A Cire Perdue (Lost Wax Method)

We work according to the lost wax method, also called à cire perdue. This method is used to cast works of art and is also the oldest method of bronze casting (from ± 3000 BC.)

Waxmodels are heated in molds (±three days at 700° C) after which the bronze can be cast in these contramolds (at a  temperature of ±1150° C).

Small statues can be cast with a spoon. Statues from ± 10 kg and more are cast by pouring the liquid bronze directly from the crucible.

Bronzecasting following the "lost wax method"

To make a waxmodel from a statue (indirect method) we use silicon molds. In these molds the wax is poured (hollow or massive). In this way you can obtain a waxmodel from a statue of stone, clay or other material.

If the statue is already made in wax, it is not always neccessary to make a silicon mold. In that case we use the direct method.

A Silicon mold The (hollow) waxmodel from the mold


The (hollow) waxmodel gets a casting tap, casting channels and air channels before being formed into a second mold. This mold goes into the oven for 3 days at ± 700 ° C. This gives the contramold in which the bronze is cast.

and the bronze is cleaned

with water, this is the result


After the bronze is cast, the molds are then broken. The bronze is cleaned with water and then the chasing of the rough bronze statue begins. The casting tap, the casting channels and the air channels are sawed off, the holes are welded and the casting skin is brushed. Also polishing a statue or a part of it can be part of the process. The last phase is the colouring or patination of the bronze. We do this by heating the statue and bring on different kinds of sours (a.o. ironchlorid, coppernitrate, zwavellever, salpetersour).

This colouring can also be done with "cold patina".
