Short description of the bronze manufacturing process.     

The artist initially creates his work using clayey earth.

Once dried, this earthen work is placed in an oven heated to about 1000 degrees to give it a stronger consistency

The process used to create the bronze is to make a first elastomer mold that will be used to produce a wax copy of the original work.  

The wax obtained is then covered with a kind of plaster.

This set will be baked to melt and remove the wax.  Then, in this "plaster" mold, cast bronze will be poured into the space left by the wax.

All that remains is to break the plaster casing to get the bronze object.
