Bronze casting, plaques & architectural restoration · the Old Crucible & Temple Gate · Est. 1996

Two thousand degrees, poured slowly.

Lostwax casts bronze the slow way — a wax model invested in ceramic, burned out over two days, and filled with molten silicon bronze in a single pour. Commemorative plaques, architectural hardware, monuments and the parts nobody else can replace — cast, chased and patinated by the same hands.

The historical society wanted a replacement door pull for a building that outlived its own foundry. Lostwax cast it from photographs and one broken original — the weight, the patina, the whole grammar of the thing. Two committees have since approved it and neither believed it was new.

Our father’s memorial plaque is the reason I can read his handwriting again. They cast his signature off a letter, chased it by hand, and the bronze sits in the garden gaining the exact green it is supposed to gain. The pour day invitation was the most extraordinary thing I have been asked to attend.

As an architect I specify machine-cut bronze all day and it arrives dead. This shop is the other thing: a balustrade section with a hand-chased surface that throws light like water. The building won an award and the metal is half of why.

The casting trades

Services

Four doors into the foundry

01

Commemorative plaques & markers — from $1,850

Cast silicon bronze to your text and drawings — signatures, seals, maps — with hand-chased letterforms and a patina chosen for the site it will age in. Dedication-ready mounting, foundry-marked on the reverse, and a wax copy you keep before the burnout takes it.

02

Architectural castings & hardware — from $640/pattern

Door pulls, push plates, balustrade fittings and the ornament a century building lost a piece of. Patterns made from photographs, originals or the surviving half of a pair — cast to match weight and finish, chased to match age.

03

Monument & sculpture casting — quoted per commission

The sculptor’s route: moulds taken from your original, waxes chased under your eye, and the pour scheduled on a day you can stand at the crucible. Full service from armature advice to the final hot patina, in bronze to your alloy specification.

04

Restoration & recasting — from $2,200

Broken monuments, damaged plaques, missing hardware: the piece moulded, the missing cast, the whole reintegrated and patinated to match its own surviving surfaces. Repairs in metal, never in filler — the next restorer inherits bronze, not epoxy.

The pour book

Six castings from the last two seasons, from a door pull to a full monument — each photographed after the chase and again after the patina had a season to settle. Bronze does not finish; it begins.

  1. Week 1

    The model

    Wax carved, printed, or moulded from your original — whichever the piece needs — with the details chased by hand because moulds flatter nothing. You approve the wax in person or by courier before anything is invested.

  2. Weeks 2–3

    The investment & burnout

    The wax is dipped in ceramic slurry nine times, stuccoed and dried, then burned out over two days until the shell is empty and the pattern’s ghost is exact — the “lost” in lost-wax is literal, and it is why every casting is one of one.

  3. Pour day

    The pour

    Silicon bronze at 1,900 degrees, degassed and poured in one continuous moment while the shell is hot. Clients are invited, at distance, with the foundry’s own pour crew on the crane. It is over in ninety seconds and it is not forgettable.

  4. Weeks 4–5

    Chase & patina

    The casting cut from its shell, sprues removed, surfaces chased by hand, and the patina built with heat and chemicals to the green, brown or honey the site asks for — then waxed, signed and dated on the reverse.

  5. Delivery

    The installation drawings

    Mounting templates, anchor schedules and the care sheet for the finish you chose — including the honest instruction for living bronze: touch it, and let it darken where the hands fall.

Slow is the process, not the waiting

A casting takes six to eight weeks because each stage is a physical fact: wax must yield, ceramic must dry, bronze must flow once. Nothing in the sequence can be hurried without being cheapened — the calendar is the recipe, and the pour day is worth the whole wait.

Every other shop offered to cut it from plate and call it cast. Lostwax burned out a two-day shell and poured it in ninety seconds, and when I held both samples the difference was the difference between a photograph and a person. The bronze remembers being liquid. You can feel it.

Asked at every wax approval

Lost-wax or sand casting — what is the difference I am paying for?

Sand casting moulds a pattern in packed sand: economical, coarser, and every surface carries the sand’s texture. Lost-wax invests a wax original in ceramic that captures fingerprint-level detail, burns the wax out, and pours into the void — finer surfaces, undercut ornament, and a casting that reproduces the model rather than approximating it. For hardware and plaques the difference reads at arm’s length; for sculpture it is the whole craft.

What bronze do you pour, and does it matter?

Silicon bronze as the house standard — the modern casting alloy: pours beautifully, patinas honestly, and stands outdoors without the dezincification that attacks brassier alloys. Statuary bronze and everdur are poured to specification for restoration work where matching the original alloy is part of the brief.

How do I choose a patina?

With a tile set in the garden, on the actual site, over a week. Bronze does not have a finish colour; it has a direction of travel, and the patina chemicals set the itinerary — traditional green, statuary brown, or the honey of hand-waxed bare metal. We make the samples, the site makes the decision.

Can you cast from an original we own?

Yes — the mould is taken in our shop with the original in your sight, rubber and plaster against the surface, and the original returned before the wax is chased. The mould remains yours, and the casting is cast from a wax pulled from it — nothing touches the original but the mould, and the mould touches it once.

Bring the words, the photograph or the broken piece.

A plaque starts with your text; a restoration starts with the fragment; a sculpture starts with a conversation. The wax approval and the fixed quote follow inside two weeks — and the pour day invitation follows the wax.
