through the room.

06 — Fine balance

Each piece is tested before it leaves the studio

The final calibration is personally made by Pío Díaz, adjusting light, glass, metal, surface, fittings, cables, suspension, shadow, warmth, and presence until the work reaches its balance.

This balance is both technical and emotional. The piece has to function with precision, but it also has to feel natural in the room.

The same gesture, different scale

In Weeds, Pío collected plants from the margins of Copenhagen and preserved them in glass cases — unwanted forms given permanence. In the collection, he does the same with branches and vines: finds what nature left, and fixes it in metal. The object and the artwork come from the same place.

Forest

A 360-degree arrangement that inverts natural logic

Forest encases a miniature world of branches, shrubs, and roots inside a luminous shell. The piece emphasizes what is usually buried — the root system — bringing it forward as the central form.

Crafted from PVO composite and 3D-printed with precision, each sculpture is part of a limited edition of 100. The light source is a dimmable halogen that renders the interior forest with warmth and depth.

15th anniversary edition. 20 original copies. A work that marks a moment rather than repeats a form.

Grapes Recast

The form of a grape cluster, reconceived in brass and glass

Grapes Recast takes the organic geometry of a fruit cluster and translates it into light. Each of the 13 glass spheres is positioned to replicate the natural grouping of grapes.

The structure is cast in brass with untreated steel available as an option. The glass is mouth-blown, giving each sphere a subtle individuality in thickness and translucency.

Dimmable from 100 to 2600 lumens. Wired for EU and USA. Made to order from Riópar, Spain.

Branches — atelier

How nature shapes each tree differently, like a vital fingerprint

Branches is born from a fascination: no two trees grow the same way. Every branch carries the record of its growth — the weight it held, the wind it resisted, the light it followed.

Each piece is cast from a real branch, rendered in investment cast bronze or brass. The original form is consumed in the process. What remains is metal with the exact memory of wood.

Every unit is singular and unreproducible. The form is not designed. It is found, cast, and fixed in light.
