We have our own casting equipment in our workshop enabling us to cast using the lost wax casting technique. We are able to cast onsite in all colours and carats of gold as well as sterling silver.
We also use external casters in Hatton Garden for platinum casting, and more specialist mould making of replica pieces.Please note
we are a retail business only, and do not offer trade services.Lost Wax Casting
With his method we start with either a wax model, or 3d print of the required item of jewellery.
We then place the wax or model into a cylinder and fill with a ready mixed investment (like plaster of paris)
The cylinder is then left for the investment to solidify and dry. It is then baked at various temperatures for around 8 hours to melt the wax or 3d print out to leave a hollow void.
We then transfer the cylinder (we call it a flask) to our casting table. The table has a vacuum which sucks air through the tiny microscopic holes of the baked investment allowing the molten metal to be sucked in to all areas of the mould.
Once the gold has melted we then pour the liquid metal into investment for it to flow through the mould.
We now have a cast piece of jewellery that probably started as just a drawing on our computer screen.Delph Clay Casting
Delph clay is a very fine clay, that when compressed on to an item retains incredible detail of an item. We cast with Delph clay by compacting an existing item into the clay to make a hollow void. Cutting a pouring hole into the clay and pouring molten gold in.Cuttlefish Casting
An old traditional technique that involves using cuttlefish either from a pet shop or simply picked up from the beach.
We cut the cuttlefish in half and sandpaper the soft side flat. We then push the two halves together with our model between. This then makes a void within the cuttlefish.
We the cut a channel into the cuttlefish to pour the liquid gold in.
