Mould Making

Mould Making

 

We offer a wide range of different mould making techniques and materials, each one is appropriated based upon the size of the work, the number of editions the material used in creating the original and the material in which the piece is intended to be reproduced.

Ultimately our intention is to create an accurate copy of the original, replicating any surface detail, from a tiny fingerprint through to heavily under cut and textured surfaces.

The most commonly used method for mould making, consist of poured rubber or an applied rubber that reproduces the surface detail and this is supported with a resin or polymer plaster laminated jacket.

We work up to the scale of a full size figure and can create moulds in your studio or in our workshop. We are able to make moulds from materials, such as stone, resin, glass, foam, clay, fired ceramic, plaster and delicate ephemerals such as paper, fabric and organic matter.

Patination

Patination Process

 

We understand that patination can be the defining element of a bronze sculpture, we have spent many years researching, developing and creating genuine patina's for silicon bronze.

Our approach is to not produce a range of patina's to select from, we prefer to work closely with every client and develop bespoke patina's, each one specifically created to fit a sculpture or a design brief.

Bronze patination is a process of binding translucent or opaque layers of colored oxides, metal salts and pigments, to the surface of the bronze. A single patina is generally made from multiple thin layers that have been applied to a cold or heated bronze surface, the colors and patterns are formed by both a reaction to the bronze and the method of application.

 Each patination is recorded as a recipe, along with its application method and outcome. Its very difficult to recreate an absolute match, as each application has many variables and its own unique handmade quality.

The examples below are just a small section of what is achievable, it's possible to evolve any number of new patina's using these as starting points, we can also use any combination of these examples upon a single form.

Bronze Casting

Bronze Casting Process
 

 

We are one of a few commercial foundries in the UK that chooses to use a traditional lost wax plaster block investment technique. It provide us with an intuitive and versatile method for casting bronze and remains in keeping with our approach of working by hand.  

The casting process begins by encasing, a single wax sculpture, a series of small sculptures or a segment of a much larger sculpture, within a refractory plaster block or mould. To remove the wax from the mould, it is first steamed and then loaded into our kiln. We fire the kiln slowly through a 8 day cycle, which drives out all of the remaining wax residue and removing any moisture from within the plaster.

 The plaster block moulds are left fragile from the firing, it is at this stage they are at their most vulnerable. Each mould is carefully reinforced with a plaster and hessian jacket, they are blown out to remove any partials that might remain inside the mould void. 

Molten bronze is poured into each individual mould, filling the void where the wax sculpture was once encased. The moulds are left to cool for 12 hours and then broken open to reveal the bronze sculpture within.
