Materials & Craft — The Materials Behind CasaOmni

At CasaOmni, we are guided by a principle we call Material Honesty — the belief that the materials in your home should be exactly what they appear to be. No veneers pretending to be solid wood. No resin masquerading as stone. No plastic dressed as ceramic. Every material we work with is chosen for its authentic character, the way it ages, and what it contributes to a considered home.

This page is a guide to the core materials across our collections — walnut, brass, opal glass, and more — including where they come from, how they behave, and why we chose them.

Walnut

American Black Walnut (Juglans nigra) is one of the most prized hardwoods in furniture making. Its deep, chocolate-brown tones, fine straight grain, and natural luster make it immediately recognizable — and genuinely beautiful in contemporary interiors.

Hardness: 1,010 lbf (Janka scale) — hard enough for furniture, workable enough for fine joinery
Character: Rich warm brown with occasional purple or grey undertones; grain varies from straight to slightly wavy
Aging: Walnut lightens slightly with age and UV exposure, developing a warm honey-brown patina over time
Why we use it: No other hardwood offers the same combination of visual warmth, workability, and contemporary elegance. Walnut pairs exceptionally with linen, brass, and travertine — the core CasaOmni material palette.

Care: Oil annually with food-safe furniture oil. Avoid prolonged sun exposure. See our Care Guide for full instructions.

Oak

European and American White Oak are the foundation of our lighter wood pieces. Oak’s open grain, pale warm tone, and exceptional durability make it the most versatile hardwood in contemporary furniture.

Hardness: 1,290 lbf (Janka) — harder than walnut, highly resistant to daily wear
Character: Pale golden-beige with pronounced medullary rays (the characteristic ‘fleck’ pattern) in quartersawn cuts
Aging: Oak darkens and warms beautifully over time, developing a golden amber tone with age and light
Finish options: Raw / lightly oiled (natural), white-oiled (Scandinavian tone), or smoked (dark, contemporary)
Why we use it: Oak works with virtually every interior palette. Its strength and grain pattern reward both minimalist and warmer, layered aesthetics.

Travertine

Travertine is a form of limestone formed by mineral springs, characterized by its distinctive porous surface, natural fossil inclusions, and warm, creamy palette ranging from ivory to walnut-brown.

Origin: Primarily Italy, Turkey, and Iran — our travertine is sourced from established quarries with responsible extraction practices
Character: Natural voids, veining, and fossil inclusions are intrinsic to the stone — no two slabs are identical
Finish types: Filled & honed (smooth, sealed), unfilled (natural texture visible), or polished (high sheen)
Why we use it: Travertine captures the organic, tactile quality that defines the CasaOmni aesthetic better than any manufactured surface. It ages with grace and connects contemporary interiors to something genuinely ancient.

Care: Seal annually. Clean with pH-neutral products only. See our Stone Care Guide.

Brass

Brass — an alloy of copper and zinc — has been used in fine metalwork and fixtures for centuries. Its warm golden tone, workability, and ability to develop character over time make it the ideal hardware and accent metal for contemporary warm interiors.

Types we use: Unlacquered (living finish) and lacquered (stable finish)
Unlacquered brass: Develops a natural patina over months and years — deepening in tone, revealing the copper beneath in high-touch areas. Many designers consider a well-aged brass piece more beautiful than a new one.
Lacquered brass: Maintains its bright golden appearance indefinitely. Lower maintenance; does not patina.
Why we use it: Brass adds warmth and visual weight to a space without coldness. It bridges the organic (wood, stone, linen) and the refined (glass, ceramic) in the CasaOmni palette.

Opal Glass

Opal glass is a milky, translucent glass achieved through the addition of fluorides or phosphates during the melting process. It diffuses light evenly and beautifully — eliminating harsh glare while maintaining full luminosity.

Light quality: Soft, even diffusion with no visible hotspot or filament glare — ideal for pendants, table lamps, and floor lamps
Character: Smooth, matte-white exterior with a warm inner glow when illuminated; varies slightly between mouth-blown and machine-made pieces
Hand-blown opal glass: Each piece has slight variations in thickness and form — the mark of genuine craft
Why we use it: Opal glass produces the warmest, most residential quality of light of any diffuser material. It is the preferred choice of lighting designers for spaces where light atmosphere matters most.

Linen

Linen — woven from the fibers of the flax plant — is one of the oldest and most sustainable natural textiles. Its combination of texture, breathability, durability, and effortless elegance makes it the defining upholstery fabric of the CasaOmni collection.

Character: Slightly textured, naturally slubby surface; warm neutral tones that complement wood and stone
Durability: Linen is stronger than cotton and becomes softer and more supple with each wash and use
Aging: Linen develops a beautiful relaxed quality over time — it looks more ‘lived in’ in the best possible sense
Grades: We specify medium-weight upholstery linen (300–400 gsm) for sofas and chairs; lighter weights for cushions and bedding
Why we use it: Linen is the textile equivalent of honest materials — unpretentious, beautiful, and built to last. It is impossible to fake convincingly, which makes its presence in a room immediately apparent.

Ceramic

Our ceramic objects — vases, tableware, decorative pieces — are primarily high-fired stoneware and porcelain from established craft producers. High-firing (above 1,200°C) produces a dense, durable body with rich, complex glazes that cannot be replicated at lower temperatures.

Stoneware: Dense, tactile, slightly textured. The material of choice for objects that should feel substantial and grounded.
Porcelain: Finer, smoother, translucent when thin. Suitable for refined tableware and delicate decorative pieces.
Glazes: We favor matte, satin, and reactive glazes that vary across the surface — reflecting the kiln’s influence and the maker’s hand.

Our Commitment to Material Honesty

Every material in the CasaOmni collection is chosen because it is genuinely what it appears to be, performs as expected, and ages with integrity. We do not use materials that imitate others. We do not use finishes that disguise poor construction.
