Investment casting is one of the oldest known metal-forming techniques, dating back 5000 years. Original investment casting involved the use of beeswax. Today, high technology waxes, refractory materials and specialist alloys are used to produce jewellery, ratchets, turbine blades, gears and complex machinery components.

The investment casting process starts with the creation of wax designs, attached to a sprue to allow it to form a tree of pieces. The tree is set into a flask ready to invest. A ceramic mixture, known as investment, is poured into the flask over the wax tree, filling the flask, using vibration to bring air bubbles to the surface. The flask is then settled into an oven for overnight heating, drying the investment. Once dry the wax tree is vaporised through the use of heat. Bronze granules are weighed and poured into the furnace. The molten metal is released into the investment, filling the wax tree footprint. The flask is removed, cooled and blasted by water jets to clean away the investment revealing a cast tree of pieces within. The pieces are then taken to be de-sprued, cleaned, soldered, polished and plated.

This collection sees us working with a family owned casting house in the jewellery capital of London, in possession of a Royal Warrant and renowned for its restoration work for the Royal households.
