How We Make Our Cornish Tin Jewellery: Traditional Methods
Every piece of South Crofty Collection jewellery begins with the same raw material: pure Cornish tin from the historic South Crofty Mine. But the journey from raw tin to finished jewellery is one of genuine craft — a combination of traditional techniques passed down through generations of Cornish metalworking. Here's an honest look at how we make our pieces using traditional methods.
It Starts with the Tin
Before any making begins, the tin must be prepared. We work with pure Cornish tin — not tin-plated steel, not pewter, not alloy. Real tin, with all the qualities that make it both a pleasure and a challenge to work with. Tin has a low melting point, a distinctive lustre, and a softness that rewards skilled hands. It is a material that demands respect and rewards patience.
Method One: Melting, Pouring, Rolling and Texturing
One of our most traditional processes begins with melting the tin down and pouring it into smaller ingots — manageable blocks of pure metal that form the starting point for sheet work. Once cooled and set, these ingots are rolled out into flat sheets of the precise thickness required for the piece being made.
From here, the real craft begins. The rolled tin sheet is then worked by hand — textured, hammered, or patterned using traditional tools and techniques. Hammering creates the distinctive dimpled, organic surface you'll see on many of our Kerenza range pieces; texturing tools create repeating patterns that catch the light in unique ways. Each piece emerges slightly different from the last — a natural consequence of working by hand.
Once the surface has been worked, the piece is cut to shape, then carefully finished and polished to bring out the natural warmth and lustre of the Cornish tin. The result is jewellery that is unmistakably handmade — with a character and depth that machine-made pieces simply cannot replicate.
Method Two: Forming
Forming metal is the process of shaping metal into a desired form without removing material. It involves applying force through techniques such as rolling, bending, drawing, melting or pressing to change the metal's shape while retaining its strength and integrity. Unlike machining, which cuts away material, forming redistributes the metal to create components and shapes. In jewellery making, metal forming is used to create everything from the delicate curves of our trinket dishes to the wire we use for our bezel settings. It is a fundamental skill that combines precision, craftsmanship and an understanding of how different tin behaves under pressure,.
Method Three: Smelting and Sand Casting
Sand casting is one of the oldest metalworking techniques in the world — and one that Cornwall's mining communities would have recognised immediately. We use it for certain pieces where the process itself contributes to the character of the finished item.
The tin is smelted and poured into a sand mould — a mould formed by pressing a pattern into a specially prepared casting sand. The sand holds the impression of the design, and the molten tin fills it to produce the casting. Sand casting produces pieces with a slightly different surface quality to centrifugal casting — often with a subtle texture that speaks to the age of the technique.
Once cast, each piece is hand finished and polished — a process that can take considerable time for complex pieces, but which is essential to achieving the quality that South Crofty Collection is known for.
The Finishing and Polishing
Whatever method is used to create the raw piece, every item goes through the same careful finishing process before it leaves our workshop. Finishing involves removing any imperfections, refining edges, and preparing the surface for polishing. Polishing brings out the natural lustre of the Cornish tin — that warm, distinctive shine that sets it apart from silver or gold.
This final stage is entirely done by hand. It cannot be rushed. It is the stage that transforms a piece of worked metal into a piece of jewellery.
Made in Cornwall, by Hand, with Pride
These traditional methods connect us directly to Cornwall's long history of metalworking and craftsmanship. They are slower than machine production. They require more skill. They produce pieces that are never quite identical. And that is precisely the point.
When you hold a piece of South Crofty Collection jewellery, you are holding something made by skilled hands, using techniques with deep roots in Cornish craft tradition, from tin with a 400-year mining heritage. That is what handmade in Cornwall truly means.

Who Actually Creates the Pieces?
The South Crofty is a team of two (and a half if you count Tim!!), Sadie, Dawn and Tim. Sadie took over the business and has been making tin jewellery for 5+ years now as well as doing all the admin and social media, Tim is her husband who does the vulcanising and casting whenever he's not working at his real job!! Dawn started working with Sadie two years ago and splits her time between running the shop and making.
