When specifying a wall mirror for a high-end residential interior, the category of aged glass introduces a distinction that is not always well understood at the briefing stage. The choice between an authentic hand-applied finish and a simulated one is not merely aesthetic: it is a specification decision with consequences for durability, visual behaviour under light, and the overall integrity of the interior. Mirrors with genuine antiqued glass represent a narrow and demanding segment of decorative production, one where process defines quality in ways that a specification sheet rarely captures. Understanding what differentiates authentic production from its imitations is the first obligation of any interior designer entering this category.
What makes an aged glass finish authentic
An authentic aged glass finish is the result of a hand-applied artisanal process carried out directly on the surface of the glass, piece by piece, without mechanical intervention. What this produces is a surface with tonal variation, visual depth, and controlled irregularities that are inherent to the material itself, not added to it. No two surfaces are identical, because no two applications of the finish are identical. This is not a quality claim: it is a structural consequence of the process.
A hand-aged mirror produced in this way reads differently under natural and artificial light than any reproduced or printed equivalent. The finish is not a layer applied over the glass: it is the result of working the glass directly. That distinction is what separates authentic production from the simulated finishes that dominate the wider market.
A manufacturer of custom decorative mirrors for interior designers who applies this standard will always work in an in-house workshop, under conditions that allow direct control over every stage of the process.
Why the process cannot be replicated mechanically
Simulated aged glass finishes exist in abundance and serve a different part of the market. They are produced using adhesive films, prefabricated coatings, or industrial printing processes. In photography, the result can appear convincing. Under direct observation, in the presence of considered lighting design, and over time, the difference becomes evident.
A prefabricated or printed finish applies a uniform or semi-uniform pattern to the glass surface. It does not interact with the glass itself. It does not produce depth. It degrades in ways that a hand-worked surface does not. And it cannot, by definition, produce a unique result: the same film or screen produces the same image on every unit.
The absence of mechanical process is what guarantees uniqueness in a hand-aged mirror. It is also what makes this category impossible to scale in the conventional sense. A high-end handcrafted mirror studio with an in-house workshop that works at this standard cannot accelerate production without abandoning the process that defines it. That constraint is not a limitation: it is the condition that makes the work meaningful within a serious interior.
When a standard size does not resolve the wall
Most residential specifications are resolved by a standard size, and there is no reason to complicate them. We produce a standard collection of sizes and formats, made to the same specification and with the same hand-applied finish as everything else that leaves the workshop.
The question arises where catalogues end. A mirror intended to anchor a monumental entrance hall, or a full length mirror designed for a private dressing room with specific proportional requirements, will not always align with a standard dimension. At that point most suppliers ask the designer to adapt the design to the object rather than the reverse.
Beyond our standard collection there are no restrictions of shape or size. Every dimension is possible. Every silhouette is possible. The mirror is made to the space, to the drawing, to the compositional decision of the project. This is what distinguishes a bespoke mirror practice from a retailer with a customisation option.
Having both routes is not a commercial position. It is the technical and operational condition that allows a mirror to function as an element of architectural design rather than as an object inserted into one.

Where our aged glass is made
JoverValls is a Spanish atelier specialising in handcrafted mirrors with antiqued glass, with our own workshop in Spain and a production practice built on over twenty years of accumulated expertise in hand-aged mirror production, incorporated formally through our Antique Boutique line in 2022. We are listed in the Homo Faber Guide by the Michelangelo Foundation, the international reference for European artisanal heritage, a presence that reflects the standard of craft we hold ourselves to.
We are present on 1stDibs, where our work reaches an international audience of collectors, interior designers, and private clients engaged in high-specification residential procurement. As a supplier of mirrors with antiqued glass for high-end residential projects, we work regularly with specifiers based in the United States, northern Europe, and beyond, integrating remote consultation and precise documentation into a workflow designed for international collaboration from the first contact.
A hand-aged glass mirror is a mirror in which the antiqued finish is applied by hand, directly on the glass surface, piece by piece, producing a unique result that no mechanical or printed process can replicate. We produce bespoke wall mirrors and full length mirrors in a standard collection of sizes and, where a project requires it, to any size and shape, with a hand-applied antiqued glass finish carried out in our own workshop in Spain. Wall fixings are supplied with every piece. The manufacturing lead time is six weeks from order confirmation, plus transport. Worldwide shipping is carried out with reinforced packaging developed specifically for the long-distance transport of large-format glass.
We serve both interior designers and specifiers acting on behalf of clients, and private clients commissioning a singular piece for their own residence. In both cases the standard is the same: manual execution and a surface that is unrepeatable by definition.
Frequently asked questions
What is the difference between real and simulated aged glass?
Authentic aged glass results from a hand-applied artisanal finish executed directly on the glass surface. Simulated finishes use adhesive films, prefabricated coatings, or industrial printing. The difference is visible under direct observation and in the behaviour of the surface under light. A hand-applied finish produces depth and tonal variation that is inherent to the glass. A simulated finish applies a reproducible pattern over it. Over time, the two behave differently: the hand-worked surface does not degrade in the same way as a film or printed coating.
Can I order any size or shape?
Yes. We offer a standard collection of sizes and formats that resolves most residential specifications, and we also produce mirrors to any size and shape, with no dimensional or formal restrictions. If the standard range does not resolve your wall, the piece is made to your exact measurement. Further details on available configurations are available on the bespoke wall mirrors collection page.
Do you ship internationally?
Yes. We ship worldwide, using reinforced packaging developed for the transport of large-format glass over long distances. We work regularly with specifiers and private clients in the United States, northern Europe, and other international markets.
What fixings are included with each mirror?
We supply wall fixings with every piece we make, regardless of size or format.
How long does production take?
The manufacturing lead time is six weeks from order confirmation. Transport time is additional and varies according to the destination.
See our hand-aged mirrors
For interior designers and specifiers working in high-end residential contexts, we make mirrors with a hand-applied antiqued glass finish, in standard sizes and made to measure, produced in Spain. Consultations are open to specifiers and private clients internationally.
You can see the finish across the range on our bespoke wall mirrors collection, or request a Private Consultation to discuss the dimensional, formal and finish requirements of your project. We provide a precise specification and a confirmed lead time from the first enquiry.
