The lost wax process has been used for thousands of years and enables anything modelled in wax to be accurately reproduced in metal regardless of the complexity of its design.
Most fine jewellery made from silver and gold is made using lost wax casting as it produces the highest detail.
You create a wax imprint of your child’s fingerprint and send this to us. We add a connecting link or “sprue” to your imprint, which is then joined to a base and placed into a metal holding container or “flask”.
Next, gypsum plaster is mixed with water and poured into the flask totally covering the wax. Once the plaster has hardened, the flask is placed in a kiln and the temperature slowly raised over a period of several hours.
The high temperature causes the wax to be lost by evaporation and melting. A cavity bearing the exact imprint of the original wax model now remains - a perfect mould.
Molten silver or gold is then forced into the mould aided by a vacuum. Once the flask and metal cools, the plaster is then carved out to reveal an exact replica of the original wax imprint in silver or gold.
The lost wax process faithfully reproduces every detail of your original imprint with the addition of the sprue, which we carefully remove.
Finally, the charm is then painstakingly hand finished, cleaned and polished, creating your finished Precious Charm.
