A sketch is generous. It can taper to a needle point, suggest texture with three quick strokes, or curl into a shape that seems to float on the page. Metal is not so forgiving. It has weight, it cools, it shrinks, and it refuses to hold a detail that is thinner than a hair. Turning a drawing into a finished pendant, cuff, or miniature sculpture is therefore not a single act of manufacturing but a chain of small translations — each one made by hand, each one capable of losing or saving the idea. Understanding that chain changes the way you look at a piece of cast jewellery, whether you are buying it for yourself or choosing it as a gift.
Reading a Sketch Like a Metalsmith
The first translation happens before any metal is touched. A designer’s drawing has to be re-read as an object with a front, a back, an inside curve and a place where a cord will pass through. A hook pendant inspired by the sea, for example, may look elegant as a flat silhouette, but the maker has to decide how thick the spine of the hook should be so it does not bend, how deep the inner curve must sit so a braided cotton cord slides without fraying, and how sharp the tip can safely become. Every one of those decisions is made in the master model.
What a Master Model Actually Is
A master model is the solid, three-dimensional original from which every later copy is produced. Some are carved directly in wax by hand, using a scalpel and a heated tool for the fine lines. Others are sculpted digitally and grown in resin, then hand-finished with files and gravers until the edges feel right under a fingertip. Either way, the model is judged by touch as much as by eye. A ridge that reads beautifully on a screen can feel clumsy in the palm, and a surface that looks rough in a photograph may be exactly the texture a maker wants to catch the light.
This is also where shrinkage is planned for. Metal contracts as it cools, and different alloys contract at different rates, so a model destined for sterling silver may be made fractionally larger than one intended for bronze. In the case of Pakabone, master models are produced in Portugal and Italy, while casting takes place in the brand’s own workshops in Ukraine and Montenegro — a sequence the company states it does not outsource. The practical benefit for a buyer is continuity: the drawing, the model and the poured metal stay inside one chain of hands rather than being passed between unrelated suppliers.
Wax, Heat and the Moment Metal Takes Over
Most handcrafted casting still follows the lost-wax method, a technique older than written history and still unbeaten for capturing fine detail. A rubber mould is made from the finished master model, and wax is injected into it to produce a pattern — an exact, slightly fragile twin of the original. Several patterns are attached to a central wax stem, forming what makers call a tree. That tree is lowered into a steel flask and surrounded with a plaster-like investment material, which sets hard around every curve of every wax piece.
The Kiln Does the Vanishing
The flask then goes into a kiln. Heat melts the wax away and burns out every trace of it, leaving a hollow cavity in the shape of the original — hence the name lost wax. At the same time, the investment is strengthened by the firing, so it can withstand what comes next without cracking. Meanwhile, in the workshop, the chosen alloy is melted in a crucible until it moves like liquid glass. It is then driven into the cavity, either by centrifugal force or under vacuum, so that it reaches the thinnest fins, the finest scale patterns and the deepest recesses of a design.
The choice of alloy matters as much as the drawing. Sterling silver flows brightly and takes a high polish, which suits elegant amulets and slim bangles. Bronze — an 88% copper, 12% tin mix — has a warmer, heavier presence and holds a sculptural patina well. Silver-plated bronze offers the pale look of silver over a bronze core, while jewellery pewter is well suited to small figurines and talisman statues where softness is not a problem. Pakabone states that its pieces are free from nickel, lead and cadmium, which is the kind of detail worth checking when a gift is intended for someone with sensitive skin.
Quenching, Cutting and the First Real View
Once the metal has filled the cavity, the flask is left to cool, then broken open. The cast tree emerges grey and dusty, still joined to its central stem. Each piece is cut free with a jeweller’s saw, the stub of the sprue is filed down, and for the first time the maker sees whether the sketch survived the journey. Small flaws — a bubble, a blurred edge — are reworked or, if serious, the piece is recast. It is a slow, small-batch rhythm rather than a production line, and it explains why handcrafted casting carries a character that stamped or machine-cut pieces rarely match.
Finishing, Cording and the Gift-Ready Moment
The casting is only half the object. What follows is the quiet, patient work of finishing: filing away seams, sanding through successive grades of abrasive, then polishing on a rotating mop charged with compound until the surface goes from dull grey to a deep, wet-looking shine. Delicate areas are often darkened deliberately, so that recessed lines hold shadow and the raised shapes stand out sharply — a technique that flatters ocean-inspired forms such as shells, fins, scales and carved hooks. Every step is done by eye and by hand, which is why two pieces from the same mould can still differ slightly in the way they catch the light.
Assembly is its own craft. Bracelets, cuffs and bangles are checked for how they close and how they sit on the wrist; pendants are threaded onto braided cotton or leather cord in a wide range of colours, with the cord’s thickness chosen to match the weight of the metal. In Pakabone’s case, this assembly and the final packaging happen in Portugal, and the brand notes that pieces ship worldwide, usually within one to three business days, with tracking and gift-ready presentation. You can see how those final details resolve in real pieces at https://pakabone.store, where the collections run from shark and reptile totems to Hei Matau hooks and small talisman statues.
For anyone shopping for jewellery or a gift, a little knowledge of this process is genuinely useful at the moment of choosing. Look closely at the edges of a cast piece: crisp, clean outlines suggest a well-made model and a clean pour, while soft or bubbly borders hint at a rushed casting. Turn the piece over and check the back, which is where shortcuts usually show. Feel the weight against its size — bronze and pewter should feel substantial, silver should feel dense rather than hollow — and check that the cord or clasp sits smoothly with no sharp burr waiting to catch a sleeve or a strand of hair. A handcrafted piece made this way carries the record of its own making: the first drawing, the carved model, the molten moment, and the long polish that finally turns a sketch into something you can wear or give away.
