Mirrors were invented around 8,000 years ago, long before glass existed. The earliest known mirrors were discs of polished volcanic stone made in Anatolia (modern-day Turkey) around 6000 BC. Everything since — the bronze hand mirrors of ancient Egypt, the jealously guarded glass of Renaissance Venice, the 1835 chemistry that made mirrors cheap, and the flawless float glass leaning against your wall today — is one long story of people chasing a clearer, truer reflection.
Here is that story in order, from a polished black stone to the modern full length mirror, and what the whole journey tells you about choosing a good one now.
A short timeline of the mirror
If you only read one thing, read this. Each leap solved the same problem the last one left behind — a truer image, in more homes, for less money.
| Era | Roughly when | The breakthrough | What it was made of |
|---|---|---|---|
| Obsidian mirrors | ~6000 BC | The first reflective surface you could hold | Polished volcanic glass (stone) |
| Bronze & copper | ~2900 BC – 200 BC | Shaped, portable hand mirrors | Polished metal discs |
| Venetian glass | 15th–16th century | Glass backed with a reflective layer | Glass + tin-mercury amalgam |
| The silvering revolution | 1835 | Cheap, bright, non-toxic mirrors | Glass + a thin layer of real silver |
| Modern mirrors | 1950s – today | Perfectly flat, distortion-free glass | Float glass + aluminium or silver coating |
When were mirrors invented? Obsidian, around 6000 BC
The first mirrors were not glass at all. As far back as around 6000 BC — roughly 8,000 years ago — people in Anatolia ground and polished obsidian, a naturally occurring volcanic glass, until its dark surface threw back a dim reflection. Archaeologists have found these polished obsidian discs in graves at Çatalhöyük, one of the world's oldest known settlements.
- Heavy and rare: obsidian mirrors were precious objects, owned mostly by the wealthy for grooming and decoration.
- More than a mirror: the dark, almost bottomless reflection gave them a mystical reputation. "Black mirrors" of polished stone turn up again and again in ancient ritual and divination.
The reflection was real but dim and a little distorted — the surface could never be perfectly flat. That limitation is exactly what every later innovation set out to fix.
Bronze and copper mirrors: the first portable reflection (2900 BC – 200 BC)
The next leap was metal. From around 2900 BC the Egyptians, and later the Chinese, cast and polished bronze and copper into mirrors bright enough to use every day.
- The shape that started it all: these were usually small, round discs with a handle of wood, metal or ivory. The round mirror is the oldest mirror shape there is — and, several thousand years later, still one of the most popular.
- Still a status symbol: more people could own one than in the obsidian age, but a polished bronze mirror was a sign of wealth and care.
The Lighthouse of Alexandria (around 280 BC)
Mirrors were not only for grooming. The famed Lighthouse of Alexandria, one of the Seven Wonders of the Ancient World, is said to have used a large curved metal mirror to throw the light of a fire far out to sea, guiding ships home at night — an early hint at how powerfully a curved mirror can gather and direct light.
Archimedes and the "burning mirrors" (around 212 BC)
The most famous mirror legend belongs to the Greek mathematician Archimedes, who is said to have defended Syracuse by arranging polished mirrors to focus sunlight onto Roman ships and set them alight. Modern experiments — including a well-known MythBusters attempt — suggest it would have been very difficult in practice. True or not, the story shows how long people have been fascinated by what a mirror can do.
The Venetian breakthrough: the first glass mirrors (15th–16th century)
The mirror you would recognise today — glass with a reflective backing — was perfected in Renaissance Italy, on the island of Murano in Venice. Venetian glassmakers learned to back a sheet of clear glass with a reflective amalgam of tin and mercury, producing a brighter, sharper image than any polished metal.
- Worth more than paintings: a fine Venetian mirror was a genuine luxury, affordable only to nobility. Venice guarded the technique so closely that revealing it could cost a craftsman his life.
- A hidden cost: the mercury in the amalgam was slowly poisoning the people who made them. "Mad as a hatter" hazards were not limited to hat-makers — mirror artisans paid the same price.
By the late 1600s, mirrors had become a statement of power — Louis XIV lined the Hall of Mirrors at Versailles with 357 of them precisely because they were so extravagantly expensive.
Who invented the modern mirror? The 1835 silvering revolution
The modern mirror was effectively invented in 1835 by the German chemist Justus von Liebig, who worked out how to deposit a thin, even layer of real metallic silver onto glass using a chemical reaction. It changed everything.
- Clearer: silvered glass reflected far more light, and far more truly, than a tin-mercury surface.
- Safer: it removed toxic mercury from the workshop.
- Affordable: for the first time, a good mirror was something an ordinary household could own rather than a treasure for the few.
This is the moment the mirror stopped being a luxury and became furniture. It is also where two of the choices you still make today were born — how the glass is silvered, and how well that silvering is protected. We dig into the first in our guide to double silver versus single silver mirrors.
How modern mirrors are made today
Today's mirrors are the quiet winners of the whole story: bright, true, durable and inexpensive. Two twentieth-century advances got us here.
Float glass (from the late 1950s) is the unsung hero. By floating molten glass on a bed of liquid tin, manufacturers could make sheets that are perfectly flat for the first time in history. Flat glass is the reason a modern mirror gives a true, undistorted reflection instead of the funhouse waviness of older plate glass — the physics of which we cover in why your reflection looks wavy.
The reflective coating is now applied by vacuum deposition — vaporised aluminium (or silver) bonds directly to the cooled glass, then protective layers of paint seal it against moisture and wear. Done well, it resists the cloudy black spots, known as "foxing," that you see creeping in from the edges of old mirrors where the silvering has failed.
One curiosity from the same era: front-surface mirrors, where the coating sits on the front of the glass rather than behind it. They eliminate the faint secondary reflection you get through glass, which is why they are used in telescopes, cameras and scientific instruments — but they are too delicate for everyday use, which is why your bathroom mirror is still silvered on the back.
What makes a good modern mirror (and what we look for)
Knowing the history makes it much easier to judge a mirror today, because every quality marker is the answer to a problem someone solved along the way. C&F Creation is NZ designed and NZ owned, and these are the things we look for in the mirrors we choose to carry:
- Flat float glass for a true, undistorted reflection — the float-glass payoff. A good mirror should reflect a straight door frame as a straight line, edge to edge.
- Low-iron glass where colour accuracy matters. Standard glass carries a faint green tint from its iron content; low iron glass reflects truer whites and skin tones. We cover the difference honestly in our guide to low iron versus standard glass.
- A well-protected reflective coating with sealed edges, so the silvering resists the moisture and salt air that cause foxing — a real consideration in humid and coastal New Zealand homes.
- A frame and fixings suited to how you will use it — a slim leaner for a bedroom, a wall mounted round for a living room, an anchor strap for a tall freestanding mirror near children or pets.
None of that is about superlatives. It is just the accumulated lessons of 8,000 years, applied to a mirror you will actually live with. If you are weighing up which to buy, our guide to mirror types and the mirror size calculator are the practical next steps.

Why the history of mirrors still matters
For most of human history, a clear, true, full length reflection was a luxury reserved for the wealthy. The reason you can lean an honest, distortion-free mirror against your bedroom wall for the price of a nice dinner is 8,000 years of incremental problem-solving — from obsidian to bronze to Venetian glass to silver to float glass.
It also explains why mirrors can feel so different from one another. The clarity of the glass, the colour the silvering returns, even how a mirror is lit, all change what you see — which is the subject of our most-read piece, why you look different in different mirrors. The history is the same reason the differences exist.

Frequently asked questions
When were mirrors invented?
The first mirrors were made around 6000 BC — roughly 8,000 years ago — from polished obsidian, a natural volcanic glass, in Anatolia (modern-day Turkey). Glass mirrors as we know them, with a reflective backing, were not perfected until Renaissance Venice in the 15th–16th century, and the modern bright, affordable mirror dates from the silvering process invented in 1835.
Who invented the modern mirror?
The German chemist Justus von Liebig is credited with inventing the modern mirror in 1835, when he developed a way to deposit a thin, even layer of metallic silver onto glass. His silvering process made mirrors clearer, removed toxic mercury, and made them affordable for ordinary households for the first time.
How were old mirrors made before glass silvering?
Before silvered glass, mirrors were made by polishing reflective materials. The earliest were polished obsidian stone; from around 2900 BC they were cast and polished bronze or copper discs. From the 15th century, Venetian glassmakers backed glass with a reflective tin-and-mercury amalgam — brilliant, but slowly poisonous to the craftsmen who made them.
What is an obsidian mirror?
An obsidian mirror is a piece of obsidian — a naturally occurring volcanic glass — ground and polished until its dark surface reflects an image. They are the oldest known mirrors, dating to around 6000 BC, and their deep, dim reflection gave them a long association with ritual and divination, which is why they are sometimes called "black mirrors."
Are modern mirrors made of silver or aluminium?
Most modern mirrors use a thin coating of aluminium, applied to the back of flat float glass by vacuum deposition and then sealed with protective paint; some still use silver. Both give a bright, true reflection. The flat float glass is what makes today's reflection distortion-free, and good edge sealing is what stops the silvering from clouding over time.
Why do old mirrors look spotty or cloudy at the edges?
Those black-edged blotches are called "foxing," and they happen when moisture creeps in and degrades the reflective coating, usually from the edges inward. It is why a well-made modern mirror seals its coating and edges carefully — especially important in humid and coastal New Zealand homes.
From a polished black stone to the flat, low iron glass leaning against your wall, the mirror has spent 8,000 years getting clearer and truer. Choosing a good one today is really just standing on the shoulders of everyone who solved the problem before you.
