Casting the metal.
Bronze casting and cooling “the Burkinabé” traditional method of bronze casting uses various recycled metals (bronze, Tin, copper, zinc) carefully mixed while it is brought to a temperature of 1200°C. At the last seconds of the heating process, the caster adds a handful of charcoal on the top of the Crucible; the mold is then well wedge in the sand. The melted bronze is then poured into the crucible using a ladle
The artwork, once polished, reveals the yellow / red bronze. However most of bronze statues are green, brown. The process of application of a patina (liquid composed of water and several secret ingredients) on the parts of the artwork heated with a blowtorch, gives this oxidized color to the statues.
Art foundries are both ancient and modern; art craft means only their implementation.
