NUMARTIS Glass Surfaces · Mineral pigment washes on kiln-fired glass

Oxide Wash

About This Variant

Oxide Wash

Oxide Wash applies mineral oxide pigments to glass during the kiln-firing process, creating colour that is part of the glass structure rather than applied to its surface. The technique produces translucent colour fields of extraordinary depth — the pigment sits within the glass, giving the colour a three-dimensional quality that surface paint or film cannot replicate.

Available in a curated palette of mineral-derived colours: iron oxide produces warm ochres and deep terracottas; cobalt creates blues from pale sky to near-opaque indigo; copper yields turquoise through to deep verdigris. Custom colours are available for bespoke commissions. The wash technique allows colour gradients — areas of high concentration transitioning to transparent — for atmospheric large-format panels.

Why NUMAEX

Why NUMARTIS Glass Surfaces by NUMAEX

NUMARTIS surfaces are cast and fired in our atelier as a single piece — no joins to telegraph, no surface laminates to lift, no field-applied finishes to drift over time. The result is a continuous architectural surface with the depth of stone and the optics of glass. Every panel is calibrated to the wall it will live on, not to a catalogue specification.
